What are the units for measuring specific weight?
Specific weight is a substance's weight (not mass) per unit volume. If you take a known volume of something -- say a cubic foot of it -- and place it on a scale, you know how much it weighs per cubic foot. So, let's say you have a cubic foot of water. Although its weight will vary somewhat with temperature, its average SW is about 62.4 pounds per cubic foot. Compare that to gasoline at 42.5 pounds per cubic foot and...

How do you calculate hot mix asphalt by the ton to square feet covering an area 20x20 9 inches thick?
Calculate the volume of mix needed by multiplying 20x20x9. This gives cubic inches. Then divide that answer by 144 cubic inches per cubic foot, and you have the volume in cubic feet. A cubic foot of asphalt is a different weight depending on the weight of the rock in contains, but let's 158 pound of asphalt hotmix per cubic foot. Multiply the volume in cubic feet, above, by 158lbs, and you have the weight of mix per 20x20x9. Divide the answer by...
How do you convert lb per cubic foot into tons?
You can't-lb per cubic foot is a measurement of pressure, tonnes is measure of weight. You could convert Ib per cubic foot to tonnes per cubic foot or more usually, gram per cubic centimetre but not lb per cubic foot to tonnes ...

What is the weight per cubic foot of crushed concrete roadbase?
The weight varies depending on the size of the crushed concrete. Large pieces typically have a calculated weight range of 120 to 130 lbs per cubic foot (i.e. rip rap, rubble) while smaller pieces have a calculated weight range of 135 to 145 lbs per cubic foot (i.e roadbase, soil stabilizer). The reason for the difference is that a cubic foot of large aggregate is not as dense and small aggregate because large aggregate does not compact as tightly as the...
