Resilient Moduli Behavior of Lime-Cement Treated Subgrade Soils
This paper presents the behavior of resilient moduli properties of three subgrade soils selected from north Texas. These soils were tested for resilient modulus in accordance with AASHTO T-307 method. Lime-cement stabilization was first attempted on the control soils, the treated soils were also subjected to the same tests to evaluate the effectiveness of treatments in enhancing their resilient characteristics. Resilient Moduli values of untreated soils varied from 30 to 50 MPa whereas the same for treated soils varied from 90 to 150 MPa. Results showed a significant increase in the resilient properties of soils with lime-cement stabilization method. Also, the Universal model was used to analyze the effects of confining and deviatoric stresses on both soils. Model parameters for both lime-cement treated and untreated soils are determined and tabulated. Influence of chemical treatments on the model constants are explained.
