Road traffic engineering pavement quality detection device

The invention relates to a road traffic engineering pavement quality detection device, which comprises a shell and a paving plate, the lower end of the shell is provided with a paving hole, the shell is internally provided with a first motor, the output end of the first motor is provided with a turntable, the surface of the turntable is radially and slidably connected with a moving block, and the moving block is slidably connected with the paving plate. A driving device for driving the moving block to slide in the radial direction of the rotating disc is arranged on the surface of the rotating disc, a connecting rod is rotationally connected to the moving block, a vertical rod is arranged at the end of the connecting rod, and the paving plate is arranged at the lower end of the vertical rod; the dry sand is gradually paved outwards by controlling the circular motion track of the paving plate, and finally the circular paving surface is formed, so that the measurement of the radius of the paving surface is more
