typical weight of asphalt
NAPA estimates an average asphalt density of 145 pounds per cubic foot, or 3,915 pounds per cubic yard. For example, if your calculated volume is 25 cubic yards, multiplying 25 by 3,915 will give you an asphalt weight per cubic yard of 97,875 pounds, or about 49 tons.1  Tape measure.. Convert cubic feet to cubic yards. Because there are 27 cubic feet per cubic yard, you will divide your total cubic feet by 27. This gives you the volume of asphalt you will need.
