Test Research of Geogrid Reducing Pavement Rutting on Soft Foundation
The interior prototype rutting test is designed to research the effect of geogrid on reducing rutting. Three models are studied, which include unreinfored, Telegrid JBS20 and Tensar SS30. The change trend of rutting and the influence of differential structure geogrid on rutting are analyzed to evaluate the effect of geogrid on reducing rutting. The results of the tests prove that the geogrid reduce pavement rutting on soft foundation effectively, SS30 with higher node intensity and rigidity obviously exceeds JBS20 with higher tensile strength on the effect of reducing rutting, and the effect on reducing rut is not very good by improving tensile strength of geogrid.
