Abstract

The invention discloses a fine surface processing method for a single-layer paved bituminous pavement, belonging to the related field of maintenance and repairing of bituminous pavements. The processing method comprises the steps of uniformly mixing all components of epoxy bitumen binding materials, uniformly spraying the mixed components to the bituminous pavement according to a certain pressure, and uniformly scattering a layer of fine sand synchronously to form a waterproof anti-skidding protection layer. According to the method, the old bituminous pavement can be repaired rapidly, and the anti-skidding capability and pavement appearance can be 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 single-layer 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 brid...
