This report contains standardized baseline dat a for a series of Hot Recycling Agents and AC-3 asphalt. The hot recycling agents are identified by their RA number (RA-6, RA-25, RA-100 and RA-275) where the RA number is defined as the average viscosity of the sample at 140°F divided by 100. The recycling agents and the AC-3 have been characterized by solubility measurements to determine maltene, resin, and oil contents which have been compared to nuclear magnetic resonance (1H and 13 c NMR) and infrared (IR) spectral data. The RA numbers have been found to correlate with the resin/oil and high affinity/low affinity ratios, C-H stretching intensity ratios and 13 C-NMR intensity ratios. The data should form a basis for the identification of recycling agents.
