  • HMA Mix Design Fundamentals – Pavement Interactive

    Aggregate gradation. Gradations with excess fines (especially in the to mm (No. 30 to 50) size range when using natural, rounded sand) can cause a tender mix. A gradation resulting in low VMA or excess asphalt binder content can have the same effect. Gradation specifiions are used to ensure acceptable aggregate gradation.
