how many square feet in one ton of asphalt?
The density of asphalt is generally given at 140 lbs per cubic foot (I have assumed you would like this in imperial as you use feet) At that density a ton ( 2240 lbs) is 16 cubic feet so it now comes down to how thick you want the coating, at 1 inch thick the ton will cover 12 x 16 (192) square feet.
