WebJan 6, 2016 · Most ready-mix concrete producers use their own methods, hire a testing lab, or rely on a vendor. These methods often include a concept of “ideal gradation.”. From Fuller’s maximum density curve, the .45 power curve, 8-18, gap grading to the latest “tarantula,” the aggregate gradation has a major impact on performance. WebTypical 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. Gap Graded Refers to a gradation that contains only a small percentage of aggregate particles in the mid-size range. The curve is flat in the mid-size range.
