Study and Application of NewRepair Material“Express Repair”for ShallowPatch of Cement Pavement

机场水泥混凝土道面在使用早期,道面主要病害以功能性损坏为主。目前机场主要采用快凝早强水泥混凝土进行修补,维修效果较差。该文对新型浅层补丁修补材料"特快补"的作用机理、技术参数和施工工艺进行了详细介绍,并分析了该材料在我国的应用状况,可供同行参考。

In the early stage of use,the main fault of cement concrete pavement in airport is the function damage.The present repair method is the quick-solidified early-strength cement concrete used for the airports now,but its repair effect is poor.The article introduces the action mechanism,technical parameters and construction technology of the new shallow patch repair material 'express repair'in detail,and analyzes its application in China,which can be referred for the similar projects.
