Abstract: 

In order to achieve an adequate layout of the various roadway components of the project for the construction of the second Wouri bridge, with the aim of limiting the short term degradation due to the joint action of weather conditions and the intense traffic of heavyduty vehicles, a study has been carried out and results presented on some parameters, ranging from geotechnical tests on soil Shrinkage/Swelling, materials bearing capacity, water content rate and other properties linked to the mechanical behaviour, that have an influence of the compacting of materials used in the project. Then a computer modeling was carried out on the layoutof ALIZE-LCPC roadways in order to illustrate the influence of the variation in the thickness of layers of the runway on the lifespan of the latter. In the final analysis, results of the Compacting Trial area carried out on the Bituminous Graves ≥ 89% max max equal to94.6%,in conformity with the Project’sSpecial Technical Specifications, with norms NF P 98-150-1 and NF P 18545,and with the Control Plan of VRD – SOG – PES - EXE 6101.
