Rapid repairing method for asphalt pavement

Abstract

The invention discloses an asphalt pavement rapid repairing method which comprises the following steps: delineating three boundary lines according to a damaged part of an asphalt pavement, and delineating a punching circle between two adjacent boundary lines; punching a round hole in the punching circle; cutting the asphalt pavement along different boundary lines, milling the asphalt pavement in the boundary lines, and digging the waste asphalt mixture cut and milled for three times; a new asphalt pavement material is prepared from the waste asphalt mixture; and emulsified asphalt is poured into the round holes, and the prepared new asphalt pavement material is fully paved in the boundary line and is compacted. The multiple boundaries are arranged between the damage repair area and the undamaged pavement, and the grooves with different heights are excavated between the adjacent boundaries, so that a transition area is formed between the undamaged pavement and the damage repair pavement, the structural strength difference between the newly-built pavement and the old pavement is not too large, and it is guaranteed that the bonding strength of the newly-built pavement and the old pavement is good.

Description

technical field [0001] The invention relates to the field of rapid repair of road surfaces. More specifically, the present invention relates to a quick repair method for asphalt pavement. Background technique [0002] Highway is an important symbol to measure a country's economic strength and modernization level, and it has an obvious role in promoting national economic and social development. With the rapid development of my country's highway industry, the task of highway maintenance is becoming increasingly arduous. And my country's highway is mainly based on asphalt pavement, and asphalt pavement is widely used in road engineering, from country roads to urban roads, from tertiary roads to expressways, all generally adopt. However, due to the differences in the asphalt concrete material itself, as well as the design, construction and maintenance level and the external environment, the asphalt pavement often has cracks, looseness, subsidence, cracking, oil flooding, ruts,...

AI Technical Summary

Problems solved by technology

However, due to the differences in the asphalt concrete material itself, as well as the design, construction and maintenance level and the external environment, the asphalt pavement often has cracks, looseness, subsidence, cracking, oil flooding, ruts, potholes and other diseases.

The emergence of these diseases has seriously affected the driving speed and driving safety, and shortened the service life of asphalt pavement, resulting in the shortening of the service life of the pavement.

However, the existing repair methods are labor-intensive, time-consuming and labor-intensive, and cannot quickly and effectively repair the pavement, and the bonding strength between the newly repaired pavement and the old pavement after repair is poor, resulting in a short service life of the repaired pavement
