> The ICA - ITECH - RINCENT BTP SERVICES - ROAD & D group has been working since mid-2018 on the development of a road reinforcement guide for AGEROUTE in Senegal.
The principles of the approach are based on in situ investigations, mainly pavement surveys that will lead to an assessment of the existing roadway and its need for reinforcement.
The rational method proposed is based on the French standard method adapted to the context of Senegal by taking into account existing local recommendations and references.
The main input parameters are:
> truck traffic characteristics: axle load, traffic intensity and aggressiveness,
> the characteristics of the roadway to be reinforced and its foundation. This information is the result of a prior testing program,
> the economic parameters of road policy such as the level of service, the maintenance cycles, etc,
> the usual reinforcement techniques.
The first step is to analyze the state of the art in Senegal from the available elements, such as the existing reinforcement studies, the traffic studies, the behavior of the pavements in service. On the ground, sections of roadways representative of the degraded routes of the road network will be chosen and examined. The analysis of the results will make it possible to model the structures in place and to calculate the reinforcement necessary to satisfy the fixed criteria. This process will lead to the development of a method of reinforcements design and classification of road sections in terms of required works.
The assignment is planned over a period of 20 months.
