以欢喜岭AH-90沥青为基质沥青,采用添加SBS改性剂的方法制得SBS改性沥青。其针入度、软化点、延度等指标符合JTJ036—98I-C标准,对其进行第一次老化,制得废旧SBS改性沥青。对废旧SBS改性沥青再加入适量的再生剂和SBR,使废旧SBS改性沥青的理化指标重新恢复到JTJ036—98I-C标准的要求,制得再生SBS改性沥青,再对其进行第二次老化。结果表明废旧SBS改性沥青可以通过再生的方法加以重新利用。
With joy Ridge AH-90 asphalt as the base asphalt, SBS modified asphalt was obtained by adding SBS modifier. Its penetration, softening point, ductility and other indicators in line with the JTJ036-98I-C standards, the first aging of its system, obtained waste SBS modified asphalt. Recycled SBS modified asphalt, and then add the right amount of regenerant and SBR, so that the physical and chemical indicators of waste SBS modified asphalt back to the requirements of JTJ036-98I-C standard, and then made of recycled SBS modified bitumen, and then its second Aging. The results show that the waste SBS modified asphalt can be recycled by way of re-use.
