通过一系列实验分析证明 ,PA - 1型抗剥落剂加入沥青中 ,提高了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 ,从而提高了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 ,并应用于许多工程。
Through a series of experimental analysis, it is proved that PA - 1 anti - stripping agent is added to asphalt to improve the adhesion between asphalt and hard acid aggregates and make the mixture obtain larger internal friction angle and form good strength, Thus improving the high and low temperature stability of asphalt mixture, water stability, anti-fatigue properties and anti-aging properties, and applied to many projects.
