Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement thickness detection technology, specifically to an asphalt pavement thickness detection device for traffic engineering. Background Technology

[0002] Highways are built to make travel more convenient. Nowadays, when constructing highways, a layer of asphalt is laid on top of the concrete. Asphalt has waterproof properties, which can prevent water accumulation on the road surface after the concrete is damaged. After the asphalt is laid, it needs to be laid to a certain thickness to achieve the desired effect. After the asphalt is laid, the thickness of the asphalt on the highway needs to be tested in sections to determine whether the thickness of the asphalt paving meets the standards.

[0003] Currently, in the loose-lay thickness testing of asphalt concrete pavement, a screwdriver is usually inserted into the asphalt concrete first, and then a steel ruler is used for measurement. However, since the temperature of the asphalt is very high after it is laid, the screwdriver is also very hot after insertion, which can easily cause burns to technicians. This is not conducive to measurement and is prone to errors. In addition, after removing the screwdriver, it is also necessary to use a ruler to measure the depth inserted into the asphalt. The operation steps are cumbersome and it is not convenient to obtain accurate measurement data intuitively.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
