摘　　要：针对公路水泥混凝土路面出现的病害,一般会采用注浆技术进行治理。浅层填充注浆技术跟传统的"换板法"相比,优点在于不仅能利用到原路面板,减少对环境的影响,而且还可以降低公路改造工程的投入成本,经济效益高。论文结合某公路改造施工项目,针对公路混凝土板块脱空、唧泥等路面病害,采用注浆技术进行治理,并详细阐述了注浆脱空板的确定、注浆材料、设备、注浆操作以及施工要点等内容。in view of the disease of highway cement concrete pavement, grouting technologyis generally used to control. Compared with the traditional ＂plate - changing method ＂, the advantage of shallow filling grouting technology is not only to use the original road panel, reduce the impact on the environment, but also reduce the investment cost of highway reconstruction project, and the economic benefit is high. Combining with the highway reconstruction project, aiming at the pavement diseases such as take offand the word ＂ji＂ of highway concrete slab, the grouting technology is used to treat, and the determination of grouting take off board, grouting material, equipment, grouting operation and construction points are described in detail.
