The project
The Murtala Mohammed International Airport Road is used by an average 50,000 vehicles each day, making it one of the busiest roads in Lagos State. This volume of traffic places particular strain on roadways, and recently the need not only for rehabilitating the road, but for the total transformation of the Oshodi-International Airport corridor became clear.
The team
Lafarge Africa Plc partnered with the contractor HiTech Construction Company Limited on this project, with their Road Segment delivering the soil stabilization phase.
HiTech and Lafarge Africa’s collaboration on soil stabilization on road projects started in 2013. In 2014, the use of Lafarge’s RoadCem product was researched for a specific project in Oshogbo, Osun State. The field trial of the solution was successful. This outcome coupled with further partnerships made Lafarge Africa Plc the service provider of choice for the prime International Airport Road project.
The solution
Lafarge’s RoadCem is used for permanent physical and chemical alteration of soils to enhance their physical properties. It is a cement stabilization product suitable for poor soil conditions in road construction and provides customers with a cost effective product that enhances the speed of construction. About 3600 tonnes of Roadcem were used in the rehabilitation of the Airport road’s sub-base and in cold recycling of asphalt.
Following the successful delivery of this project, the Federal Ministry of Works has approved the trial of RoadCem in the soil stabilization process of a 1km section of the Otta – Abeokuta, 80Km Road. Discussions are at advanced stages on the use of RoadCem in various projects across Nigeria.
