This instrument is suitable for testing and continuously collecting the depth of road surface structures under normal driving conditions such as new and renovated airports and ports, road surface engineering quality acceptance, and no serious damage, disease, and no accumulated water, snow, mud, etc. However, it is not suitable for measuring the depth of cement concrete road surfaces with groove structures

Texture Depth (TD) is an important indicator for evaluating the anti-skid performance, drainage capacity, and driving comfort of road surfaces. The laser construction depth tester is a non-contact device based on the principle of laser ranging, used to quickly and accurately measure the macroscopic texture and microscopic construction depth of road surfaces. Compared to traditional methods such as sanding, it has advantages such as high efficiency, automation, and data traceability.
