摘　　要：由于道路路面受到内部材料、结构及外部交通环境等因素影响,使用性能会随着服务年限增长而下降。而当紧急修补坑洞完,修补效果有限,往往数天后即可能再次发生坑洞,不论是密级配沥青混凝土的本身内部或外在环境因素都可能是坑洞产生的原因。因此,结合某国道段路面坑洞为例,提出以改性沥青取代传统沥青、水泥取代石粉措施防制剂、多孔隙沥青混凝土和炉渣多孔隙沥青混凝土的坑洞修复材料提升策略,并针对施工管养提出大胆创新的措施。结果表明,本次路面坑洞修复施工质量效果明显,可以有效降低坑洞发生的频率。Due to the influence of internal materials,structure and external traffic environment,the service performance of road pavement will decline with the increase of service life.When the emergency repair of the pit is completed,the repair effect is limited,and the pit may occur again after a few days.Whether the internal or external environmental factors of dense graded asphalt concrete itself may be the cause of the pit.Therefore,taking the pavement potholes of a national highway section as an example,this paper puts forward the promotion strategy of pothole repair materials that use modified asphalt to replace traditional asphalt,cement to replace stone powder as anti agent,porous asphalt concrete and slag porous asphalt concrete,and puts forward bold and innovative measures for construction management and maintenance.The results show that the construction quality effect of this pavement pothole repair is obvious,which can effectively reduce the frequency of potholes.
