摘要: Nowadays, the question of the availability of good quality materials is increasingly raised in road projects. This has led us to techniques for improving the performance of materials that can be used in road layers. Cement and lime treatment is a well-known technique for improving materials in road construction. The test is done by adding a small amount of cement or lime to the material to be improved. This amount is determined at various percentages in order to obtain a good result. To carry out our study, it is necessary to study the raw material to see if it meets the standards, otherwise it must be improved. Indeed, for a material to be used in road layers, a minimum bearing capacity of 80% to 98% of OPM is required. Also, in order to understand the evolution of the CBR bearing capacity, we will make our materials suitable for road construction by mixing them with lime and cement.
