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3d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.
Abstract
In order to improve the maintenance and management level of asphalt pavement diseases,a comprehensive analysis was con-ducted on the condition of asphalt pavement diseases in the Wulin to Lusu boundary section,and an innovative treatment plan was de-signed.The results showed that within 3 days after treatment,only a very small number of visible horizontal and vertical fine cracks ap-peared 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 deflec-tion value of about 0.135 mm,all meeting the basic requirements of actual engineering standards not exceeding 0.3 mm.
