Research on the cumulative strain rules of rubber mixed sand under traffic load

Vehicle load traveling on the road is a complex stochastic dynamic loading process. For a point on the road, this is a process of loading and unloading. The procedure can be viewed, similarly, as a sinusoidal wave model. This paper will study the axial cumulative strain change law of rubber mixed sand samples under traffic load. When using the GDS dynamic triaxial test, the sine function waveform is used as the load to simulate the dynamic stress conditions under the traffic load. Then the conclusion that rubber mixed sand settlement is significantly smaller than pure sand is obtained, and the class “spring” theory of rubber sand test sample is proposed. Period is used in engineering practice.
