Refers to a gradation that is near the FHWA's 0.45 power curve for maximum density. The most common HMA mix designs in the U.S. tend to use dense graded aggregate. Typical gradations are near the 0.45 power curve but not right on it. Generally, a true maximum density gradation (exactly on the 0.45 power curve) would result in unacceptably low VMA.
