• Abstract:
  The objectives of this research study was to prepare a series of crumb and powdered rubber blends with Louisiana asphalts and assess the compatibility and stability of each blend. The research was also to evaluate the potential for applying dynamic testing techniques to asphalt/rubber blends. The survey included determination of rheological parameters, high temperature viscosity, and creep. Last but not the least, the research was to wubject the rubber asphalt blends to both TFOT and PAV aging to determine the hardening characteristics and compatibility of the blends during accelerated aging.
