Abstract	The characterization of pavement materials in the proposed mechanistic-empirical pavement design (MEPD) guide involves application of the dynamic modulus technique for asphalt concrete and the resilient modulus for unbound materials. To circumvent the need for conducting the mechanical test in lower design levels, predictive equations and correlations established with physical properties are used to estimate the mechanistic properties needed as input to the design software. This paper examines the simplifications incorporated in the MEPD and the accuracy expected from this alternative in comparison with the MEPD guide proposed approach involving the use of an empirical predictive equation.
