| 摘 要： | 对高速公路沥青路面早期破损主要表现形式的不同进行了分析,提出了沥青路面预防性养护单项指标方法.该指标以路面强度作为前提检验指标,以路面行驶质量指数、路面状况指数（单独列出车辙深度和裂缝率）和横向力系数作为单项指标的评价,并给出了一定的触发区间.当某一单项指标触低时,则采取相应的养护措施;当其均在触发区间时,则采取其它的综合性评价体系来确定养护时机和方式.该指标能较准确的为路面预防性养护提出警示.

| Abstract: | Based on the difference main form of the asphalt pavement early damaged,single indexes evaluation system is put forward to analyze the preventive maintenance of asphalt pavement.The pavement strength as the premise of this system,preventive maintenance indicators such as riding quality index,sideway force coefficient,pavement condition index,especially rutting depth and cracking ratio are proposed to the intervals.We should take maintaining measure,when the individual index to the limit.When all values are in the range,we should take a comprehensive evaluation system to judge the time and method of the preventive maintenance.This system can more accurately warning for Pavement Preventive Maintenance. |
