DESIGN, CONSTRUCTION AND PERFORMANCE OF SILTY SAND STABILIZED ROAD BASE

Silty sand is plentiful while rock source is scarce in Northeastern Thailand. This research study is emphasized over stabilization of silty sand for being used as base course material instead of crushed rock. It was found that only 3 percent cement could improve the quality of local silty sand to meet the criteria for employing the above purpose. Silty sand mixed with 3 percent cement and 3 percent emulsion was found with having stability high enough to serve as base course without excessive reflected crack. A test road was constructed to check the performance of some economic mix proportions between silty sand and additives under the actual traffic condition. From a long-term evaluation for more than 7 years, it could be concluded that all sections of the test road exhibit good performance. In conclusion, it could be stated that silty sand stabilized with 3 percent cement, both with and without emulsion, could replace crushed rock for the base course construction in Northeastern Thailand.
