• Abstract:
  With the Missouri Department of Transportation (MoDOT) beginning to implement the new Mechanistic-Empirical (M-E) Design Guide for New and Rehabilitated Pavements, the need exists for various types of testing of hot-mix asphalt (HMA) mixes used by MoDOT in its flexible pavements. In particular, the American Association of State Highway and Transportation Officials (AASHTO) test protocol T 322 is utilized to determine HMA properties needed as inputs to pavement distress prediction modelswithin the M-E Pavement Design Guide (MEPDG) Software. The primary properties derived from T 322 are creep compliance and tensile strength. These properties are determined using indirect tension methods and are temperature dependent. Creep compliance is a parameter used in the thermal cracking distress model within the MEPDG Software and is determined at 0, -10, and -20°C while tensile strength is an input to the fatigue cracking distress model and is determined at temperatures ranging from -20 to +20°C.
