自补偿式水泥路面板底脱空处治技术

针对目前脱空处治技术和压浆材料在实际应用中的不足,为了提高脱空处治的效果,在系统分析国内部分道路浆体材料配合比的基础上,引入补偿收缩原理改良了水泥类和有机类压浆材料,针对轻度、中度、重度脱空路面提出了合适的自补偿式压浆材料,并推荐了配合比,给出了基于灌浆饱和度和弯沉的压浆效果评价标准,并通过试验路验证了压浆效果。结果表明:推荐的压浆材料处治效果良好,为压浆后的水泥路面或沥青加铺层提供了良好的承载能力,从而有效提高和延长了路面使用性能和寿命。

Self-compensation treatment technology for voids beneath cement concrete pavement

Aiming at the lack of treatment technology and mud-jack materials for voids in practical engineering,in order to improve the treatment effect for voids beneath cement slab,on the basis of systematically analysis of mix proportion of materials used in roads in China,the cement and organic mud-jack materials were improved using the shrinkage-compensating principle. Aiming at different levels of voids beneath cement pavement,the self-compensation mud-jack materials is put forward, the correct mix proportion is...
