Nominal property based predictive models for asphalt mixture complex modulus (dynamic modulus and phase angle)

Academic Article


  • Dynamic modulus (vertical bar E*vertical bar) and phase angle (8) are necessary for determining the response of asphalt mixtures to in-service traffic and thermal loadings. While a number of [El and 8 predictive models have been developed, many of them require lab measured properties (e.g. binder complex modulus). The majority of previous work has focused only on prediction of vertical bar E*vertical bar, limited models exist for prediction of delta. This research utilized generalized regression modelling of lab measurements (from 81 asphalt mixtures) to develop and verify prediction models for vertical bar E*vertical bar and 5 using only nominal asphalt mix properties that are readily available during the initial mixture design and specification process.
