石灰改性膨胀土路用质量控制

Quality Control for Lime- treated Expansive Soils as a Filling of Highway Embankment

根据蚌明高速公路工程实例,就弱膨胀土石灰改良后路用质量控制指标进行室内试验研究,发现将“半干半湿”的试验方法应用于实际工程的质量控制,相对来说更加合理有效。

Based on the case history of Beng-Ming expressway, the key characteristics for quality control of lime-treated expansive soils utilized as a filling of highway embankment was investigated by tests in laboratory. As the result shown, the application of intermediate path test in quality control of practical engineering, is more reasonable and effective.
