Standard Method of Test for Determining Dynamic Modulus of Hot Mix Asphalt (HMA) AASHTO Designation: T 342-11 (2015)1 American Association of State Highway and Transportation Officials 444 North Capitol Street N.W., Suite 249 Washington, D.C. 20001 Standard Method of Test for Determining Dynamic Modulus of Hot Mix Asphalt (HMA) AASHTO Designation: T 342-11 (2015)1 1. SCOPE 1.1. This test method covers procedures for preparing and testing hot mix asphalt (HMA) to determine the dynamic modulus and phase angle over a range of temperatures and loading frequencies. 1.2. This standard is applicable to laboratory-prepared specimens of mixtures with nominal maximum size aggregate less than or equal to 37.5 mm (1.48 in.). 1.3. This standard may involve hazardous material, 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 procedure to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2.
