Over recent years, a new term has come into usage in the asphalt vocabulary, namely ‘warm’ asphalt mixes.
A general increase in environmental awareness means that a considerable amount of attention is now paid to this type of asphalt mix, mainly regarding the reduction of exhaust gases into the atmosphere, in accordance with the directives of the Kyoto protocol.
Recent developments into various production techniques of warm asphalt mixes have led to the release of a new range of products onto the market.
And this, in turn, has resulted in the redesign and modification of asphalt plants, to cater for these new methods and to guarantee that the quality of the final product is, at very least, equivalent to the quality of traditional hot mixes.

While the production temperature of traditional mixes ranges from 140°C to 180°C, new plant solutions and technical developments have now made it possible to produce asphalt mixes at a temperature between 90°C and 120°C, in complete compliance with work specifications.

Studies in this field were first carried out in 1995 and preliminary trials were conducted in 2000. Nowadays various, well-tested technologies are available which allow work to be effected at low temperatures without compromising plant performance. Also, the roads built with this type of product and methodology have now been tested over long periods of time and their behavior can certainly be considered similar to (or, in some ways, even better than) traditional asphalt mixes.

But why do we need to produce asphalt mixes with lower than standard temperatures?
First of all, less energy is required (lower burner consumption estimated in the range of 20% to 40%) with consequent reduction in the fumes volume, especially CO2 and COT emissions. As you can see in the following photo, plant working conditions are considerably improved, with almost complete elimination of emissions and a sensitive reduction in the odor of the asphalt (in fact, working at temperatures lower than 130°C considerably cuts down on fumes/odor problems).

Even more important are the advantages experienced on the work site. Working at low temperatures greatly improves conditions for paver finisher workers, the road works can be quickly reopened to traffic, production time and laying time can be lengthened, and features of production may be improved such as the reduction of oxidization with consequent bitumen aging. Then added to all this is the reduced environmental footprint, especially in urban areas.

Why is there a reduction in burner consumption?
The following diagram illustrates the linear increase in fuel consumption as the temperature increases.
When 100°C is reached a high burst of energy is experienced due to the heat of vaporization (this consumption is connected with aggregate moisture).
Once the aggregates are dried, the temperature continues to increase together with fuel consumption. Therefore, if the production temperature is reduced, let’s say from 160°C to 120°C, the 40°C reduction in final aggregate temperature results in a saving of around 1 kg of fuel per ton of asphalt produced.

The present state of the art envisages a series of additives which allow this type of work to be carried out using existing plants without having to make major alterations.

Solid additives may be fed into the mixer in the form of crystals which contains up to 20% of their weight in water, which is then released at temperatures exceeding 85°C, creating a ‘foam’ inside the mixer and encouraging correct bitumen adhesion to the aggregates, even at lower than standard temperatures.

To introduce these additives the plant must be fitted with a pneumatic metering system into the mixer. (Trials have also been carried out feeding the additives from sacks onto special chutes, a method which has not at present been optimized).

Different types of wax may also be melted into the bitumen. These are a kind of paraffin which is fully soluble in bitumen at temperatures over 115°C and reduce the bitumen viscosity, therefore allowing mixing at lower temperatures.

The asphalt plant must be equipped with a wax storage and feeding system into the bitumen circuit. (Alternatively, these waxes may be fed directly into the bitumen tanks but, again, this method has not been optimized, given the difficulty in managing the correct quantities of bitumen and additive).

Several liquid additives exist which allow bitumen viscosity to be reduced to work temperatures. With this solution, the plant must be fitted with a feed system for metering small amounts of additive into the bitumen weighing recipient.

There are further interesting technologies requiring considerable intervention on existing plants and/or completions on new plants, but which guarantee even better plant performance than other methods. In particular, we cannot fail to mention the new generation of TOP TOWER plants which are already fitted out for use with all available market technologies.

The double mixing method is especially interesting: the first mix is low temperature aggregates (around 120°C) with high penetration bitumen; the second mix involves low penetration bitumen ‘foamed’ on its special ramp.
This technology allows work to be carried out at very low temperatures and with the use of high percentages of RAP; this method does however require major plant adaptation, in particular with regard to bitumen storage (two tanks for the two special types of bitumen used), bitumen feed circuit, water, bitumen ‘foam’ ramp and software management for the whole process.

