Maintenance construction method for high-toughness mute thin overlay of urban road and bridge

Abstract

The invention discloses a maintenance construction method for a high-toughness mute thin overlay of a urban road and bridge, and relates to the technical field of road construction, and the method comprises the following steps: preparing materials: preparing asphalt concrete production and construction temperature meeting setting requirements; processing an expansion joint, specifically, cleaning sundries in the expansion joint, pre-burying a traction rope in the expansion joint, and performing anti-bonding treatment on the traction rope; pre-lifting the inspection well: marking the inspection well, and lifting the well synchronously; performing synchronous pavement paving: performing synchronous construction on a bonding layer and an asphalt concrete pavement layer to form a high-toughness mute thin-layer overlay; processing an inspection well after paving, specifically, filling gaps around the inspection well with materials, and scraping out thin-layer materials of the inspection well; performing synchronous rolling treatment; after paving and rolling are completed, processing the expansion joint, and pulling and cleaning the traction rope in the expansion joint; and opening traffic. The construction efficiency is improved, meanwhile, the anti-cracking, anti-seepage and anti-sliding effects are achieved after the pavement is formed, the flatness is improved, the driving noise is reduced, and the attenuation speed of the road use function is delayed.

Description

technical field [0001] The application relates to the technical field of road construction, in particular to a construction method for maintenance of urban road bridges with high-toughness and quiet thin-layer overlays. Background technique [0002] With the rapid development of cities and the improvement of people's daily travel requirements, the convenience and refined construction of municipal infrastructure have become increasingly prominent. After urban bridges and roads are completed and put into use, they must bear the effect of traffic load and be exposed to wind blowing. , Rain, ice, snow, and sun exposure will inevitably lead to the decline of its use function and driving service quality. It is likely to be damaged before the maintenance period is reached, and serious traffic accidents will be caused. In order to keep it in good condition during its service life, it is necessary to adopt appropriate refined construction and maintenance in a timely manner. [0003]...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present application solves the traditional road surface micro-surfacing process in the prior art by providing a high-toughness and quiet thin-layer overlay maintenance construction method for urban road bridges. Although the construction time can be shortened, the noise after construction is relatively large and the driving is comfortable. In order to improve the construction efficiency and at the same time achieve anti-cracking, anti-seepage and anti-skid effects after the pavement is formed, improve the flatness, reduce driving noise, and delay the attenuation speed of road use functions
