    Abstract

    Knowledge of the resilient modulus (MR) of the sub-grade soils and materials that compose the layers of road pavements is mandatory for an efficient analysis of their structural behavior as a whole. However, laboratory determination of MR requires employment of relatively sophisticated loading systems and data acquisition, besides demanding considerable testing time. Therefore, it is desirable to look for standard test methods that can be used to estimate this engineering parameter. This paper presents geotechnical engineering parameters of two soils and their soil-cement mixtures, and provides empirical correlations between CBR, unconfined compression strength determined at 1% of axial strain, Young's tangent modulus, and measured values of MR of these soils and mixtures.

    Keywords:
