摘　　要：采用有机蒙脱土(OMMT)、硫(S)、炭黑(CB)三种稳定剂与SBS复合改性沥青混合料,其最佳掺量分别为6%、2%、5%,对复合改性沥青进行配合比设计,并开展沥青离析试验、三大指标试验。结果表明:OMMT能够显著地提升SBS改性沥青的动稳定度、水稳定性和抗疲劳性能,但对混合料的低温性能有消极的影响;S稳定剂在较低掺量下能提高SBS沥青混合料的高温抗车辙和低温抗开裂能力;而CB稳定剂降低了混合料的低温抗开裂和抗水损害能力。The optimum mixing ratio of three kinds of stabilizers of organic montmorillonite(OMMT),sulfur(S),carbon black(CB)with SBS is 6%,2%,5%.The mixture ratio of the modified asphalt was designed,and the asphalt segregation test was carried out,and three major indexes were tested.The results show that OMMT can significantly improve the dynamic stability,water stability and fatigue resistance of SBS modified asphalt,but has a negative effect on the low temperature performance of the mixture.S stabilizer on SBS modified asphalt is reflected that in the lower content of the mixture can improve the anti-rutting and low temperature anti-cracking effect;while CB reduce the low temperature cracking and water damage capacity of mixture.
