Abstract

The present invention provides a modified carbon fiber reinforced asphalt pavement anti-skid material and a preparation method thereof. The modified carbon fiber reinforced asphalt pavement anti-skid material includes the following raw materials: surface modified carbon fiber, SBS modified asphalt epoxy binder, Ultrafine organic montmorillonite, non-slip-resistant aggregate and anti-slip aggregate; wherein, the SBS modified asphalt epoxy binder includes SBS modified asphalt, epoxy resin and curing agent. The modified carbon fiber reinforced asphalt pavement anti-skid material has good wear resistance and anti-skid performance, and can effectively solve technical problems such as fast decay of asphalt pavement anti-skid performance and poor durability of the surface layer. The preparation method is simple, and the surface modification is adopted. Carbon fiber can promote the bonding of functional groups between the carbon fiber surface and asphalt and epoxy resin components, strengthen the interface performance between carbon fiber and asphalt-based materials, and improve the wear resistance and durability of the anti-skid surface layer of asphalt pavement.

Description

technical field [0001] The invention relates to the technical field of highway engineering asphalt pavement, in particular to a modified carbon fiber reinforced asphalt pavement antiskid material and a preparation method thereof. Background technique [0002] With the rapid and stable development of our country's economy, the sharp increase of traffic flow and the increasing speed of vehicles have brought obvious economic benefits, but at the same time, they have also led to continuous occurrence of traffic accidents, resulting in serious economic property losses and personal casualties. Road safety is closely related to factors such as road anti-skid performance, vehicle speed, tire type, environment, and driving behavior. Among them, the anti-skid performance of the road surface is reduced, and the adhesion of the tire is reduced. If the vehicle encounters an unexpected situation and adopts emergency braking at this time, the braking distance will be greater than the safe ...
