【摘要】 通过一系列试验分析证明 PA-1型抗剥落剂加入沥青中 ,提高沥青与硬质酸性集料的粘附性 ,并且使其混合料获得较大的内摩擦角 ,形成良好的强度 ,从而提高沥青混合料的高低温稳定性、水稳定性、抗疲劳性能和抗老化性能等 ,并在许多工程上应用。通过与近几年工程使用的主要改性剂 SBS、SBR和 PE进行比较 ,说明 PA-1型沥青抗剥落剂具有最佳的经济效益比。更多还原

【Abstract】 Based on a series of tests, it is proved that PA-1 anti-stripping agent can improve the performance of the asphalt mixture including the high and low temperature stability, water stability, fatigue and aging resistance ability by increasing its cohesiveness and making it obtain an larger inner friction angle. Compared with several modifiers such as SBS, SBR and EVA, the PA-1 anti-stripping agent is the best one for the engineering applications.更多还原
