ABSTRACT
This research presents the thermomechanical performances of Hot Mix Asphalt (HMA) containing conventional and regenerated Reclaimed Asphalt Pavement (RAP). Different mixtures containing 40 to 70% RAP are evaluated and compared to a control mix (without RAP). The material properties are determined through an extensive experimental program including workability, rutting resistance, susceptibility to water, stiffness, fatigue resistance and performances at low temperature. The results show that, compared to the control mixture, the use of RAP significantly increases the stiffness of the mixes without a significant loss of fatigue resistance; however, RAP does reduce the performance of HMA at low temperatures. The use of an additive allows the mixtures to partially recover properties such as workability, fatigue resistance and ductility at low temperatures.
