为掌握温拌阻燃沥青混合料实际使用效果,首先使用极限氧指数和黏度等试验分析了温拌剂和阻燃剂对沥青温拌、阻燃及常规性能的影响;然后使用锥形量热仪等研究了温拌阻燃沥青混合料的阻燃及路用性能,并采用小型加速加载试验对温拌阻燃沥青路面结构的使用耐久性进行了验证.研究结果表明:Sasobit对SBS改性沥青有明显的温拌效果,FRMAXTM有明显的阻燃效果,且两者互不影响;Sasobit能改善SBS改性沥青高温性能,降低其低温性能,FRMAXTM对温拌沥青高温性能和低温性能都有不利影响,同时两者对存储稳定性无影响;FRMAXTM能明显提升SBS改性沥青混合料的阻燃抑烟性能,Sasobit对阻燃沥青混合料阻燃性能不利,但能改善其抑烟性能;Sasobit和FRMAXTM对SBS改性沥青混合料高温稳定性无影响,略微降低其低温抗裂性和水稳定性,抗疲劳性能明显降低;温拌阻燃沥青混合料路面结构有良好的抗车辙和抗滑耐久性.“,”In order to grasp practical application effect of warm-mixed flame retardant asphalt mixture,the influences of warm-mixed agent and flame retardant agent on warm mix,flame retardant and regular performance were firstly analyzed based on limiting oxygen index and viscosity test and then the technical performance of warm-mixed flame retardant asphalt mixture was investigated by cone calorimeter.The durability of warm mixed flame retardant asphalt pavement was verified by the accelerated loading test.The results show that there exist obvious warm-mixed effect of Sasobit on SBS modified asphalt and obvious flame retardant effect on FRMAXTM,without any interference.Based on Sasobit,high temperature performance of SBS modified asphalt is improved and low temperature performance drops.However,FRMAXTM has a negative effect on both high temperature and low temperature performance of warm-mixed asphalt,without storage stability being influenced.Flame retardant and smoke suppression performances of SBS modified asphalt can be significantly improved by FRMAXTM,and Sasobit is detrimental to the flame retardant performance of flame retardant asphalt mixture,but with improvement of the smoke suppression performance.With no influence of Sasobit and FRMAXTM on high temperature stability of SBS modified asphalt mixture,low temperature crack resistance and water stability slightly decrease and anti-fatigue performance declines.Warm-mixed flame retardant asphalt pavement structure shows a good durability on rutting resistance and anti-slide performance.
