AASHTO T322

Standard Method of Test for Determining the Creep Compliance and Strength of Hot Mix Asphalt (HMA) Using the Indirect Tensile Test Device

This standard provides procedures for determining the tensile creep compliance at different loading times, tensile strength and Poisson's ratio of hot mix asphalt (HMA) using indirect loading techniques. The procedures described in this standard provide the data required to conduct the thermal cracking analysis. These procedures apply to test specimens having a maximum aggregate size of 38 mm or less. Specimens shall be 38 to 50 mm high and 150 ± 9 mm in diameter.
