两种压浆材料在旧路处治中的应用研究

摘要

In order to study the two kinds of grouting materials in this project of old road’s dispos-al,combined with repair engineering of Leiyang to Yizhang,a section of Beijing-Hong Kong-Macao ex-pressway (G4),this paper approached a subject from different angles,such as investigation and statis-tics of pavement’s disease,mix proportion and performance tests of the grouting material,grouting dis-posal’s process and it’s quality testing methods.The results will provide a reference value for the repair and the old road’s disposal of expressway and other highways.%结合耒宜高速公路大修工程，对本项目旧路处治采用的2种压浆材料进行研究，从病害调查、压浆材料的配合比与性能试验、压浆处置工艺流程、质量检测方法等方面对2种压浆材料进行探讨，为高速公路及其它公路的维修与旧路处治提供参考价值。
