The test method applies to which range of asphalt mixture types?

• A. Dense HMA only
• B. Open graded HMA only
• C. All HMA mixture types, including open graded and SMA
• D. SMA only

Answer: (C)

This test method is built to assess properties that are common to all hot mix asphalt types, not just one specific type. Dense HMA, open-graded HMA, and SMA differ in their gradation and internal structure, but the way we prepare specimens, apply the standard testing procedure, and interpret the results remains fundamentally the same. That consistency lets the same method be used across the full range of HMA mixes, with adjustments only to parameters like target air voids or compacting effort as needed for each type. So, the method provides a universal approach that works for dense, open-graded, and SMA mixtures alike.
