摘要: 选取基质沥青和SBS改性沥青以及NaCl、CaCl2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; CaCl2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。Abstract: The asphalt specimens were made by using base asphalt, SBS modified asphalt, NaCl and CaCl2 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.CaCl2 snow-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.
