摘要
针对辽宁省高速公路沥青路面出现的坑槽病害,阐述了基于高掺量回收沥青路面材料(RAP)的耐久可流动沥青路面坑槽修补技术的材料组成、配合比设计和施工工艺。通过现场试验段观测及性能监测,分析该技术应用于辽宁省高速公路路面养护的实际效果。结果表明,该技术可提升坑槽修补质量,延长路面使用寿命,具有可行性和高效性。
In response to the asphalt pavement pit defects of expressways in Liaoning province,the material composition,mix design and construction technology of the durable and flowable asphalt pavement pit repair technology based on the high content recycled asphalt pavement material(RAP)are elaborated.The actual effects of applying this technology in the expressway pavement maintenance in Liaoning province are analyzed through on-site experimental section observation and performance monitoring.The results show that,this technology can improve the quality of pit repair,and prolong the service life of road surface,and it is feasible and efficient.
