摘　　要：为了提高沥青路面病害的维修管理水平,综合分析吴林至鲁苏界段沥青路面病害情况,设计处治方案,结果显示,治理后3 d内,全段沥青路面仅出现极少数可看到的横向、纵向细缝,未出现车辙、裂缝、坑槽、沉陷等情况,方案具有可行性。对于随机8组检测芯样,压实度检测结果均大于95%,最大弯沉值为0.245 mm,弯沉值的平均值约为0.135 mm,均满足实际工程标准不大于0.3 mm的基本要求。In order to improve the maintenance and management level of asphalt pavement diseases,a comprehensive analysis was conducted on the condition of asphalt pavement diseases in the Wulin to Lusu boundary section,and an innovative treatment plan was designed.The results showed that within 3 days after treatment,only a very small number of visible horizontal and vertical fine cracks appeared on the entire asphalt pavement,and there were no ruts,cracks,pits,sinking,etc.The plan is feasible.For 8 randomly tested core samples,the compaction test results were all greater than 95%,with a maximum deflection value of 0.245 mm and an average deflection value of about 0.135 mm,all meeting the basic requirements of actual engineering standards not exceeding 0.3 mm.
