摘      要：In tropical areas,palm oil production generates significant amounts of waste,including palm kernel *** use of this waste in the civil engineering sector,presents a very challenging *** the present study,the production of lateritic soil(A-2 in GTR classification and A-7-6(9)in HRB classification)reinforced with palm kernel shells is *** order to improve their performances,these materials are mixed using the Fuller’s parabolic ***,experimental tests are used to characterize the physical and mechanical geotechnical properties of the lateritic *** characterizing the matrix(i.e.,lateritic soil)and the inclusions(i.e.,palm kernel shells)in their natural state,it is found that Avrankou’s lateritic soil has a high level of fine particles(56.6%),high plasticity(PI=21%)and low lift(ICBR=17%);which makes it unusable in the pavement *** also prove that the mixture composed of 39%of lateritic soil volume and 61%of PKS with a CBR index equals to 30 and the mixture composed of 45%of lateritic soil,40%PKS and 15%of lagoon sand with a CBR index equals to 41 can be used as sub-base layer for roads for low and medium traffic,respectively.
