Abstract:

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 coresponding pavement perform-ances 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 deter-mined 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.More-over,by the experiments in the field,the construction procedure and techniques for the ISS-strengthened soil pave-ment 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 Ihe ISS-strengthened soil pavement has the advantages of good beating capability,evenness,durability,anti-water stability,simplicity,fa-cility,low cost and obtaining raw materials on the spot.

Key words: ionic soil stabilizer, strengthened soil, embankment, dam, pavement
