Mechanical characteristics of Geogrid reinforced lime/cement granular soils

Reinforcement of stabilized bases has been considered to be a modern solution to the problems caused by soft and problematic subsoil strata. The application of lime/cement treated geogrid reinforced soils can be cited as a method. However, the addition of reinforcement alters the mechanical properties of stabilized soils significantly. In this study, a series of unconfined compression tests have been carried out to investigate the effects of stabilized soil types, specifically, changes in properties that geogrid reinforcement imposes on treated materials. The results show, that when the maximum diameter of treated materials are reduced from 19 mm to 9 mm, the geogrid reinforcement functions better in combination with lime/cement treatment.
