| 摘 要： | 307国道鹿泉井陉路段由于多年受自然灾害的影响，加上近年来大型车辆和超限车辆的不断增加．使水泥路面出现了断板、碎板等现象。针对这种情形，设计单位提出了使用贫混凝土基层的方案。贫混凝土基层是专门针对特重交通条件，为抵抗大量超重栽车辆所开发的新型、增强的刚性基层类型。总结该工程的施工技术和经验，可为同类工程提供借鉴。

| Abstract: | Because of many years natural disaster and the increasing number of heavy vehicles and over-load vehicles, the cement pavement of 307 national highway Luquan Jingxing section has appeared broken board and particle board. Based on this over-load situation, design institution intends to utilize lean concrete for roadbase. Lean concrete is a new reinforced rigid roadbase which is special for heavy traffic. Construction techniques and experiences are summarized for similar engineering learning. |
