• Abstract:
  This study examined the variations found in recycled asphaltic concrete mix based upon plant quality control data and verification testing. The data was collected from four recycled hot-mix projects constructed in 1981. All plant control and acceptance data was statistically analyzed. Samples of recycled hot mix and reclaimed material were tested and analyzed in the research laboratory to resolve possible conflicts in the plant data. The recycled asphaltic concrete variation was examined with respect to that of the state's conventional asphaltic concrete. Additionally, the quality of the recycled mix's asphalt cement as measured by absolute viscosity was examined with respect to a predictive equation. It was found that variations in recycled mixtures were similar to those of conventional hot mix for all control and acceptance testing. The quality of the asphalt cement in the recycled mix was similar to results anticipated by the prediction equation.
