| Abstract: | The results of dynamic modulus comparison tests are processed and analyzed by ASTM-E691 and robust statistical method.In order to explore the causes of differences in experiment results,the void ratio of the specimens is analyzed and compared.The results show that the size and dispersion of void ratio directly affect the accuracy of the dynamic modulus test results. |