Another technology uses the introduction of wet sand into the mixer. This process again involves two successive mixing processes: firstly, for mixing large aggregates at 140°C with standard bitumen, then secondly for wet sands at ambient temperature whose water content creates a ‘foam’ effect and ensures the correct coating of aggregates even at low temperatures.
Excellent results are obtained with this methodology in terms of energy savings and emission reduction. However additional material must be added to the site for feeding the sand into the mixer and, above all, equipment is necessary to correctly monitor the whole operation.

Warm asphalt mixes are a response to an attempt to produce a more eco-friendly product and reduce the environmental footprint.
The difficulty in proving the validity of these products has now effectively been overcome; the main problem faced today is making the practical step of introducing these technologies into the work specifications of public authorities.

Nowadays in Europe and throughout the world, ‘asphalt’ means hot mix, but in the space of just a few years ‘asphalt’ will come to mean warm mixes and, when this happens, asphalt plants are ready and waiting to take part in the green revolution. There are no general rules which are true for all sites and all clients, and so Marini is intent on working as a partner with each and every client, to analyze production requirements and to adapt the plant to suit every working situation.

Given the importance of this discussion, together with the fact that rising oil prices are making bitumen an increasingly precious product, many companies in the sector are now aiming at solving the problem, at least in part, by developing technological solutions which utilize both warm asphalt material and RAP, without compromising the high quality of the final product.

Consequently it is Marini’s intent, as market leader, to work alongside its clients in getting the most out of the plants and achieving the top in asphalt production, bearing in mind two key words: ‘recycling’ and ‘temperature reduction’.

Markets are changing and rationalising, while at the same time, the economic crisis is having a profound impact on our behaviour.
The FAYAT Group has adopted 5 main trends underpinning decisions:

Think ESSENTIAL

A “back to basics” approach, and/or an initial focus on identifying basic principles, which we refer to as the ESSENTIALS. These machines all feature the technical elements required for basic operations. This includes safety criteria and compliance with standards, but not all of the ergonomic and/or multifunctional options are necessarily included in the product range. The additional range offers so-called safety or ergonomic options, or based on geographical region and the user’s requirements. This trend, evident in the motor vehicle sector, should not be confused with a “low-cost” concept. That said, many recent machines were multifunctional and a small percentage of clients today want simpler machines, focusing on their initial vocation.

Think ERGONOMY
The quest for greater user-friendliness and advanced health and safety standards are decisive advantages, especially in mature markets. FAYAT automatically offers these solutions on all types of machines. Electronics, automatism and equipment maintenance management are considerations that are likely to vary significantly. In Europe, the Machinery Directive (2006/42/EC) gives clear guidance, aimed at harmonising the rules pertaining to health and safety. This is completed by so-called comfort solutions that are often held to be unquestionable.

Think ECOLOGY

The protection of the environment and the reduction of all types of emissions are powerful sources of motivation which vary from one country to another but remain inescapable and essential. The Directives on engine emissions (2004/26/EC) and sound emissions (2005/88/EC) are having a major impact on equipment development, particularly machinery fitted with new thermal, hybrid and even electric engines, which are managed by start and go or Ecomode type energy-saving systems. ECODESIGN, especially taking account of design and environmental impacts, including end-of-life recycling, from the outset, is defined by an ECODIRECTIVE (2005/32/EC).

Think ECONOMY

The search for ECONOMICAL solutions, given the economic crisis, is also a key parameter that influences the behaviour of decision-makers, but always in conjunction with one of the other parameters. A wide array of guidelines have therefore been developed, such as the design of high output machines. This trend is true for both road machinery and production plants.

Think EVOLUTION

Today, we think in terms of EVOLUTION rather than innovation. Innovation is, of course, still essential, but major innovation is rare. However, machines are adapted to the needs of their era and must evolve according to the technical demands and the available technologies for a
long time – at least as long as their service life. Modern production plants are versatile in the sense that their design enables a variety of materials to be produced, including low-energy asphalt, but they are above all “retrofitable”, meaning “modernisable”. A machine installed in 2010 will operate in 2030, with what binder? At what temperature and for which product? Our
technical visibility is shorter, the weight of legislation and economic aspects are changing, and as a result decisionmakers must go for an ADAPTABLE option.

