Highway engineering compression resistance experiment device

The utility model relates to the technical field of highway engineering, in particular to a highway engineering compression resistance experiment device which comprises a base plate, a hydraulic cylinder is fixedly connected to the middle of the base plate, vacuum pumps and suckers are fixedly connected to four corners of the base plate, and a rotating plate with a dust collection fan is rotatably connected to one side of the base plate. The road surface detection device has the advantages that pressure is applied to the road surface through the hydraulic cylinder, the output end of the hydraulic cylinder is provided with the round corner, so that the edge of the hydraulic cylinder is prevented from leaving indentations on the road surface when the hydraulic cylinder detects the road surface, the damage to the road surface during detection is reduced, the shielding plate is arranged on the outer side of the hydraulic cylinder to surround a test point, and the detection accuracy is improved. When the road is c
