Standard Method of Test for
Indirect Tensile Test Device
AASHTO Designation: T 322-07
SCOPE
1.1.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.
1.2.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 of38 mm or less.
Specimens shall be 38 to 50 mm high and 150 ± 9 mm in diameter.
1.3.This test may involve hazardous materials, operations, and equipment.
This standard does not purport to address all of the safety concerns associated with its use.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use.
