Geogrid Reinforced Lime Cement Treated Granular Soils

Abstract:

Construction on problematic and soft soils has always been considered a challenging task by the geotechnical engineers. Such soils can be treated with traditional lime and cement stabilization. However in some cases using geogrid reinforced lime and cement treated materials can be very effective, especially in case of seismic or dynamic loads. In this research, a series of laboratory testing has been carried out to investigate mechanical properties of lime and cement treated granular materials with and without geogrid reinforcing layers. The results of the unconfined compressive tests show that geogrid reinforcement improves the ductility of the treated materials. However, it would not develop the compressive strength in many of used mix Designs. The investigations reveal that the mix design for lime and cement treatment must be selected accurately by considering the natural beds conditions to achieve the best possible results from stabilization procedure.
