摘要
沥再生能够有效还原老化沥青的各项性能指标，对裂缝引起的路面渗水起到很好的修复作用。室内试验评价LBP-2沥再生养护剂对老化沥青性能的还原效果，结果表明，当LBP-2掺量达到4％～6％时，还原后的沥青指标恢复到老化前水平。对LBP-2进行工程应用并检测路面指标，结果表明LBP-2对路面平整度、构造深度无影响，摆值略微减小，渗水系数明显减少。
Regenerant can effectively recover the various performance indicators of aging asphalt,and has good repair effect on surface water seepage caused by cracks.The indoor results of LBP-2 influencing the performance of aging asphalt show that the asphalt indicators come back to the level before aging when the dosage of LBP-2 reaches 4%~6%.Testing pavement indicators after engineering application of LBP-2,the results show that LBP-2 has no effect on roughness or texture depth,slight reduce on BPN,but a significant decrease on water permeability coefficient.
