为探究Zycosoil抗剥落剂的使用效果,利用表面自由能和动态模量的关系模型,求得沥青剥落过程中集料裸露于水的面积百分比P,并以此作为沥青混合料水稳定性的评价指标,通过比较添加Zycosoil前后的沥青混合料P值的变化,分析Zycosoil抗剥落剂对沥青混合料水稳定性的影响。结果表明:P值可有效表征沥青混合料的水稳定性;添加Zycosoil抗剥落剂后,沥青混合料的抗水损害能力显著提高。
In order to explore the effect of Zycosoil anti-stripping agent, the relationship between surface free energy and dynamic modulus was used to determine the area percentage (% P) of aggregate exposed to water during asphalt spalling, which was used as an evaluation of water stability of asphalt mixture The influence of Zycosoil anti-stripping agent on water stability of asphalt mixture was analyzed by comparing the P value of asphalt mixture before and after the addition of Zycosoil. The results show that P value can effectively characterize the water stability of asphalt mixture. The addition of Zycosoil anti-stripping agent can significantly improve the water resistance of asphalt mixture.
