Seismic Modulus Maturity Function for Lime and Lime–Cement Stabilized Clay
AbstractStabilization via lime and/or cement is commonly used to improve poor subgrade soil. The key design parameters for lime stabilized soils and lime–cement stabilized soils (LSS/L-CSS) are strength and stiffness, the growth of which are dependent on both time and temperature. It is generally understood that increased curing temperature will result in increased LSS/L-CSS strength/stiffness; however, there is no quantitative framework for predicting this behavior. This paper proposes a modulus maturity function for LSS/L-CSS that estimates low-strain modulus as a function of the curing duration and the average curing temperature over that duration. To develop the maturity function, nondestructive seismic modulus tests were performed on cylinders cured at varying temperature regimes from three LSS/L-CSS construction sites. Variations in curing behavior were compared within and across sites and least-squares regression analysis was performed to assess the functional behavior of the data. Results indicate that seismic modulus growth in LSS/L-CSS is nonlinear in both time and temperature and should be characterized via a maturity function.
