Nigeria: LSPWC choose a MARINI asphalt plant for Lagos


A new up to 180 TPH Marini Asphalt Plant UltiMAP 2000 is helping Lagos State Public Works Corporation in Lagos, Nigeria implement a five-year strategic road map aiming to ensure high standards of road maintenance and improve infrastructural development across this city of more than 17 million people.
MARINI asphalt plant in Lagos, NigeriaThe new UltiMAP 2000 model which started work last year in the Lagos suburb of Imota is the result of Lagos State Public Works Corporation (LSPWC) emphasising their need of a highly flexible asphalt plant allowing high quantity usage of RAP [Recycled Asphalt Pavement], in order to break with a country-wide tradition of failing to recycle existing asphalt pavement. For this reason they firstly decided to pre-treat the RAP in order to control the quality of the old bitumen and the size of the recovered aggregates (the highest quality of the final product has always been a priority in the technical discussion) and it was decided to choose a plant solution with one line to the dryer (recycling ring) with up to 35% recycling.
Other important points evaluated during the negotiations between Marini’s Nigerian dealer, HMD, and LSPWC were the possibility to control, in the best possible way, the metering processes (for single components), the ability to frequently change the formula in production, and the possibility of producing small quantities of asphalt. There was also said to be a focus on maximum plant efficiency, the production of special products (possibility to use coloured additives and fibres), and the environment and working conditions.
Asphalt Plant Inauguration in NigeriaLSPWC requested a special bitumen supply facility, and the UltiMAP 2000 plant at Imota has a total bitumen storage capacity of 300 tonnes, granted by six vertical tanks. The operator can easily change the type of bitumen during the HMA (hot mix asphalt) production and can also order the bitumen from the supplier who will deliver within an agreed timeframe. These peripherals are said by MARINI to be common to all asphalt plant supply deals, but the request was for new design tanks with low thermal bridges as they have to consider production process optimisation, the environment and, of course, the most economical mode of production in terms of efficient use of raw materials.
At the end of the day, a new point of reference is now reached for Nigerian market and we are sure that also other contractors (as already done by Lagos State Public Works) will search for all operational optimization in order to respect the environment, to reduce the fuel consumption, to optimize the emissions and especially taking into account the target to maximize the quality of the final product.
