As part of the funding granted by the Debt Reduction and Development Contract (C2D) between France and the Ivory Coast, on 21 March 2018 RAZEL-BEC, as part of a consortium, signed a contract with the Ivory Coast Department of Economic Infrastructures to reinforce the Bouaké-Ferkéssedougou section of the north road.
The work on this 95 km section, which will take 22 months, consists mainly in:
- recycling the existing roadway by adding cement and granular materials to obtain a 25 cm (257,000 m3) foundation layer,
- laying a crushed-stone base course 0/20 (94,000 m3) and an asphalt surface course 0/10 (720,000 m2),
- improving the longitudinal and transversal sanitation (144,000 linear metres of concrete-covered earth trenches )
- supplying and installing the roadway equipment.
The contract also includes building 8 km of highways through the neighbourhoods through which the project passes as well as the construction or renovation work of state schools, health centres and drinking water well boring for the local populations.
The difficulties posed by this building project are the very restrictive deadline, finding and producing road aggregate (which is difficult to find in the area) and the procurement logistics in this part of the country. A real challenge that the RAZEL-BEC workers will take up.
