沥青还原剂在沥青路面预防性养护中的应用研究

Research on Application of Asphalt Reductant on Preventive Maintenance of Asphalt Pavement

沥青还原剂封层技术是一种常用的沥青路面预防性养护技术。阐述了还原剂养护材料的性能要求和评价方法,并就还原剂对沥青的恢复作用进行了研究。结合应用情况,对沥青还原剂预防性养护技术的施工技术做了简要的介绍,并对处理后效进行了评价。研究表明,沥青还原剂对老化的沥青路面性能具有一定的恢复作用,对路面细微裂缝有一定的封堵作用,但在一定程度上会降低路面的抗滑能力。

Sealing with asphalt reductant is a common technology of preventive maintenance of asphalt pavement.The performance requirement and evaluation methodology of reductant are described,and which recovery role on asphalt is studied here.Combined with application,it introduces the construction technology briefly,and evaluates its treatment effect.The research shows that asphalt reductant has certain effect on recovering the performance of asphalt pavement and sealing pavement subtle cracks,however it may reduce the skid resistance of pavement.
