稳定过湿土作路基填料的试验研究
EXPERIMENTAL RESEARCH ON TAKING STABILIZED OVERWETTED SOIL AS ROADBED FILLER
【摘要】 将HAS土壤固化剂按3%、4%的比例掺入过湿土,并测试了稳定土的击实、CBR、无侧限抗压强度等力学指标。结果表明,稳定后的过湿土,其力学性能完全达到路基填料的要求,此外结合XRD分析,对HAS固化剂稳定过湿土的化学机理进行探讨。
【Abstract】 Overwetted soil is mixed with 3%,4% by HAS soil stabilizer,mechanical indexes of stabilized soil such as,the compaction,CBR and unconfined compressive strength were measured.Results show that the mechanical behaviors of stabilized overwetted soil meet completely the requirements of filling materials in road bed.Besides,the chemical mechanism of stabilized overwetted soil by HAS stabilizer was explored with the XRD analysis.
