New predictive models for the dynamic modulus of hot

2015-2-1  The specific characterization of asphalt concrete and its material properties, such as the dynamic modulus, is based on the dependence of its behavior on both the time of loading and temperature, which can be merged into a single smooth sigmoidal function. The following sigmoidal function, Eq. (3), is considered for this purpose.

Effect of Oxidative Aging on Dynamic Modulus of Hot-Mix

The dynamic modulus ( E * ) of asphalt mixtures is an important parameter in pavement design and analysis.Although the E * values of freshly prepared hot-mix asphalt (HMA) mixtures can be conveniently determined through laboratory tests, the E * values of field pavements continuously evolve as asphalt binder ages, and hence are difficult to determine.
