Journal of Civil Engineering Research 2012, 2(1): 34-40 DOI: Evaluation of Modulus of Elasticity and Modulus of Subgrade Reaction of Soils Using CBR Test Elsa Eka Putri*, N. Kameswara Rao, M. A. Mannan Civil Engineering, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, 88999, Malaysia Abstract This paper presents the procedure of evaluation of the modulus of elasticity (E) and the modulus of subgrade reaction (ks) value based on the California Bearing Ratio (CBR) tests and FEM analysis. The pressure-displacement re-sponse of the soil in the CBR mould is simulated using Cosmosworks FEM model where the soil, the load plunger, and the steel mould of CBR are represented. The correlation of Modulus of Elasticity (E) with California Bearing Ratio (CBR) is developed based on the elastic properties of the soil sample. Furthermore, the correlation between E and CBR is proposed.
2. Literature Review The modulus of subgrade reaction, s (also referred to as k Coefficient of Elastic Uniform Compression, C u) is a rela-tionship between soil pressure and deflection which is pro-
