中文摘要：

选取基质沥青和SBS改性沥青以及NaCl、CaCl_2融雪剂,制备了沥青试样,采用软化点、针入度、延度、粘度和红外光谱等试验方法,分析了氯盐融雪剂浸泡后的沥青高温性能、低温性能、感温性能、抗老化性能及红外光谱,揭示了氯盐融雪剂对沥青结合料路用性能的影响及其作用机理。分析结果表明：融雪剂提高了基质沥青的高温性能,降低了SBS改性沥青的高温性能;融雪剂降低了基质沥青的感温性能,增强了SBS改性沥青的感温性能;融雪剂降低了沥青的低温性能,但提高了沥青的抗老化性能;CaCl_2融雪剂对基质沥青路用性能的影响更明显,NaCl融雪剂对SBS改性沥青路用性能的影响更明显;融雪剂与沥青没有发生化学反应,融雪剂浸泡不会引起沥青分子结构或官能团的变化。

英文摘要：

The asphalt specimens were made by using base asphalt,SBS modified asphalt,NaCl and CaCl_2 snow-melting agents.The high temperature property,low temperature property,temperature sensitivity,anti-aging property and infrared spectrum of asphalt soaked by chlorine salt snow-melting agent were studied based on the test methods of softening point,penetration,ductility,viscosity and infrared spectrum.The influence of chlorine salt snow-melting agent on asphalt binder road performance and the erosion mechanism were revealed.Analysis result shows that chlorine salt snow-melting agent improves the high temperature property of base asphalt and reduces the high temperature property of SBS modified asphalt;it lowers the temperature sensitivity of base asphalt and enhances the temperature sensitivity of SBS modified asphalt;it reduces the low temperature property of asphalt,but improves the anti-aging property.CaCl_2snow-melting agent has more significant impact on the road performance of base asphalt,and NaCl snow-melting agent has more significant impact on the road performance of SBS modified asphalt.The snow-melting agent does not react with asphalt,and the molecular structure or functional group of asphalt soaked by snow-melting agent is not changed.8 tabs,7 figs,20 refs.
