Compacting Hot Mix Asphalt Pavements: Part I | Roads & Bridges
The compaction process causes the asphalt-concrete mix to be compressed and its volume reduced. As the density of the hot-mix asphalt material increases, the air-void content of the mix decreases (they are inversely proportional to each other). Properly designed, a HMA mix should have an air-void content in the range of 3% to 5%.
