Asphalt pavement roughness testing device

Abstract

The invention relates to an asphalt pavement smoothness detection device. The present invention effectively solves the problem that the existing road surface smoothness detection device is cumbersome to measure and the workload of the detection personnel is relatively large; the technical solution to be solved includes: the road surface smoothness detection device The detected road surface roughness information can be amplified correspondingly, so that the surveyor can clearly and intuitively see the road smoothness information, and through the cooperation of the intermittent transmission mechanism and the second transmission device set on the trolley, The detection device completes random inspection of road surface smoothness at specific distances, that is, realizes automatic detection of road smoothness information, greatly reduces the workload of detection personnel, and is easy to use and can be widely used.

Problems solved by technology

[0002] In modern highway construction, asphalt pavement is widely used in high-grade highways due to its short construction period, high driving comfort, low noise, and easy maintenance in the later stage. However, high-grade asphalt pavement requires high flatness. Inspectors need to follow up the inspection and acceptance in time, establish a database of asphalt pavement flatness, and provide a basis for subsequent construction and quality rectification. Asphalt pavement is prone to defects such as rutting, sinking and deformation, and wrapping, which will lead to a decrease in the smoothness of the road surface, affecting the driving experience of drivers and passengers, and even causing traffic accidents in severe cases;

[0003] Traditional road surface roughness detection devices include: uniaxial acceleration sensor, laser ranging sensor and odometer sensor, but the structure of traditional measuring device is complicated and the cost of use is high. It is easy to be damaged during the process, and once damaged, it will bring high maintenance costs;

[0004] Alternatively, traditional mechanical measurement methods are used to measure the flatness of the road surface, such as the 3-meter ruler method, but this method is relatively backward and the measurement efficiency is low. The operator needs to bow his head and bend over when measuring. The ups and downs change is not very large, and the road surface roughness information measured by the above method cannot amplify the real ups and downs of the road surface, that is, it is difficult for the surveyor to clearly and intuitively see the roughness information of the road;
