• Abstract:
  The Virginia Department of Transportation (VDOT) has adopted the balanced mix design (BMD) framework to enhance the durability and service life of its dense-graded asphalt surface mixtures with A and D designations. VDOT’s BMD framework incorporates the indirect tensile cracking test to assess the cracking susceptibility of asphalt mixtures through the cracking tolerance (CT) index under short-term oven-aging conditions. However, the current framework does not consider the effect of oxidative aging on asphalt mixture performance throughout its service life, which can be evaluated using long-term oven-aging (LTOA) methods.
