使用表面改性剂对沥青混合料中的矿料(包括集料和矿粉)进行表面改性,可改变矿料的表面属性,使矿料表面有机化。经表面改性后的矿料能达到“疏水、亲油”的目的,使矿料与沥青间由粘附变为键桥连接,提高沥青与矿料间的粘附性,增强抗水损害性能,改善混合料的使用品质,减少沥青路面的病害,延长使用寿命,合理使用自然资源,提高工程建设投资的经济和社会效益。
The use of surface modifiers on the asphalt mixture in the mineral (including aggregates and slag) surface modification, can change the surface properties of mineral, mineral surface mineralization. After the surface modification of mineral can achieve “hydrophobic, lipophilic ” purpose, the mineral material and asphalt by the bond into a key bridge to improve the adhesion between asphalt and mineral materials, and enhance resistance to water Damage performance, improve the quality of the mixture, reduce the disease of asphalt pavement, extend the service life, make rational use of natural resources and improve the economic and social benefits of construction investment.
