This set of experimental equipment used to study the impact of road alternating load on highway subgrade. Through the design of the experimental device on the different locations of the subgrade to apply alternative loads, to find the impact of different loads on the subgrade. The experiment device is composed of power transmission system, hydraulic system and control system. The direct current motor provides the power source for the experimental device, and the hydraulic device is applied to the experimental roadbed, and the pressure sensor and the displacement sensor in the roadbed can monitor the deformation of the roadbed in real time. In the design of the experimental device, the ANSYS analysis software is used to carry out the finite element analysis of some important parts of the experimental device, and through the analysis of the results of the optimization design of the parts. Through the experiment device, the subgrade applied alternating load experiment, obtain road of stress and strain of; simulated pavement under alternating load by means of finite element analysis and draw analysis results. The results obtained by the experimental device can roadbed construction and maintenance reference opinions are put forward.
