Road basal pelletized material mixture resilient modulus indoor test method and device

The invention discloses a road base gravel mixture rebound modulus indoor test method. The steps include that first, test materials are added in a test tube. The second step is sample static pressure molding. The third step is to arrange a miniature bearing plate on the surface of the sample. The fourth step is loading, unloading and rebound modulus test implementation. The fifth step is to read deformation amount. The sixth step is to take a rebound modulus value. The seventh step is to process test data. And the rebound modulus value is obtained. The invention is characterized in that firstly the test tube value taken formula is that the ratio of the diameter of the test tube to the maximum grain size=D/dmax. And the ratio is larger than five. Secondly, the diameter of the bearing plateis three times of the gravel maximum grain size. Thirdly, the mode of the rebound modulus test is that a jack is arranged on the bearing plate. The rebound modulus test is implemented through loadingand unloading with a react
