Problems solved by technology

[0003] After the asphalt pavement is put into use for a period of time, there will be situations such as water resistance damage and insufficient surface anti-skid ability. Although the traditional emulsified asphalt fog seal technology can solve the problem of water damage resistance, it does not significantly improve the road surface skid resistance. , and micro-surfacing can solve the problem of insufficient anti-skid ability of the road surface, but the noise is large, the driving comfort is poor, and the effective time of the above two traditional maintenance technologies is short

Abstract

The invention discloses an aqueous resin modified asphalt pavement maintenance material and a preparation method thereof. The aqueous resin modified asphalt pavement maintenance material is prepared by the following steps: uniformly mixing resin, an oil content, asphalt and an emulsifier, adding water into the mixture for emulsification, then adding aqueous carbon black color paste, fillers, fineaggregates and coarse aggregates into the mixture and uniformly mixing. When in application, the surface layer of an asphalt pavement is coated with the aqueous resin modified asphalt pavement maintenance material by spray coating, scrape coating or roll coating, so that the skid resistance and the water damage resistance of the asphalt pavement can be improved, therefore, the service life of a road is prolonged.

Description

technical field [0001] The invention relates to the field of asphalt pavement maintenance materials, in particular to a water-based resin modified asphalt pavement maintenance material and a preparation method thereof, and belongs to the technical field of asphalt pavement fog sealing layer and anti-skid thin layer overlay material. Background technique [0002] Asphalt pavement is the main structural form of highway and urban road pavement in our country. With the development of our country's national economy, the highway construction is advancing by leaps and bounds. The focus of my country's highway construction will shift from construction to construction and maintenance simultaneously, and maintenance will be the main focus. As the asphalt pavement of the highway is used for a long time, under the repeated action of traffic load and the erosion of natural environmental conditions, various damage phenomena will appear on the surface of the asphalt pavement, and the servi...
