A method of rapid estimation of the modulus of elasticity of cement stabilized materials from data that are usually available, without the need to resort to laboratory modulus determinations, is desirable especially for use in pavement analysis. This paper describes the derivation of a method for continuously graded materials, which is based on a single number grading index, that is, the gradation modulus, which can readily be calculated from the grading curve of the material to be stabilized. Another method derived empirically and based on the bulk density and optimum moisture content of the stabilized material is also presented. Predicting accuracy of the methods is compared with data available from the literature and is judged satisfactory for pavement analysis purposes.
