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 evaluated reinforced subgrade soils in a loading conditions that are as similar as possible to fields is warranted .
The purposed of this research is to investigate the life cycle improvements of pavements when they are reinforced by geotextiles and a geonet , Four pavement test groups were constructed to simulated 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 repeated loading is more realistic than C.B.R. Also , geonets perform better than geotextiles when employed as reinforcement.
