The RAP (Reclaimed Asphalt Pavement) utilization in bituminous mixtures highlights the need to evaluate the effects RAP binder produces in terms of stiffness and brittleness increase. The research is focused on the evaluation of the mechanical properties of a bituminous mixture containing a significant percentage of RAP and produced with a controlled viscosity bitumen. Both the fresh and the RAP binder have been characterized at low temperatures by the BBR. The research has pointed out a general increase in stiffness induced by the RAP binder, but the mixture maintains a good workability even if the fatigue resistance is lightly reduced.

Abstract

The RAP (Reclaimed Asphalt Pavement) utilization in bituminous mixtures highlights the need to evaluate the effects RAP binder produces in terms of stiffness and brittleness increase. The research is focused on the evaluation of the mechanical properties of a bituminous mixture containing a significant percentage of RAP and produced with a controlled viscosity bitumen. Both the fresh and the RAP binder have been characterized at low temperatures by the BBR. The research has pointed out a general increase in stiffness induced by the RAP binder, but the mixture maintains a good workability even if the fatigue resistance is lightly reduced.
