| 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。 It is a new kind of pavement composite material with light yellow or light black granular appearance, which is mixed with base asphalt according to a certain proportion and made of high-viscous asphalt by gelidun.89ix.comgangguanp.89ix.comtongshizi.71ix.comzhuzaojm.37ix.com.cnspecial technology. It can greatly improve the viscosity of asphalt, and the viscosity at 60 ~C should not be less than 2000 Pa.s. It geshanb.89ix.comtaiyangn.89ix.comcan directly modify asphalt concrete without special equipment, and it can save the strong shear to prepare modified asphalt and stabilize modified asphalt. Cheng. 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。 High-viscous asphalt modifier is added to heavy traffic road asphalt, and the asphalt is modified by a certain process. It can not only improve the high-temperature stability, low-temperature deformation and fatigue resistance of asphalt, asphalt mixture and asphalt pavement, but also improve the water stability and low-temperature cracking resistance of asphalt mixture. |
