废旧SBS改性沥青的再生是研究废旧SBS改性沥青混合料再生技术的基础。分别把LAC-20和SMA-16两种不同废旧SBS改性沥青混合料,采用溶剂抽提的方法抽提出旧沥青,并进行理化性质及组分分析,根据其性质和组成情况选择A#剂与B#剂作为再生剂,调配出符合公路沥青路面施工技术规范(JTG F40-2004 I-A类)聚合物改性沥青技术要求的重交通道路石油沥青。利用再生剂调和旧沥青使其再生,这正是本方法的创新之处。
The regeneration of waste SBS modified asphalt is the basis for researching the regeneration technology of waste SBS modified asphalt mixture. LAC-20 and SMA-16 two different SBS modified asphalt mixtures were extracted by solvent extraction of the old asphalt, and physical and chemical properties and composition analysis, according to their nature and composition of the choice of A # agent and B # agent as a regenerant to formulate heavy traffic asphalt pavement in line with the technical requirements of polymer modified asphalt of the technical specification for highway asphalt pavement construction (Class JTG F40-2004 IA). It is the innovation of this method to use the regenerant to reconcile the old asphalt.
