摘要
针对高寒地区的气候和环境条件,采用正交试验方法,综合考虑矿料的骨架作用、沥青用量、矿粉用量,以劈裂强度(15℃)、冻融循环后残留强度比(-18℃和-28℃)作为评价指标,进行沥青稳定基层混合料抗冻性能研究。研究结果表明,通过调整沥青混合料内部粗、细集料的比例,采用合适的矿粉用量,选取适当的粉胶比等措施,可以使混合料的抗冻性能更优。
Based on the characteristic of base course,the orthogonal experimental study on mixture for stable asphalt base course was conducted.The results showed that: The performance of mixture can become even more excellent by adjusting the proportion of coarse granule and adopting proper dosage of mine powder and asphalt.
