Implanting better roads

摘要

A new up to 180tonnes/ hour Marini UltiMAP 2000 plant is helping Lagos State Public Works in Lagos, Nigeria implement a five-year strategic road map aiming to ensure high standards of road maintenance and improve infrastructural development across the city of more than 17 million people. The new UltiMAP 2000 model which started work last year in the Lagos suburb of Imota is the result of Lagos State Public Works (LSPW) emphasising their need of a highly flexible plant allowing high quantity usage of RAP [Recycled Asphalt Pavement], in order to break with a countrywide tradition of failing to recycle existing asphalt pavement. To meet this request, Marini's technical team firstly decided on a plan whereby the client would pre-treat the RAP in order to control the quality of old bitumen and the size of recovered aggregates (the highest quality of the final product has always been a priority in the technical discussion) and then use a bespoke Marini UltiMAP 2000 plant solution with one line to the dryer (recycling ring) offering up to 35% recycling.
