Description

Technical Field

[0002] As an important component of highway construction, the quality of highway pavement not only directly affects the service life of the highway, but also is related to the transportation safety of the highway. The structural depth of the pavement refers to: the structural depth of the pavement surface, formerly known as texture depth, is an important indicator of pavement roughness. It is the average depth of open pores in the uneven road surface of a certain area. It is mainly used to evaluate the macro-roughness, drainage performance and skid resistance of the pavement surface.

[0003] In order to detect the structural depth of the road surface, the existing devices usually use manual sand spreading method and electric sand spreading method to measure. The principle is to spread a known volume of sand on the measuring point of the road surface to be tested, measure the area covered by the spread, and the ratio of the volume of the sand to the average covered area is the structural depth. However, when the staff are measuring, the manual sand spreading operation is relatively inconvenient. At the same time, the existing devices cannot clean the ground before spreading the sand, which affects the accuracy of the detection. At the same time, manual sand removal is required during the sand spreading detection, which increases the workload of the detection personnel. At the same time, some existing devices cannot detect the strength of the road surface while detecting the structural depth of the road surface, which reduces the efficiency of the road surface detection.
