抗剥落剂的技术标准:
Technical standards for anti stripping agent:
1、一般来说,抗剥落剂的酸碱度都是PH:>7。
1. In general, the acidity and alkalinity of the anti peeling agent are PH: > 7.
2、密度:应与沥青密度相当或接近(0.90~1.15g/cm3)。
2, density: the density of the asphalt should be equal to or close to (0.90 ~ 1.15g/cm3).
3、凝固点:凝固点为<0℃,特别注意液态的抗剥落剂应保存在常温的环境,并且不得有沉淀物,
3, solidification point: the freezing point is less than 0 C. The anti stripping agent of the liquid should be kept in the ambient temperature, and the sediment should not be deposited.
4、路用性能要求:抗剥落剂、沥青、石料有配伍问题,对于花岗岩、玄武岩集料、抗剥落剂掺入沥青后,经老化后应使沥青与集料水煮法粘附性等级达到5级,冻融劈裂试验强度比不应小于80%。
Performance requirements: 4, anti stripping agent, asphalt, stone has compatibility problems for granite, basalt aggregate and anti stripping agent mixed with asphalt after aging, the boiling method of asphalt and aggregate adhesion level reaches 5, the freezing thawing split should not be less than 80%.
