利用乙二胺四乙酸 (EDTA)法可快速测定水泥或石灰稳定土中水泥或石灰剂量 ,通过室内和现场实验比较分析发现稳定土中的水泥或石灰剂量随时间衰减 ,会影响到现场测试结果 ,为此可建立EDTA消耗量和灰剂量回归公式 ,并以此对现场剂量检测和路基压实结果进行修正
Using ethylenediaminetetraacetic acid (EDTA) method can quickly measure the cement or lime stabilized soil cement or lime dosage, through laboratory and field experiments and comparative analysis found that stable soil cement or lime dose decay over time, will affect the field test results , For which a regression formula for EDTA consumption and ash dosage can be established and used to correct field dose testing and subgrade compaction results
