摘　　要：通过试验,研究了不同浓度下两种氯盐融雪剂对集料力学性能、沥青与集料的黏附性的影响。结果表明,经过融雪剂浸泡的沥青混合料在干湿循环和冻融循环后,集料强度降低、沥青与集料的黏附性降低,融雪剂浓度对集料强度、集料与沥青的黏附性有不同的影响规律。The research on the influence of two kinds of chloride salt snow-melting agents at different concentration on the mechanical property of aggregate and adhesivity of asphalt and aggregate is made through the test. The results show that,after drying and watering cycle and freezing and thawing cycle of asphalt mixture soaked in snow-melting agent,the intensity of aggregate is reduced,the adhesivity of asphalt and aggregate is reduced,and the concentration of snow-melting agent has different influence rules on the intensity of aggregate and adhesivity of aggregate and asphalt.
