          Premix - ADT >1000pcu
          •    Asphaltic concrete - graded aggregate and bitumen

          •    Bituminous Macadam - continuously graded aggregate, filler (Portland cement,
               hydrated lime, fly ash, quarry dust)


          Non premix - ADT <1000pcu

          •    Cold Fine asphalt - lime aggregate, medium to high penetrated cutback bitumen
          •    Dry sand mix - mixture of sand, clay, gravel < 1”

          •    Wet sand mix - mixture of sand, binder (SRO @ low viscosity cut back), filler Portland
               cement @ hydrated lime)
