Abstract

In a previous research, the C.B.R. test has proved to be useful in evaluating reinforced subgrade soils [1] . When testing specimens after soaking with and without reinforcement one can come up with two values of C.B.R. for comparison. However, the need to evaluate reinforced subgrade soils in a loading conditions that are as similar as possible to field is warranted.
The purpose of this research is to investigate the life cycle improvements of pavements when they are reinforced by geotextiles and a geonet. Four pavements test groups were constructed to simulate the field conditions as possible. One group was the control sections, and the other three were reinforced with geosynthetics. Simulated traffic repeated loads were applied and the vertical deformation of tested pavement surface was measured at the edge of loading plate. It is concluded that testing relatively larger scale models by respeated better than geotextiles when employed as reinforcements.
