Problems solved by technology

[0004] Existing detection of road surface roughness is generally through the instrument sliding on the road surface to determine the anti-skid ability of the road surface, or using a test car to test the friction coefficient of the road surface; however, the sliding of the testing instrument and the driving detection of the test car on the road There is a single situation, and in the actual process, the track of the vehicle wheel is unpredictable, it is difficult to directly and accurately measure the road surface roughness

Abstract

The invention discloses a road engineering pavement quality detection device, which belongs to the field of pavement detection equipment. By adopting the path movement process in which the detection contact is attached to the road surface and performs multi-directional rotation, the detection contact can perform a large-scale, multi-directional detection of the road surface in the area. During the detection process, through the mutual contact and extrusion of the outer bag and the inner bag and the balloon, not only the automatic side shift and deviation of the detection contact at the peak position of the road surface is realized, but also the detection contact is effectively guaranteed. At the same time, the peak road conditions are also reflected on the pressure sensor. By combining the detection results of the detection contact and the pressure sensor, the change of the road surface roughness can be directly and accurately displayed. Compared with the prior art, the detection method of the present invention has The actual complex and changeable use environment is more suitable, making the detection results more accurate.

Description

technical field [0001] The invention relates to the field of pavement detection equipment, in particular to a pavement quality detection device for highway engineering. Background technique [0002] After highway construction, highway supervisors need to inspect the construction quality of the highway. The inspection items include road surface smoothness, road surface permeability, road surface roughness and so on. Quality inspection has played an important role in ensuring the quality of highway engineering construction, improving the quality of road use and investment efficiency, and will continue to play an irreplaceable role in future engineering construction and management. [0003] The most direct contact with the road surface is the vehicle tire. Among them, the road surface roughness has a direct impact on the sliding resistance, deformation and wear of the vehicle tire during driving, and affects the safe driving of the vehicle. Therefore, it is very important. [...
