【摘要】 为了评价掺加融雪剂的融冰化雪型沥青混合料的路用性能,通过与普通沥青混合料的对比试验,研究了含融雪剂的沥青混合料的高温稳定性、低温抗裂性、水稳定性及抗疲劳性能等。结果表明:掺加融雪剂对沥青混合料的最佳油石比没有太大的影响,在相同的级配条件下,融冰化雪型沥青混合料具有优良的高温稳定性,但其低温抗裂性能有所降低,水稳定性有少量的增加,抗疲劳性能不及普通沥青混凝土。更多还原

【Abstract】 In order to evaluate the road performance of ice-melting asphalt mixture,a series of contrast experiments with ordinary asphalt mixture have been conducted to study the high temperature stability,low temperature cracking resistance,water stability,and fatigue resistance.The results show that addition of deicing salt has no obvious influence to the optimal aggregate ratio.In the same aggregate grading,ice-melting asphalt mixture has better high temperature stability,while the low temperature cracking resistance and fatigue resistance is less than ordinary asphalt mixture,and the water stability goes on a little increase.更多还原