The Adige Bitumi S.p.A. Group recently decided to renew its by now historic M 260 plant located in the Mezzocorona (TN) job site with a new plant and, in doing so, decided to place itself at the top of the Italian market, choosing to collaborate with Marini S.p.A. for the design and development of a plant with production of 280-300 t/h which can certainly meet the needs of the Italian market with specific reference to new technologies.

The primary input during the initial phases of the negotiation was that of being able to prepare a high potential plant (to best meet the needs of the clientele and its own paving crews), but above all to have a plant which is very best on a global level specifically with regard to the technological-ecological aspects (low atmospheric emissions, low noise, low energy consumption, maximum percentages of usable milled materials, possible use of all types of liquid and solid additives, etc…) and also the modularity (use of mobile metallic bases, external electrical wiring, etc…).

The owner, Paolo Tellatin, with his technical team had very clear ideas, thanks to the extended experience acquired on their own job sites (the group has five installations between Veneto and Trentino, besides a sixth plant installed in Belgrade) and so it was easy to find the right feeling in designing a plant so complex which, however, had to be placed in the same space as the old plant.

The plant was designed with a high number of pre-dosing units (12 for aggregates + 3 for the pre-processed and selected milled material) in order to guarantee maximum precision in dosages, also with an unequalled operational elasticity. It is also possible to feed the “hot” recycled material line at the recycling line with 2 pre-dosing units and the “cold” line in the mixer with 3 pre-dosing units (remaining in the spirit of being able to guarantee the highest quality products in any operating condition). Naturally, all of the conveyor belts were encased to be able to reduce the emissions into the atmosphere.

Thanks to the advantages of the “Drying tower” with the bag filter and the storage silo for the fine products located directly above the Drying drum, the TOP TOWER 4000 limits not only the ground dimensions, but above all guarantees optimisation of the heat energy balance (reduced length and insulated exhaust duct between the dryer and bag filter) and also the recovery of energy radiated from the drum. With particular reference to the concepts of reducing emissions and sustainable development, the Dryer burner was equipped with further atomization of the fuel with a dedicated air compressor and the plant was equipped with a Bag filter with an increased filtering surface as well as sleeves in Nomex 500 material.

With regard to the filler as well an optimisation never before achieved in Italy was realised. In fact, the plant is equipped with 2 separate silos for recovery of the fine products besides a silo for the intake filler, a cement storage silo and another for lime storage.

The use of a 6 selection screening unit was decided on for the mixing tower (in the completely covered version with significant reduction of noise and heat loss) with great ease of screen replacement and maintenance thanks to a new Marini patent which guarantees easy replacement of the screens and complete accessibility to them.
Maximum attention was given to ease of maintenance with direct and easy access to the 6 hoppers under the screening unit (besides to the direct discharge which was heated with electrical elements in order to optimise use of the milled material) as well as to the stairs and handrail complex (widened as required by European standards) which allow all of the plant maintenance points to be reached without having to descend to the ground once leaving the cab.

Significant care was also given to the aspect of reducing noise and atmospheric emissions and, from this point of view the coverings of the mixing tower and the finished product storage silo (with high storage capacity of finished product – more than 400 tons) were realised, also including the conveyor shuttle level. The bag filter with the entire drying tower were covered with roofs overhead and protective folded roof sheeting on the sides.

The cisterns have rock wool insulation with increased thickness at 200 mm (even on the bottom) in order to be able to reduce heat loss to a minimum and consequently consumption for heating the bitumen. 5 bitumen cisterns are provided with a capacity of 100 m3 each, 1 for combustible oil (capacity 100 m3 and 1 emulsion cistern divided into 2 compartments (60 m3 + 30 m3) to feed the plant spraying cisterns separately. 3 plant feeding lines were provided: 2 for bitumen with the possibility of blending (mixing 2 different types of bitumen in the same mixture to obtain a bitumen with intermediate characteristics) and also 1 emulsion line to be able to produce cold conglomerates.

The extensive efforts of the alliance between the Adige Bitumi Group and Marini S.p.A. led to the creation of a plant which promises to be a point of reference for a new, evermore demanding clientele which is more and more oriented toward quality as a key factor in order to attack the modern market while at the same time paying more and more attention to energy savings, environmental impact and company economy.

