Description

technical field [0001] The invention relates to the technical field of asphalt modification processing, in particular to a new modified asphalt pretreatment process. Background technique [0002] Asphalt modifier refers to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixture, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. For example, in order to improve the mechanical properties (strength and toughness, etc.) of asphalt, materials such as polymers, resins, plastics, carbon black, and inorganic salts are added to increase the strength and toughness. The main purpose of adding modifiers to asphalt is to improve the road performance of asphalt mixture at high temperature, reduce permanent deformation at high temperature, improve its anti-rutting, anti-fatigue, anti-aging, and resist low-temperature cracking or increase low-temperature The performance of anti-fatigue ability and other aspect...
