| 什么是高粘沥青改性剂？ What is a high viscosity asphalt modifier? 高粘沥青改性剂是一种外观为浅黄色或淡黑色颗粒状的新型路面复合材料，与基质沥青按一定配比混合，采用特殊工艺制成的高粘沥青；能大幅提高沥青的粘度，60℃粘度不应小于20000 Pa.s，可直接进行沥青混凝土改性，无需特殊设备，省去强剪切制备改性沥青及改性沥青稳定化过程。 High viscosity asphalt modifier is a new type of pavement composite material with light yellow or light black granules, which is mixed with matrix bitumen in a certain proportion and uses special technology to improve the viscosity of asphalt. The viscosity of asphalt should not be less than 20000 Pa.s, and it can be directly connected to the asphalt concrete. Special equipment saves the stabilization process of modified asphalt and modified asphalt by strong shear. 高粘沥青改性剂加入重交通道路石油沥青中，通过一定的工艺对沥青进行改性，不但能够改善、提高沥青、沥青混合料与沥青路面的高温稳定性，低温变形性以及抗疲劳性能，而且还能对混合料的水稳定性和低温抗开裂性能有所改善 With high viscosity asphalt modifier added to heavy traffic road petroleum asphalt, the modified asphalt can not only improve and improve the high temperature stability, low temperature deformability and fatigue resistance of bitumen, asphalt mixture and asphalt pavement, but also the water stability and low temperature cracking resistance of the mixture.
