Analysis of Load-Settlement Relationship for Unpaved Road Reinforced with Geogrid
Taking into account of the model test results, the surface settlement of an unpaved road reinforced, to improve its safety, with geogrid placed at the granular fill-soft earth interface is analyzed under wheel load. The relationship between the surface settlement and the contact pressure of tire is derived, which can be used to estimate the bearing capacity corresponding to a given surface settlement for a given geogrid-reinforced unpaved road, or to calculate the proper thickness of the granular fill layer and the necessary tensile strength or tensile modulus of the geogrid for such a road.
