特别注意液态的抗剥落剂应保存在常温的环境
1、一般来说,抗剥落剂的酸碱度都是PH:>7。
1. Generally speaking, the acidity and alkalinity of anti-stripping agents are PH:> 7.
2、密度:应与沥青密度相当或接近(0.90~1.15g/cm3)。
2. Density: It should be equal to or close to asphalt density (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: Solidification point is less than 0 C. Special attention should be paid to the liquid anti-stripping agent which should be kept at room temperature without precipitation.
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%。
4. Pavement performance requirements: compatibility of anti-stripping agent, asphalt and stone. For granite, basalt aggregate and anti-stripping agent mixed with asphalt, after aging, the adhesion grade between asphalt and aggregate by boiling should reach grade 5, and the strength ratio of freeze-thaw splitting test should not be less than 80%.
