Rehabilitation of the N9 National Road, Mbalmayo-Sangmélima: how will the work be carried out?

The rehabilitation project of the N9 National Road will be executed in three lots and will put forward a process of recycling of the pavement. More explicitly, the project consists of the rehabilitation of 115 km of road with the following specificities at the level of the pavement: cold in situ and continuous improved emulsion recycling (EIR) of the existing emulsion pavement, for the base and sub-base layers, including the shoulders; the additional contribution of 0/31.5 NGT materials for recycling and eventual recharging; the emulsion impregnation with sandblasting and the laying of a two-layer surface dressing on the pavement and shoulders.
Indeed, the works on the first lot, which extends over 39.5 km, will be executed by the company ROUTD’AF; the second, 42.5 km, is covered by the company ARAB CONTRACTOR and the third, 33 km, by RAZEL Cameroon.

As for the pavement works, they include the clearing of potholes; the cold recycling in situ of the existing pavement with emulsion, for base and sub-base layers; the additional supply of 0/31.5 GNT materials for recycling and possible recharging; the emulsion impregnation works with sandblasting; the application of the two-layer surface dressing on the pavement and shoulders. The project also includes drainage, signalling and safety equipment.
