Oct 01, 2012  The comparison of the 1-PM, 2-PM, and 1-AR asphalt—fabricated using the same neat base asphalt—leads to the conclusion that the AR asphalt–aggregate system evaluated has a higher susceptibility to moisture damage as compared to the systems formed with the two PM asphalts (Fig. 2, Fig. 3). However, as previously discussed, this comparison ...

Comparison of asphalt rubber-aggregate and polymer ...

Highlights Surface free energy and energy indices served to characterize asphalt–aggregate systems (AAS). Asphalt rubber (AR)- and polymer modified (PM)-asphalts produced comparable AAS. The AAS evaluated are representative of permeable friction course (PFC) mixtures. The energy indices computed can be used to improve the design of PFC mixtures.
