| 1、沥青改性 1. Asphalt modification 高粘沥青改性剂能大幅提高沥青的粘度，将它与基质沥青按一定配比混合，经过特殊工艺制成高粘沥青，在60℃时粘度不小于20000 Pa.s，从而有效提高沥青混合料的各种路面性能。 High viscosity asphalt modifier can greatly increase the viscosity of asphalt, mix it with base asphalt according to a certain proportion, and make high viscosity asphalt by special process. The viscosity is not less than 2000 Pa.s at 60 C, thus effectively improve the performance of asphalt mixture. 2、提高稳定性 2, improve stability 高粘沥青改性剂在拌和的过程中受高温的作用软化后，与沥青和集料充分结合并填充嵌挤到级配骨架的空隙中，限制了矿料颗粒间的相对滑动，加强了混合料之间的相互作用力，使混合料结构更稳定。 High viscosity asphalt modifier is softened by high temperature in the mixing process. It combines with asphalt and aggregate fully and fills and squeezes into the void of graded skeleton, which limits the relative sliding of aggregate particles, strengthens the interaction between the mixture and makes the structure of mixture more stable. 3、变形恢复 3, deformation recovery 高粘沥青改性剂在高温时投入沥青混合料的拌和设备中，添加剂处于粘流态，通过润湿和浸润作用，改性剂均匀地包裹在矿料颗粒表面。当温度冷却后，处于弹性状态的矿料胶结的界面具有很高的刚度和强度。 When high viscosity asphalt modifier is put into the mixing equipment of asphalt mixture at high temperature, the additive is in viscous flow state. Through wetting and infiltration, the modifier is evenly wrapped on the surface of aggregate particles. When the temperature is cooled, the interface of the mineral material cemented at the elastic state has very high stiffness and strength. 4、增加强度 4, increase strength 高粘沥青改性剂中的聚合物形成的微结晶区具有相当的劲度，它在拌合过程中拉丝成纤维状，纤维体之间相互搭接，缠绕在一起，形成一个体网状结构，将矿料颗粒牢固地限制在网络内，从而使沥青混合料整体强度得到更大的提高。 The micro-crystalline zone formed by the polymer in the high-viscosity asphalt modifier has considerable stiffness. During the mixing process, the polymer wires become fibrous, the fibers overlap and intertwine with each other, forming a single network structure, and the aggregate particles are firmly confined to the network, so that the overall strength of the asphalt mixture is greater.
