摘要
研究了地聚合物注浆材料在道路养护工程中的应用,并采用弯沉测试、钻孔取芯法和复注法对注浆效果进行了评估。结果表明:采用地聚合物注浆材料注浆加固道路基层与路基,治理因路基和基层强度不足、水稳定性不好导致的各种路面病害,能显著改善路基的水稳定性,提高道路承载力、改善道路弯沉值。
The application of geopolymer grouting technique in road maintenance project is researched in this paper.And deflection testing,borehole sampling and second grouting methods are used to evaluate grouting effectiveness.The results indicate that the way of geopolymer grouting technique can reinforce road base and subgrade,to treat different pavement damages due to insufficient intensity of road base and subgrade and poor water stability,with improving the water stability,road bearing capacity and road deflection value.
