[0002] In recent years, with the rapid development of my country's transportation industry, the traffic volume is large, the speed is fast, and the load is heavy, especially putting forward higher requirements on the mechanical properties and stability of bridge and highway subgrades. Now new materials have been applied in bridge subgrade engineering. Common bridge subgrades use many types of new materials. The road performance characteristics of bridge subgrades of different materials are significantly different. In order to compare the road performance of different types of subgrades, long-term observation and performance comparison are required. There are various test platforms, but there is no device on the test platform to clean and crush the subgrade materials of the completed test bridges. When the test needs to be repeated many times for the accuracy of the test, the subgrade materials that have been tested are cleaned.
