压浆技术在水泥混凝土路面维修养护中的应用

Application of Grouting Technique in Cement Concrete Pavement Maintenance

在路面板块尚未发生严重裂缝时,压浆是一种比较经济的修复办法。但如果初始弯沉很小并在原路面结构层的设计范围内,最好不要压浆,因为压浆所造成的扰动可能会对板块的稳定性产生影响。压浆不能提高结构的设计承载能力,也不能完全消除板块的垂直沉降,但由于空隙被填充,能明显地减小路面弯沉,恢复路面结构的整体性。

When no serious crack occurs in road plates, grouting technique is economic for maintenance. But if initial deflection is small and in the designed range of the pavement structures, it＇d better not grout or the plate stability will be impacted by disturbance caused by grouting. In addition, grouting not only can not improve the designed carrying capacity, but also can not make the vertical settlement distinguish. However, grouting technique can minish evidently the pavement deflection and renew the integrity of pavement structure.
