Problems solved by technology

[0004] However, the above-mentioned scheme has the following defects in use: the original pavement material cannot be recycled, which wastes resources, and in the pavement maintenance process, only the method of compaction is used to compact the repair material, which is easy to produce a gap between the old and new pavement. Gaps, poor stability of combination of new and old road surfaces

Embodiment 1

[0025] A road construction and maintenance method, specifically according to the following steps:

[0026] S1: Construction preparation. After the inspection vehicle completes the inspection of the road surface, it determines the road surface maintenance area and draws the dividing line, removes the construction fence, assembles and builds the construction fence around the maintenance area, and places reflective lights on the incoming lane Warning signs, the distance between the reflective warning signs and the construction fence is 3m;

[0027] S2: Pre-cleaning, using a high-pressure fan to blast high-speed air to clean the surface of the maintenance area to remove floating dust and gravel on the road surface;

[0028] S3: Milling and maintaining the foundation pit. Use a cold milling milling machine to mill out the foundation pit in the maintenance area. The depth of the foundation pit is 10cm, and then perform secondary milling on the outer periphery of the foundation pit. ...

Abstract

The invention discloses a highway construction and maintenance method. Specifically, the highway construction and maintenance method comprises the following operation steps of S1, construction preparation; S2, pre-cleaning; S3, milling and maintaining of a foundation pit; S4, bitumenizing; S5, preparation of repair materials; S6, paving of the repairing materials; and S7, rolling. According to thehighway construction and maintenance method, construction fences and reflective warning signs are placed in a maintenance area, so that the construction safety of road maintenance personnel is improved; by milling the foundation pit and a transition groove in advance in the maintenance area and paving the foundation pit and the transition groove with a layer of asphalt, the stability of the connection between the repair materials and an original pavement structure can be improved, gaps between old and new pavements can be prevented, the pavement maintenance quality can be improved, and the original pavement materials are used as raw materials for pavement maintenance to realize the recycling of resources.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, and in particular relates to a road construction and maintenance method. Background technique [0002] In recent years, with the rapid increase of road traffic volume, the proportion of trucks has increased, and the phenomenon of overloading has been serious, resulting in various damages on the road surface, which not only seriously affected the transportation, but also caused huge economic losses. At present, road maintenance is more and more important to the normal operation of the road, and there are more and more maintenance methods. However, the road maintenance methods in the prior art are not only cumbersome, but also have a long maintenance cycle, which is not only time-consuming and laborious, but also affects traffic operation. It takes a long time and is not suitable for promotion and popularization. [0003] For this reason, the patent application number is CN201611194686.8,...
