The waxing crescent moon is defined to occur when the Moon is nearly, but not precisely, on a line with the Earth and Sun. This means that part but less than one-half of the Moon is illuminated by direct sunlight, creating a crescent moon.
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.
Re: formula for cubic yards asphalt to tons. I found data on crushed asphalt of 45 pounds/cubic foot, and asphalt concrete at 140 pounds/cubic foot. The densities differ greatly, so would be best if you knew more closely what type of asphalt it was. Or if you have the density of your specific kind that would be best.
