In order to investigate the factors which affect the cement improved high liquid limit clay dynamic resilient modulus and their variation laws

a series of dynamic resilient modulus tests were carried out by conducting dynamic-triaxial tests. The study demonstrated that dynamic resilient modulus values rise with the increase of confining stress

compaction degree and cement content

decrease with the increase of circular deviator stress and moisture content. To accomplish the purpose of analysis the relationships between deviator stress

bulk stress and dynamic resilient modulus

the dual-factor analysis of variance was utilized. The analysis demonstrated that both the deviator stress and bulk stress have significant effects on the dynamic resilient modulus. However

the deviator stress has more significant effects. Considering that dynamic resilient modulus is a function of deviator stress and bulk stress

with a brief analysis of adaptability of the present dynamic resilient modulus constitutive models

the three-parameters compound constitutive model which reflects the effect of bulk stress and deviator stress was utilized for experimental data regression analysis. A high coefficient of determination shows that the model which reflects the effect of bulk stress and deviator stress is accurate and credible. The prediction models used for different compaction degrees

moisture contents and cement contents were achieved; and they can provide parameters for the pavement design based on dynamic method.
