离子土固化剂加固堤坝道路路面的路用性能

结合广东湛江地区志满水库引水渠道离子土固化剂（ISS）加固土堤坝道路路面试验工程，开展ISS加固土堤坝道路路面的路用性能研究，通过室内试验，得出ISS加固土的压实特征、强度特征和水稳定性，提出固化材料配合比设计主要根据混合料的强度及水稳性来确定的设计原则，试验得出加固现场含砂高液限粉土的加固材料最佳配合比为每立方米土中掺加0．3L ISS和6％（与干土的质量比，下同）的石灰．通过修筑试验路，总结ISS加固土路面施工组织方法和施工工艺，对比研究厂拌法和路拌法施工工序、加固效果和经济效益．研究表明：ISS加固土路面具有较好的承载能力、平整度、耐久性和水稳定性．可就地取材．施工方便．造价低．

Pavement Performances of Dam Embankment Roads Strengthened by Ionic Soil Stabilizer

The tests of pavements of dam embankment roads strengthened by ISS(Ionic Soil Stabilizer),located in the ditch of Zhiman reservoir in Zhanjiang,Guangdong,were carried out,and the corresponding pavement performances of the roads were investigated.In laboratory,the compaction feature,intensity feature and anti-water stability of the ISS-strengthened soil were tested,thus coming to the conclusions that the mixture proportion is mainly determined by the strength and anti-water stability of the mixture and that the optimum mixture proportion in site for the sandy silt with high liquid limit is 0.3L of ISS per cube meter soil and 6% limestone of the dry soil in mass.Moreover,by the experiments in the field,the construction procedure and techniques for the ISS-strengthened soil pavement were summed up,and the construction procedure,stabilizing effect and economical benefit of the mixing in plant and the mixing in place were then compared and analyzed.The results indicate that the ISSstrengthened soil pavement has the advantages of good bearing capability,evenness,durability,anti-water stability,simplicity,facility,low cost and obtaining raw materials on the spot.
