G., Hino, T. and Harianto, T.題名：Lithostab as technique for improving the geotechnical performance of a lateritic soil in road construction発表情報：Journal of Civil Engineering and Architecture 巻: 16 ページ: 425-430キーワード：概要：This article focuses on a technique for shallow mechanical improvement of soil which deals with the utilization of crushed granite mixed in a certain percentage with lateritic soils during road construction in Burkina Faso. Lithostab is the simplified name for litho-stabilization, a technique for improving laterite by adding crushed granite that increases the CBR (California bearing ratio) of that material for being used in road construction. Class 0/25 of crushed granite added to a laterite in our case gives good performance in terms of CBR. Indeed, the CBR index which was initially 48 at 98% of the OMP (optimum modified Proctor) goes to 88. And from 84 at 98% of the OMP, it goes to 128 for 30% of class 0/25 of crushed granite added. This means that class 0/25 of crushed granite provides better CBR index to that material when it is incorporated at 30%. So, lithostab is an easy to implement eco-friendly material for road construction because of the utilization of local materials. Then, it contributes to the protection of the environment in the sense that its production does not require a lot of energy and does not release large quantities of carbon dioxide into the atmosphere.抄録：This article focuses on a technique for shallow mechanical improvement of soil which deals with the utilization of crushed granite mixed in a certain percentage with lateritic soils during road construction in Burkina Faso.
