“…There are abundant data indicating that properly specified and produced recycled hot mix asphalt is equivalent to conventional hot asphalt in terms of rutting, raveling, weathering and fatigue cracking (Solaimania et al, 1996;Stroup-Gardiner et al, 1999;Soleymani et al, 2000;Karsson et al, 2003;Buttlar et al, 2005;Airey et al, 2005;Chen et al, 2007;Miro et al, 2008;Daniel et al, 2008). Apparently the paving industry has started the use of R 2 AP in binder and surfaces courses.…”

Reclaimed asphalt pavements (RAP) have been called one of the most recycled materials in the world. Pavements mixed with RAP would be milled or excavated when they reach the end of service life. The reuse of RAP makes it as a second RAP, and is referred as R 2 AP in this study. R 2 AP was added at ten levels to hot-mix asphalt mixtures (HMA) with four different recycling agents in the laboratory. Adding 40% R 2 AP did not appear to alter the mixture properties dramatically. When the percentage was higher than 40%, the aged binder in R 2 AP created a significant change in the mixture properties. All the mixtures showed an increase in energy loss with an increase in R 2 AP percentages. The higher energy loss in the R 2 AP mixture indicated a higher possibility of moisture-induced damage. There should be a limit on percent R 2 AP that could be incorporated into HMA.
