The invention provides a highway pavement evenness measuring system. The highway pavement evenness measuring system comprises a measuring device, a first gantry framework, a first scanning device and a second scanning device, wherein the first gantry framework is arranged on a highway pavement, and the first scanning device and the second scanning device are arranged on the left side and the right side of a vehicle respectively. A first position label and a second position label are arranged on the left side and the right side of the first gantry framework respectively, the first scanning device is used for scanning the left side of the first gantry framework and sending scanned first image information to the measuring device, the second scanning device is used for scanning the right side of the first gantry framework and sending scanned second image information to the measuring device, and the measuring device is used for measuring the evenness achieved when the vehicle passes through the highway pavement according to the first image information and the second image information. According to a highway pavement evenness measuring method, it is unnecessary that an evenness measuring instrument is used for regularly detecting the highway pavement, the operation is simple, and timely measurement can be achieved.
Description
technical field [0001] The invention relates to the field of highway pavement performance detection, in particular to a highway pavement smoothness measurement system. Background technique [0002] With the rapid development of the transportation industry, the smoothness of highway pavement is closely related to people's travel. In order to obtain a pavement with good flatness, it is usually necessary to conduct a vehicle acceleration loading test on the paved road surface, and during the accelerated loading test process, the road surface is measured regularly with a flatness measuring instrument to determine the flatness of the road surface. However, at present, the method of regularly measuring the road surface with a flatness measuring instrument is complicated to operate, and it is impossible to measure the road surface flatness in time. Contents of the invention [0003] The invention provides a highway pavement smoothness measurement system to solve the problems of ...
