[0002] A highway is generally composed of a roadbed and curbs, with drainage ditches formed between the curbs and the roadbed. After a highway is built, it is usually necessary to conduct a compression test on the roadbed to determine the maximum load capacity allowed by the highway, to avoid damage to the roadbed caused by vehicle overload, and to affect the subsequent use of the highway. The roadbed test usually fixes the stamping machine frame on the roadbed, and then uses the stamping head to perform single-point repeated stamping tests on the roadbed surface. The degree of deformation at the stamping point of the roadbed is used to observe the degree of force on the roadbed.

It is easy for the debris and power structure generated during the test to cause accidental injuries to the surrounding test personnel, thus posing a safety hazard to the testing work.
