A kind of expressway pavement finishing method

Abstract

The invention belongs to the technical field of road maintenance, Specifically, the invention relates to an expressway pavement repairing method, the pavement restoration device in the method comprises a housing, an electric motor, a gear shaft, a driven gear, a rolling drum, a fixed shaft, a clutch, a transmission shaft, a pattern cam, and a perforated steel needle, wherein one end of the rollingdrum is rotatably installed on a side wall of the housing through the fixed shaft, a bevel gear is arranged on the other end face of the rolling drum, and the upper part of the bevel gear at the endof the rolling drum is meshed with the bevel gear at the lower end of the gear shaft to realize transmission; because the clutch is arranged at one end of the transmission shaft, and a group of pattern cams is uniformly arranged on the transmission shaft, The perforated steel heated on the rolling drum is used to punch holes on the damaged pavement, and the pavement is heated at the same time, andthe shrinkage can be realized; furthermore, the softened pavement is rolled by the rolling drum, the pavement is leveled, the pavement is repaired quickly, and the smoothness of the expressway is ensured.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, in particular to a method for repairing highway road surfaces. Background technique [0002] In high-grade highways, asphalt pavement is valued by countries all over the world for its well-known good performance. , no dust, small vibration, low noise, short construction period and easy maintenance and repair, etc., are widely used in expressways. With the development of highways in my country and the increase of traffic volume, rutting is the main form of damage to asphalt pavement. Rutting is the accumulation of permanent deformation in the vertical direction of the wheel track belt on the roadway under repeated wheel loads. When it is serious, there are usually bulging deformations on both sides. It is mainly caused by viscous flow of asphalt mixture, deformation of soil foundation and base course, and includes a certain degree of compaction and material wear. [0003] At present, t...

Problems solved by technology

[0003] At present, the repair of asphalt pavement ruts is mainly done manually. Due to the shortcomings of low work efficiency and high repair cost in manual repair of ruts, it brings great trouble to the repair of asphalt pavement ruts and affects the speed smooth road
