石灰稳定皂化渣土填筑桥头引道路堤的适用性研究

为了减少路桥之间可能发生的差异沉降,防止桥头跳车,桥头引道路堤的填料应该具有轻质、高强等特性.通过试验,系统研究了石灰稳定皂化渣土混合料的强度、刚度、水稳定性等路用技术性能.试验结果表明：适当配合比的石灰稳定皂化渣土混合料密度比石灰土小25％,并且强度高、水稳定性好,满足规范的相关要求,是一种良好的桥头路堤填筑材料.

Applicability of Lime Stabilized Saponification Slag and Soil in Filling Bridge Approach Embankment

In order to reduce the differential settlement between the bridge and the approach embankment and prevent vehicle bumping at bridge-head, the material filling bridge approach embankment should have the performances of lightweight and high strength. The highway application performances of the mixture of lime stabilized saponated residue and soil, include the strength, rigidity and water stability are systematically studied by experiments. The experimental results show that the density of appropriate mixed mixture of lime stabilized saponated residue and soil is 25% lower than lime soil. The mixture has high strength and good water stability that conform to the current specification. The mixture of lime stabilized saponated residue and soil is good to be bridge approach embankment filling material.
