摘要
SMA-9.5薄层罩面能够有效改善路面行驶质量、车辙性能及抗滑性能,延长路面使用寿命,以江苏省苏南某高速公路路面改造工程为依托,进行了薄层罩面混合料SMA-9.5配合比设计及性能验证,分析了薄层罩面前老路面病害处理方案及处治标准,同时结合现场施工总结了SMA-9.5混合料施工要点,可为类似工程提供参考。
SMA-9.5 overlay can improve the riding quality,anti-rutting performance and anti-sliding performance,extend pavement service life.In this paper,relying on the pavement rebulid project of one expresswayin southern Jiangsu,the mix design and performance verification of thin overlay mixture SMA-9.5 are researched,the old pavement disease treatment method and standard are analyzed.Combined with construction experience,the key points of SMA-9.5 construction are summarized to provide reference for similar engineerings.
