May 31, 2019  Generally a standard asphalt mix is called Hot Mix Asphalt (HMA) or dense graded asphalt. The roadway is ground down and paved over. The HMA, made up of a mix of sand, oil and aggregate stone between 3/8- to ½-inch in size, is poured on the road. It gets heated, pressed down and rolled into that smooth surface we all know and love.
