Abstract: 
One of the simplest continuous spectrum models used to characterize asphalt materials was proposed by Huet in 1963. The model was further expanded over the years (Huet-Sayegh, 2S2P1D) to better fit experimental data obtained over a wide range of temperatures. Huet model has expressions for both complex modulus and creep compliance, and therefore, it is possible to use, for example, asphalt binder Bending Beam Rheometer (BBR) creep compliance experimental data to predict Dynamic Shear Rheometer (DSR) complex modulus and vice versa.

This idea is investigated using BBR and DSR experimental data obtained on a set of asphalt binders at low and intermediate temperatures. It is found that Huet parameters in time domain could be used to obtain reasonable G* predictions, if additional restrictions are imposed on parameter k.
