水泥稳定碎石混合料强度发展规律研究

Research on strength development of cement-treated crush stone mixture in laboratory

对不同级配、水泥剂量为2．5％-5％的水泥稳定碎石混合料进行室内强度试验，分析水泥剂量、级配及养生时间对强度的影响，得到强度发展规律，对试验数据进行回归分析，建立了抗压强度与劈裂强度两者之间的相关方程。

Strength tests in laboratory carry out under different gradation and cement dosage change from 2.5 % to 5 %. Influences of cement dosage, gradation and curing time to strength are analysed, then regulations of strength development are gained. Base on the test data, rela- tionship between unconfined compressive strength and indirect compressive strength is established.
