• Abstract:
  This Technical Brief provides an overview of the binder parameter Delta Tc (ΔTc). Delta Tc is an indicator of the effect of aging and additives on the asphalt rheology. More specifically, ΔTc provides insight into the relaxation properties of an asphalt binder that can contribute to non-load related cracking or other age-related embrittlement distresses in an asphalt pavement. This Technical Brief provides information for responsible deployment of the ΔTc as a specification parameter should State DOTs be considering implementation.
