The invention relates to the field of highway engineering, in particular to pavement thickness detection equipment for highway engineering. The equipment comprises a supporting base, wherein universal wheels are fixedly connected to the bottom of the supporting base, a driving motor is fixedly connected to the inner wall of the supporting base, a driving worm is fixedly connected to an output shaft of the driving motor through a coupler, and the top of the supporting base is movably connected with a first connecting shaft. According to the pavement thickness detection equipment for the highway engineering, the universal wheels are arranged, so that the supporting base can be conveniently moved, and the detection position can be conveniently adjusted. Meanwhile, the thickness of different positions of a pavement can be conveniently and synchronously detected through a detection dial indicator in the moving process, so that the accuracy of thickness detection is improved, the problem that the pavement thickness detection is not accurate enough is solved, the labor consumption of detection work is reduced at the same time, the operation convenience is improved, the working requirements of people are met, and the equipment is worthy of popularization and application.
