• Abstract:
  The objective of this 2007 limited laboratory research project was to determine the potential of reducing the oxidation rate of HMA pavements by adding lignin to the asphalt binder used to produce the HMA mixture. The testing matrix for this study consisted of two binders, two basic aggregate mixtures, and one hardwood lignin at one concentration. Eight total mixtures with and without lignin were tested after long-term aging to determine if the lignin had any effects on the material properties. The test results from this project showed minimal differences between the lignin test specimens and the control specimens.
