- Edition: 5.0
- PDF (free) Download
This test method sets out procedures for the preparation of asphalt specimens and measuring the change in indirect tensile strength resulting from the effects of moisture and freeze/thaw conditioning. The results can be used to assess the propensity for stripping of dense-graded, gap-graded and stone mastic asphalt mixes.
This test method can also be downloaded as a Word document.
Edition 5.0 published February 2022
- Reformatted
- Volume calculation clarified such that mensuration is used for swell calculations and the presaturation method for air voids calculations.
- Freeze/thaw conditioning changed from optional to a standard requirement.
- The results can be used to assess the propensity for stripping of dense-graded, gap-graded and stone mastic asphalt bituminous mixes.
- Clauses 10.1, 10.2, and 12 digital imagery requirements added.
- Clauses 10.1 and 10.2 definition of shock added.
- The subset with the lowest average air voids content shall be used for the dry subset to be tested.
