Actual Concrete Mix Ratios For 3000, 3500, 4000, and 4500 ...
These concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete come from the ready mix concrete company I use to pour concrete floors, slabs, patios, pool decks, and stamped concrete. I'm going to show you the actual batch plant ticket they give me when the concrete trucks show up on the job and we pour the concrete.

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%.
