PARTIALLY RESEARCH MECHANICAL TREATMENT OF GRANULAR BASE COURSE MATERIAL IN KHARTOUM STATE

Abstract

This research is about the mechanical treatment of base course material. The base course in Khartoum state is facing a problem of scarcity. Nowadays, it is hard to find base course materials comply with the specifications for constructing roads. Therefore, some of the materials supplied from quarries to constructional locations need to be treated. There are several ways and methods of soil treatment and stabilization but in this research, the soil treated by the mechanical stabilization. The purpose of treatment is for improving of soil properties. This method is so simple and easy as well as the good results obtained. Moreover, it is not costly, comparing to other soil treatment methods such as the chemical stabilization. In the research, three samples were collected from materials supplied to construction locations from quarries. For treating the samples, percentages of sand, natural gravels and crushed stone were added in many trials, so as to improve the engineering properties of the material and to conform to the requirements. The results were magnificent and base course materials conformed to the specifications were obtained which could be used in roads construction as base materials. From the research, it is obvious that the subbase material could be treated to act as base course materials.