MARINI accompanies road constructors and reinforces its presence in the sub-continent

Navayuga installs India’s Greenest Asphalt plant :

Navayuga engineering company, known as one of India’s finest structural engineering company, chose Marini MAC plants for their Armur – Adloor Yellareddy road project on the Nagpur – Hyderabad section. A PPP project executed by Navayuga on  DBFOT basis.

Commitment to build the nation’s infrastructure, with no compromise on the environment, was the key, to Navayuga’s decision, to procure a series of MARINI MAC’s, states Blesson Varghese Marini India’s National Director.

Navayuga clearly understands that to realize profitability the only route is sustainable construction and high productivity, adds Navayuga’s project team leader. The top management team at Navayuga were convinced, that it was imperative  to minimise plant running costs, which could be achieved only by high reliability & productivity. Moreover the project’s nature demanded that high performance and absolutely high quality mix.

The new generation of energy efficient asphalt plants from MARINI has been developed to meet customers’ demands for versatility, quality and environmentally-friendly requirements. The first MARINI MAC commissioned by a team of engineers from MARINI INDIA, plant produced around 1200 tons of high quality mix on day one and has now almost fulfilled its project demands. The plant will be ready to move in early 2011, to another project site.

Zero Civil foundations, modular designs, zero ducts and minimal interfaces, ensured that the plant was put in to operation in a very short time. The plant manager, confirms that the entire process is so user friendly, that we feel confident that our own team could move the plant and re-commission it at the new site.

To minimise energy consumption at all stages of the process, the MARINI MAC uses a combination of innovative design along with waste heat recovery system, to bring significant energy savings throughout. The high efficiency dryer & blue flame assisted burner design provide savings of over 20 %, compared with traditional designs of asphalt plants in India.

KMC – decides to continue a decade long partnership

When KMC ordered two MAP 175’s more than a decade earlier, it shocked the industry professionals, as these plants were too large. However KMC proved their point by producing over 1.5 million tons of asphalt during the past decade with these plants.

These plants have completed several road projects and have been relocated numerous times. KMC’s Dynamic Director Mr. Pruthvi Reddy, states that MARINI plants have delivered them unhindered production and very high satisfaction. He boasts about the plants fuel efficiency and high productivity.  One of the plant is presently installed on the Pink City Expressway project and the second plant is installed in the highly environmentally conscious state of Kerala, where KMC, thanks to their impressive performance have been awarded two project extensions.

The partnership saga, hasn’t ended with these two plants, KMC has yet decided to install another MARINI plant for their prestigious 183 Km road project in Andhra Pradesh. The plant already delivered is expected to start commercial production by February 2011.

L&T achieves Record Production in India

The recently opened Terminal 3 at the New Delhi International Airport boasts of its Runway # 3, the longest in Asia, capable of accommodating an Airbus 380. During the first phase L&T, had a challenge to produce over 650 000 Tons of asphalt in six months. The daring L&T unsurprisingly took up this challenge with two Marini MAP plants of 260 and 200 Tph capacity, the largest production capacity ever installed in India.  L&T achieved this impressive target with over 100 000 Tons of mix being produced each month.

Top notch reliability, ability to perform under demanding conditions have been the main reason for the asphalt plants to deliver when L&T required it the most.  With the mega project already completed the plants have already being relocated to road projects in Gujarat & Tamil Nadu.

There is no stopping, Two 200 Tph Marini plants have also being employed to replicate the success story at the Mumbai International Airport Project.

When it comes to un-compromised mix quality, performance and reliability Marini asphalt plants have proved to be the favorite in India. Marini asphalt plants have being used to build most of the new age airports in India including International Airports  in New Delhi, Mumbai, Bangalore & Hyderabad.

RAMKY finds the ideal partner.

RAMKY Infrastructure Ltd, one of India’s leading company focused on sustainable development will install Marini plants on their large projects pan India. The first GREEN plant for RAMKY will be installed near Moradabad, around 100 miles from India’s capital city New Delhi. MARINI MAC series of asphalt plants were the ideal choice for our company, as it gels so well with our corporate focus on sustainable development  sates Mr. M Kumar – Head Supply Chain Management. Mr. Haribabu, the company’s Vice President says, we chose Marini because our projects required high performance machines and top notch reliability, to ensure our progressive stride.

