Road surface flatness testing vehicle and method

Abstract

The invention belongs to the technical field of expressway construction, in particular to a road surface flatness testing vehicle and method. The road surface flatness testing vehicle includes a testing vehicle body, and the testing vehicle body is internally provided with a road vertical track waveform acquisition device; the road vertical track waveform acquisition device includes a vertical sliding mechanism and a waveform recorder. The upper and lower ends of the vertical sliding mechanism are provided with a track recording touchpen and a ground touching device respectively. The track recording touchpen and the ground touching device move up and down synchronously, the track recording touchpen makes contact with a panel screen of a waveform recorder, and the ground touching device makes contact with a to-be-tested road surface. In order to solve the problems that the '3m ruler' method adopted by a traditional process for road surface flatness detection is greatly influenced by human factors, a lot of labor and material resources are needed when a detection route is longer, the detection efficiency is low and the detection results are not accurate, the purpose of improving theroad surface flatness testing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of expressway construction, and in particular relates to a road surface smoothness detection vehicle and a detection method. Background technique [0002] With the rapid development of my country's economy, the level of traffic network planning is getting higher and higher, and the geographical scope is getting bigger and bigger. With the rapid development of a large number of traffic infrastructure construction such as expressways, people's requirements for driving comfort are getting higher and higher. . [0003] In expressway construction, roughness refers to the deviation value of the unevenness in the longitudinal direction of the road surface, and is one of the main technical indicators for evaluating the quality of the road surface. The impact force and service life have a direct impact. In the inspection and acceptance of road smoothness, the current method determines the detection frequency accordi...
