首先研究了3种不同阻燃剂对 SBS 改性沥青阻燃性和物理技术指标的影响，进而研究了不同复合阻燃剂改性方案下阻燃沥青混合料路用性能差异。试验结果表明，阻燃剂的加入可有效提高 SBS 改性沥青的极限氧指数，但也会对 SBS 改性沥青的低温抗裂性和水稳定性产生不利影响，相比经复合改性后的阻燃沥青混合料其综合路用性能均有较大提升，其各项路用性能指标均满足规范要求。

This paper studies the effects of three different flame retardants on SBS modified bitu-men and physical specifications,and then studied under different programs composite flame retardant modified asphalt pavement performance differences.The results showed that adding flame retardants can effectively improve the limiting oxygen index of SBS modified asphalt,but it can also adversely affect the stability of SBS modified asphalt crack resistance and low temperature water,compared to the composite modified by the flame retardant asphalt road performance are its comprehensive greatly improved its road performance indicators to meet regulatory requirements.
