16 Ref.; pp 145-155. A series of monotonic and repeated load resilient modulus triaxial tests were conducted on unreinforced and geogridreinforced crushed limestone samples to evaluate the effects of the stiffness, location, and number of geogrid layer/s on the strenght properties and stress strain response parameters of those samples. Five different types geogrids were used, and for each geogrid type, four different cases selected to assess the benefits of geogrid improvement namely, Es1%, Es2%, and USS. Statistical analyses were conducted on the results using ANOVA and post ANOVA LSM. The results of these analyses indicated that generally geogrid with higher stiffness moduli exhibited greater improvement. In additional, double layers had always the maximum improvement, while the minimum benefit was observed for single geogrid layer palced at the sample mid-height. The cyclic triaxial test result were used to determine resilient moduli for the different samples. These result showed that the geogrid reinforcement did not enchance the resilient properties of the reinforced samples.
