破碎压实技术在旧水泥混凝土路面改建中的应用

The application of fragmentation and compaction technique to the rebuilding of the old cement concret pavement

旧水泥混凝土路面加铺改造沥青混凝土路面是旧水泥路修复改造的一种重要方法,但沥青加铺层反射裂缝问题一直没有解决,严重影响了沥青加铺层的使用寿命;水泥混凝土路面破碎压实技术是修复严重损坏水泥路面的一项新技术,具有工程造价较低,施工方便,对交通影响小的优点,同时能有效地防止反射裂缝的发生,为新建路面提供良好的行车性能。

The rebuilding by adding an asphalt concret pavement is an important technique to rebuild the old cement concret pavement,but the question on the reflection crack of the added asphalt layer is to be solved and it badly influences the using life of the added layer.The flagmentation an compaction technique is a new technique to repair the baddly damaged cement concret pavement,with low project costs,simple construction and little influence to traffic,at the same time,it can prevent the reflection crack effectively and supplies good travelling performance.
