Performance characteristics of high reclaimed asphalt ...

This paper investigates the performance characteristics and workability of high reclaimed asphalt pavement (RAP) mixtures in the presence of a bio-modified binder. Accordingly mixtures with high percentages of RAP were designed with and without bio-modification to examine whether bio-modification can facilitate the incorporation of RAP.
