The present study is inscribed within the framework of the valorization of local materials in road construction techniques. Identification tests were carried out on silty sand. The results obtained showed that the content of fine particles, the CBR at 95% Modified Optimum Proctor and the plasticity index of the samples studied were respectively 15.25%, 31 and 16%. From the results obtained, it is evident that these materials cannot be used in their natural state for the construction of road infrastructures and sporting tracts. A proposal for the correction of these materials by adding 2%, 3%, 4%, 6% and 8% of lime was carried out. Test results carried out on samples of the modified materials showed that, by adding 4% lime and taking construction dispositions, these materials are good for usage as base course in road construction and as surface course in sporting tracts.
