摘　　要：沥青的再生利用对路面可持续发展具有重要意义,通过添加再生剂对SBS改性沥青进行再生研究,测试再生沥青的基本性能及流变性能,分析再生剂掺量对再生沥青的性能影响,并采用红外光谱明确再生机理。试验结果表明:再生剂的加入可以调节老化沥青中沥青质的比例,增大老化沥青的抗变形能力,再生剂未与老化沥青发生化学反应生成新物质。温度扫描表明,再生剂可使老化沥青温度敏感性降低。The recycling of asphalt can realize the sustainable development of pavement. The regeneration of SBS modified asphalt was studied by adding rejuvenating agent, and the basic properties and rheological properties of recycled asphalt were tested. Infrared spectroscopy was used to clarify the regeneration mechanism. The test results showed that the addition of the regenerant could adjust the proportion of asphaltenes in the aged asphalt and increase the anti-deformation ability of the aged asphalt. Temperature scans showed that the regenerant reduced the temperature sensitivity of the aged asphalt.
