| Abstract: | Many data are accumulated on the physics mechanical properties of weathered granite, but the data of its dynamic behaviors are poor. According to the dynamic subgrade characteristic subjected to the vehicle loading, the tests of modulus of resilience under repeated loading, dynamic strength and dynamic strain are studied in laboratory for expecting to gain the dynamic behaviors of weathered granite soil. |
