Abstract
The present work investigates the behavior of unpaved road overlying soft clay layer reinforced with single layer of geogrid placed at the subgrade/subbase interface. A laboratory model is reinforced with two different types of geogrid and subjected to repeated load using Wheel Tracking Apparatus. Unreinforced and reinforced subbase over soft subgrade were constructed in a large testing box (500mm*500mm*750mm). The test results show that for the same rutting value (75mm); the using of geogrid reinforcement layer produces an increase in number of passes and stress distribution angle and a decrease in displacement on the soft subgrade surface on the reinforced models as the equivalent unreinforced one.
