Asphalt pavement flatness detection device

Abstract

The invention relates to an asphalt pavement flatness detection device. The problems that an existing pavement flatness detection device is tedious in measurement and large in workload of detection personnel are effectively solved. According to the technical scheme, the detected pavement flatness information condition can be amplified in a corresponding proportion by the device so that measurementpersonnel can clearly and visually see the flatness information of the pavement; and through cooperation of an intermittent transmission mechanism arranged on a trolley and a second transmission device, the detection device completes spot check and detection of the pavement surface flatness at specific intervals, namely, automatic detection of pavement flatness information is achieved, the workload of detection personnel is greatly reduced, and the device is convenient to use and can be widely applied and popularized.

Description

technical field [0001] The invention relates to the technical field of road construction detection, in particular to an asphalt pavement smoothness detection device.

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;
