摘　　要：分别选取氯化钠、氯化镁、氯化钙、CMA等融雪剂,测试其对沥青针入度指数、软化点及延度等指标的影响。结果表明,氯化镁对沥青针入度指标影响最大,CMA最小;氯化钙对沥青软化点影响最大,氯化镁最小;氯化钠对沥青延度的影响最大,CMA影响最小。由此说明,4种融雪剂对沥青的性能有一定的影响,且CMA为一种对沥青影响较小的环保型融雪剂。Sodium chloride,magnesium chloride,calcium chloride,CMA and other snowmelt agents were selected respectively to test their effects on indexes such as penetration index,softening point and ductility. The results showed that magnesium chloride had the greatest influence on the index of penetration and CMA was the smallest. Calcium chloride had the greatest influence on softening point of asphalt,while magnesium chloride had the least influence. Sodium chloride has the greatest influence on pitch ductility and CMA has the least influence. This shows that the four snowmelt agents have certain influence on the performance of asphalt,and CMA is an environment-friendly snowmelt agent with less influence on asphalt.
