Repair method of expressway pavement

Abstract

The invention discloses a highway pavement repair method, comprising: identifying the type of pavement damage; wherein, the types of pavement damage include: bulge, collapse and crack; corresponding pretreatment is performed on the damaged position according to different types of pavement damage; According to different types of damage, the bottom layer of the pavement at the damaged position should be repaired accordingly; for the pavement surface repair: according to the different types of pavement damage, the corresponding repair of the pavement surface at the damaged position should be carried out. It implements different repair methods according to the types of pavement damage, which effectively improves the quality of pavement repair and prolongs the service life of the pavement after repair.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a method for repairing highway road surfaces. Background technique [0002] In recent years, with the continuous development of the national economy, the number of automobiles has increased year by year, and the logistics industry and the transportation industry have developed rapidly, which has led to an increase in the traffic flow of the expressway, especially the increase in overweight and overweight vehicles. The transportation capacity caused great pressure, resulting in serious wear and tear on the expressway. At the same time, with the increase of the service life of the road, the deformation of the subgrade of the road surface also made the damage of the expressway more frequent. However, due to different reasons, the road surface damage The manifestations of the road surface are not the same. Common road surface damages include pavement bulging, subsidence, and...

Problems solved by technology

[0002] In recent years, with the continuous development of the national economy, the number of automobiles has increased year by year, and the logistics industry and the transportation industry have developed rapidly, which has led to an increase in the traffic flow of the expressway, especially the increase in overweight and overweight vehicles. The transportation capacity caused great pressure, resulting in serious wear and tear on the expressway. At the same time, with the increase of the service life of the road, the deformation of the subgrade of the road surface also made the damage of the expressway more frequent. However, due to different reasons, the road surface damage The manifestations of the road surface are not the same. Common road surface damages include pavement bulging, subsidence, and cracks. In the existing pavement repair methods, the damaged area is basically broken and cleaned, filled with repair fillers, compacted and maintained to restore traffic. , however, this stereotyped repair method does not allow the pavement to obtain the most appropriate repair method according to the type of damage, and then makes the repaired pavement prone to damage again in a short time. It can be seen that the development of a road surface The method of repairing the pavement according to the different types of damage to improve the service life of the pavement after repair has far-reaching significance for the development of road traffic
