近年来,随着高等级公路建设的飞速发展.交通量日益增大,大型重载车量的逐渐增加,普通沥青路面早期病害现象越来越严重。如高温车辙拥包、网裂、渗水和坑槽等。目前采用SBS改性沥青可显著提高沥青路面的使用性能,这也已经被业界所认识,因此SBS改性沥青近年来得到了广泛的应用。由于改性剂品牌较多,不同类型、不同品牌的改性剂对改性沥青的指标性能都有较大影响,对混合料的配合比影响也. In recent years, along with the rapid development of high-grade highway construction, traffic volume is increasing day by day, and the volume of large-scale heavy-duty vehicles gradually increases. The early disease of ordinary asphalt pavement is more and more serious. Such as high temperature rutting package, net crack, seepage and pit and so on. SBS modified asphalt currently used can significantly improve the performance of asphalt pavement, which has also been recognized by the industry, SBS modified asphalt has been widely used in recent years. As the modifier brand more, different types and brands of modifiers have a greater impact on the performance indicators of modified asphalt, the mix of mix also affect.
