高速公路沥青路面大修养护标准及对策分析

为了保证路面大修养护方案的科学性，依托京沪高速公路沂淮江段路面大修工程，通过对原路面结构形式、路面剩余寿命的分析，了解了现阶段京沪高速公路对于大修养护的需求，同时根据路面状况数据，结合已有研究成果，采用数理统计方法进行了大修养护标准分析探讨，在此基础上，结合工程经验制定了大修养护原则，并据此进行了大修养护对策设计。分析结果表明：科学的大修养护方案制定对于提高京沪高速公路路面服务水平，延长路面使用寿命具有重要现实意义。

Research on Standard and Program of Major Repair and Maintenance for Expressway Pavement

In order to ensure the scientific nature of major repair and maintenance program,relying on pavement major repair engineering of Yihuaijiang section of Jinghu expressway,the demands of Jinghu expressway for major repair and maintenance were investigated. At the same time,according to condition data of pavement and combined with existing research results,the standard of major repair and maintenance was analyzed using mathematical statistical method. On this basis,the principle of major repair and maintenance was established in combination with engineering experience,and the program for major repair and maintenance was also designed. The results show that a scientific maintenance program has important practical significance for improving service levels of Jinghu expressway and extending the pavement life.