The  MAC delivered to RAMKY has been supplied with Multi fuel capabilities, RAP processing abilities and a host of other green features. With RAMKY and FAYAT Group, both focused on sustainable development, India is about to witness a great confluence of technology and commitment – delivering crucial infrastructure which is profitable and green.

The first generation asphalt plant “TOP TOWER 3000” built with sustainable development in mind has been further implemented and improved resulting in a new model:  TOP TOWER 4000

In the last years Marini and Fayat Group have been focussing on developing innovative asphalt plant solutions and taking it to the top worldwide, keeping an eye on the technological-ecological issues (significantly reduced emissions to the atmosphere, low noise levels, low energy consumption, high rate of reclaimed material, …) and on the modular concept (easy transportation, rapid assembly and eventual subsequent disassembly, use of mobile steel foundations, etc…).

Besides that, it is very easy to move up – even at a later date – by fitting kits providing the most innovative technologies available on the market (warm mix asphalt, clear bitumen, liquid and solid additives, use of high content of reclaimed material, …).

The above features are behind the success of Top Tower 3000, which has been marketed for three years now and increasingly appreciated by the main contractors in the field.

Later on, Fayat Group has decided to develop a new model, featuring all the innovations of its forerunner and also new improvements, that are now placing the Top Tower 4000 at  the top in terms of quality and market demands.

Thus, Top Tower 4000 maintains the advantages of the drying-filtering unit. The decision to position the filter and the storage silo for the recovered fines directly over the dryer drum, not only reduces the footprint, it has also a very positive impact on the plant consumption of electricity thanks to the optimised flow of gases (shorter, partly insulated dryer-filter duct) and the recover of the heat energy radiating out from the drum.

In conclusion, the Top Tower innovative design leads to substantial savings, both in the consumption of electricity and fuel. Therefore, this plant contributes to the reduction of CO₂ emissions and operate in complete accordance with the principles of sustainable development.

The essential part of the Top Tower – the mixing unit – has been completely redesigned, starting from the screen which is provided with full cladding (for reduced noise levels and heat loss). Great efforts have been paid to facilitate screen mesh replacement and servicing; thanks to a new system – Marini patent – the screen meshes can be quickly dismantled and replaced and the access points are larger and more comfortable.

The access to hot bins as well as to ladder and catwalks (larger as provided by the new European standards – no vertical steps) is easier thus allowing to reach all servicing points from the cabin without stepping onto ground.

With a view to reduce noise levels and CO₂ emissions, the mixing tower and the hot mix storage bin, including the travelling skip, have been designed to incorporate complete or partial cladding: as such all the elements generating noise or vapour emissions have been re-engineered and optimised.

Top Tower 4000 is the only plant which structure is fully designed to comply with the seismic norms standardized all over the world.

Top Tower is the synthesis of an ongoing collaboration with top level customers, which allowed Marini to update and improve the plant paying particular attention to production management, routine maintenance and energy consumption.

The experience and work of Fayat Group have resulted in a functional and highly efficient plant, responding to the market requirements. Top Tower 4000 is meant to be a reference product for a new demanding and quality oriented clientele.

The German contractor Johann Bunte, a road specialist with three asphalt plants, has fixed the target to optimise production of hot asphalt and to reduce the consumption of energy. Some kind of green approach for black asphalt. To meet this target, the rates of recycled asphalt pavement in the mixture must be dramatically increased.

The production process needs some optimisation and the electric consume of all major drives must be minimised by frequency converters.

The existing batch mix plant from the year 2005 was retrofitted two years ago by an ATS/MARINI recycling ring on the existing dryer to increase recycling rates. The existing RAP cold feeding into the mixer was insufficient with only 20 %. By retrofitting the recycling ring, the feed rates could be increased up to 40 % and more.

For big production runs and highest RAP rates it was necessary to install a powerful parallel dryer with burner for lignite dust and gasoil. ATS received the contract to do this retrofit together with installation of frequency converters for both dryer drums and the big filter exhauster. The complex control task could not be handled with the existing controls of the competition. So it was necessary to install the latest generation of ATS/MARINI plant controls. By mouse click all process can be started, changed, and supervised and the batch log registers all parameters, consumes, and events.

