Asphalt painting thickness detection tool

The utility model provides an asphalt brushing thickness detection tool, which relates to the technical field of construction tools and comprises a measuring component and a fixing component. The measuring component is inserted into the asphalt layer, the fixing component is placed on the surface of the asphalt layer, the measuring component can slide along the surface of the fixing component, and when the measuring component is inserted into the asphalt layer, the scale marks integrally move downwards, so that the measuring component can be matched with the fixed pointer to test whether the asphalt coating thickness meets the requirement or not, and the uniform asphalt coating thickness is ensured; the technical problems that in the prior art, due to the fact that the thickness of asphalt is not uniform easily in the brushing process, leakage of the deformation joint can be affected, a large amount of manpower and material resources need to be consumed in later repair, and meanwhile large hidden danger exist
