Device and method for detecting thickness of mortar on cement concrete pavement of airport

The invention provides an airport cement concrete pavement mortar thickness detection device and method, and relates to the technical field of airport engineering, the airport cement concrete pavement mortar thickness detection device comprises a cutting ring, a plurality of laser ranging units and a terminal, the cutting ring is provided with a tooth part, the laser ranging units are detachably connected with the cutting ring, and the laser ranging units are electrically connected with the terminal. According to the mortar thickness detection device, the tooth parts are arranged on the cutting ring, so that the mortar thickness detection device is easily inserted into concrete and more easily sinks on a road surface, and it is ensured that the mortar thickness detection device can stably make contact with a mortar layer during measurement. Then, a plurality of laser ranging units are arranged to measure the thickness of the mortar from different positions so as to improve the accuracy and reliability of meas
