Evaluation of different predictive dynamic modulus models of asphalt mixtures used in Argentina

The dynamic modulus of asphalt mixtures is one of the most important inputs for mechanistic empirical pavement design procedures. Several researchers have proposed different procedures for the estimation of the dynamic modulus from the volumetric mix properties, binder characteristics and aggregate gradation. This paper presents a comparison between measured and estimated dynamic modulus values using three different predictive procedures. The obtained results show that reliable first order dynamic modulus estimates for asphalt mixtures typically used in Argentina can be obtained using any of the predictive procedures considered in this study.
