Asphalt mixture thickness measuring device

The utility model relates to the technical field of road construction, in particular to an asphalt mixture thickness measuring device which comprises a steel pipe, a connecting block is fixedly arranged on the side wall of the steel pipe in the length direction perpendicular to the steel pipe, and a graduated scale is arranged at the end, away from the steel pipe, of the connecting block in the length direction parallel to the steel pipe. A penetrating hole is formed in the top wall of the connecting block, and the graduated scale is slidably connected into the penetrating hole in the length direction of the steel pipe. When the thickness of asphalt is measured, the steel pipe and the graduated scale are firstly placed on the asphalt pavement, then the steel pipe is moved along the length direction of the steel pipe to the bottom of the asphalt pavement, the steel pipe is abutted against the bottommost part of the asphalt street lamp, and then a worker reads the position of the connecting rod on the graduated
