Abstract

The invention discloses a fine surface treatment method for a sand-contained type bituminous pavement and belongs to the related field of bituminous road maintenance and repair. The fine surface treatment method comprises the steps that after all components of epoxy bituminous binding materials are stirred evenly as required, fine sand of a certain proportion is added, and the mixture is stirred evenly; and while continuously stirred, the mixture is evenly sprayed to the bituminous pavement with certain pressure to form a waterproof antiskid protective layer. According to the fine surface treatment method, the old bituminous pavement can be repaired fast, the antiskid capacity of the pavement and the road appearance are improved.

Description

technical field [0001] The invention relates to the related fields of asphalt pavement maintenance and repair, in particular to a fine surface treatment method for sand-containing asphalt pavement. Background technique [0002] As a seamless continuous pavement, asphalt pavement is widely used in high-grade highway construction because of its smooth surface, comfortable driving, wear resistance, low noise, short construction period, and convenient maintenance. [0003] Due to various reasons such as the complexity and variability of asphalt pavement engineering itself, structural design and construction quality control, coupled with factors such as increasing traffic volume, channelization of vehicles, aggravation of overloaded transportation and water damage, asphalt Early damage such as cracks, ruts, loose surfaces, potholes, etc. appear on the road surface (or bridge deck pavement layer) in varying degrees, which seriously reduces the performance of the road surface (or b...
