• Abstract:
  The aggregate blended DFT value provides a good indication of the skid resistance of the corresponding mixture or pavement surface. A higher aggregate blended DFT implies a higher skid resistance for a given gradation or mixture type. According to the findings, the recommendations are as follows: • The measured RAP aggregate DFT was suggested to be employed to develop the RAP material SAC rating criteria. • The minimum required DFT values for RAP aggregate and blended aggregate were determined and recommended. • Accordingly, the preliminary criteria and guidelines for determining the blended aggregate SAC were proposed. • The proposed criteria and guidelines provide a quantitative way to evaluate and compare the aggregate and mixture skid resistance.