The highlights of this project are as follows:

A parallel flow dryer drum for RAP with a nominal output of 180 t/h with variable rotation speed to achieve temperature of the RAP material at dryer discharge between 140 and 160° C.

The exhaust fumes temperature shall not be higher than 10 – 15 K above product temperature. To meet this target, the drum was sized with 2,5 m diameter and a length of 14 m. Drum and drives were designed by Marini and ATS in close cooperation.

The height of the elevated mixer gave input for the position of the drum under consideration of a buffer hopper of 26 t, a separate weighing hopper 3 t, and a highly inclined chute into the mixer. The result was a height of 32 m and a very heavy steel structure.

The hoppers for the hot RAP are perfectly insulated and electrically heated. The chute into the mixture is highly inclined with special steel surfaces and is heated and insulated to avoid any sticking.

The heat for drying the RAP is generated by double fuel burner for coal dust/oil. The application of these burners in recycling parallel dryers is a new technology and needs special care when designing the combustion area.

The problem is to transfer the heat into the sensitive RAP material by avoiding overheating and damage of bitumen. RAP shall never become too sticky, otherwise all the lifters will be blocked.

Special flights were designed and installed. So the drum performed in reality better than expected.

For parallel operation of two dryer drums (virgin aggregates + RAP) the regulation of low-pressure at the burner front wall is quite complicated and needs two servo controlled dampers for both fumes ducts and a constant under pressure in the raw gas duct ahead of the bag filter. Existing exhauster is speed controlled with a new frequency converter to keep this constant low-pressure in the main duct. 200 kW exhauster (operated with frequency converter) has no further peaks at “switch on” and minimised electric consume during all operation. The reduced noise ís an additional benefit.

At high recycling rates, the virgin dryer with only minimum aggregates flow is changing dramatically the heat transfer and temperature conditions. Only with speed controlled rotation the parameters of operation can be influenced.

The newly developed ATS/MARINI burner control system receives additional input by belt weighing scales indicating material flow into the drum. It calculates any change in material flow for changing of burner capacity in due time for a constant product temperature. This offers additional savings in energy and improvements of the asphalt quality.

Competitor’s controls, just 3 years old, were completely replaced to implement the complex controls procedures for ATS burner system and RAP dryer.

The concept developed with the customer Bunte, did proof its performance and capacity during the first major productions with a daily production above 2.500 t and a recycling rate far above 60 %.

Erection and commissioning took place within 2 months without major interruptions of ongoing production of hot mixes.

A success story for the leading asphalt technology, developed in the multinational business area Asphalt Plants of Fayat Group.

JOB REPORT KOLO VEIDEKKE, ARABIA SAUDITA

Water is the greatest of elements in nature, being essential to support life of the whole system. Dam construction for collecting the precious water for irrigation or human consumption is therefore necessary in big parts of the world.

The company KOLO VEIDEKKE (Norway) has specialised in dam construction using very dense asphalt as a central core in such dams. The asphalt characterised with a high content of bitumen and fines is placed in 20cm layers on top of each other in the centre of the dam. Such dams are now under construction in Saudi Arabia, not far from Jeddah. The first dam, 30 m high is completed and the next one, 100 m high is under construction having so far placed 170 layers on top of each other. It is essential to make and place a 100% water proof asphalt to prevent any leakage of the dam.

The thin asphalt core is the black line in the middle of the dam.

A reliable and precise plant is needed for this particular application. As the required production is not very high, the Marini asphalt plant ULTIMAP1300 B4 E190L was chosen, with the following technical configuration:

• Cold feeders unit type 100 VI transportable, with 4 compartments, unit cap. 9,6 cu.m.
• Dryer-drum unit E190L, with dual burner for diesel and heavy fuel oil, and fitted with a recycling ring (due to the required mix temperature over 180 °C)
• Bag filter FM500/50 and preseparator
• Screening, weighing and mixing tower ULTIMAP1300, with a 4 meshes screen and 1 additional by-pass. High efficiency screen >95% was required
• Hot storage under screen, 4 compartments, cap. 12 cu.m.
• Control cabin & production management automatism; perfect dosing of bitumen content
• Hot mix asphalt storage by side, cap. 25 cu.m.
• 200.000 kcal boiler and 1 bitumen tank cap. 50.000 lt
• Stack-up silo for imported filler and recovered fines, cap. 23+23 cu.m.
