Abstract
A Warm Mix Asphalt (WMA) and a Rubberized Asphalt Concrete (RAC) have been compared with a traditional Hot Mix Asphalt Concrete through the use of a specific software called CalME, developed for Caltrans. The required performance models’ parameters have been inferred from the laboratory characterization of those materials through the use of the Superpave Simple Shear Constant Height Test (SST) and the 4 Point Bending Fatigue Test (4PB). The difference between these two materials flatly arises from their simulated rutting and fatigue behaviours.
