Background

Existing highway pavements are generally cement pavements and asphalt pavements. Along with the rapid development of traffic industry in China, the requirements on highway performance are higher and higher, the road surface flatness is one of the most important indexes for evaluating the highway performance, and the highway standard requirements are that the gap height between the road surface and the road surface exceeds 3mm when the road surface is detected by using a 3-meter ruler, so that the road surface is unqualified. The flatter the road surface is, the smaller the vibration and impact are when the automobile runs, the smaller the resistance of running is, and meanwhile, the higher the running comfort is; the road surface with good flatness not only ensures that the automobile can run at a higher speed, but also reduces the damage of parts of the automobile and reduces the fuel consumption and the tire wear; importantly, the unevenness of the road surface can even threaten the driving safety. However, in road pavement construction, the pavement flatness is disqualified due to influences of weather, equipment, manpower or base layers, construction joints and the like. In the road which is already in use, the road surface flatness is poor due to the settlement of roadbeds, uneven wear, rutting and the like.
