| 摘 要： | 以河北省某高速公路沥青路面为研究对象，通过长期性能观测数据，提出预防养护最佳时机的方法和养护措施选择原则。研究结果表明:将路面破损指标衰减幅度大，衰减后其值最接近路面破损指标养护标准上限时的年份，作为实施预防养护的最佳时机；根据路面路况水平、病害类型、预防养护措施实施效果的不同，将预防养护划分为轻度、中度、重度，并推荐相应适用的养护措施。

Study on Preventive Maintenance Timing and Maintenance Measures Selection of Asphalt Pavement on Expressway |
| |
| Abstract: | Taking an expressway asphalt pavement in Hebei Province as the research object, through long-term performance observation data, the preventive maintenance to determine the best time and the selection principle of maintenance measures are puts forward. The results of the research show that the attenuation range of pavement damage index is large, and the year when the attenuation value is closest to the upper limit of pavement damage index maintenance standard can be used as the best time to implement preventive maintenance. According to the road condition level, disease type and the effect of preventive maintenance measures, the preventive maintenance can be divided into mild, moderate and severe preventive maintenances, and appropriate maintenance measures are recommend. |
