采用自主技术研制了新型温拌温铺添加剂,采用简单混合的方法添加在沥青中,制得了温拌沥青,研究了添加剂对温拌沥青性能的影响。采用AC-16型SBS改性沥青混合料研究了温拌沥青的拌和温度和路用性能,确认了温拌沥青混合料在155℃的拌和温度下和热拌混合料在175℃的拌和温度下的各项性能指标基本一致。试验证明,温拌沥青混合料在此温度下的水稳性、高温稳定性和渗水性等性能均满足规范要求。
A new type of warm mix temperature shop additive was developed by independent technology. The warm mix asphalt was prepared by simple mixing method and the effect of additives on the performance of warm mix asphalt was studied. The mixing temperature and road performance of warm-mix asphalt were studied by using AC-16 SBS modified asphalt mixture. It was confirmed that the temperature of the warm mix asphalt at the mixing temperature of 155 ℃ and the mixing temperature of the hot mix at 175 ℃ The performance indicators are basically the same. The test proves that the properties of warm mix asphalt mixture at this temperature, such as water stability, high temperature stability and water seepage, all meet the specifications.
