Abstract

The invention relates to a thermosetting epoxy-asphalt pavement material and a preparation method thereof. The thermosetting epoxy-asphalt pavement material comprises the following components in parts by weight: 13-16 parts of petroleum asphalt, 8-13 parts of polybutadiene resin, 11-14 parts of bisphenol F-type epoxy resin, 5-7 parts of polyazelaic polyanhydride, 2-3 parts of glutaric anhydride, 6-9 parts of palmitic acid and 3-5 parts of sodium hexametaphosphate. The preparation method of the thermosetting epoxy-asphalt pavement material comprises the steps of: high-temperature dissolving, mixing, stirring, reaction and thermal insulation. The prepared epoxy-asphalt pavement material has good thermosetting property and high hardness.

Description

Technical field [0001] The present invention involves a pavement material and its preparation methods, especially a thermosetomic epoxy asphalt pavement material and its preparation methods. Background technique [0002] Path materials are usually laid on the road, and road materials plays a lot of functions on the road, such as waterproof, abrasion, flame retardant, high temperature resistance, etc.These properties have higher requirements for road materials. If you cannot meet the above performance well, it will affect the traffic safety of the road. [0003] The heat resistance of conventional pavement materials is poor, and it will be softened and melted at high temperature in a high temperature state for a long time.Along with the vehicle's driving, there is still a certain loss on the road materials.These will greatly affect the smoothness of the road and improve the thermal performance and hardness of pavement materials, especially the thermal performance and hardness of e...
