Asphalt Weight Calculator:
Enter the values of area, A(ft2) and asphalt density, AD(lbs/ft3) to determine the value of Weight of asphalt, AW(lbs).
Asphalt Weight Formula:
The physics of asphalt weight revolves around the relationship between the material’s density, area, and thickness. Asphalt, a composite material commonly used in road construction, is composed of aggregates like sand, gravel, and crushed stone, bound together by bitumen.
The weight of asphalt depends on its density, which is influenced by the composition and compaction level of the material.
Density plays a crucial role in determining how much asphalt is required to cover a given area. The higher the density, the heavier the asphalt will be for the same volume. The weight of asphalt is directly proportional to the area it covers and its thickness.
As the area increases, or the thickness of the asphalt layer increases, the overall weight of the material also increases.
Weight of asphalt, AW(lbs) in pounds is calculated by multiplying the area, A(ft2) in feet square by the asphalt density, AD(lbs/ft3) in pounds per cubic foot and then dividing by the factor 12 (which converts inches to feet), followed by multiplying by 145 to account for the standard density.
Weight of asphalt, AW(lbs) = (A(ft2) * AD(lbs/ft3) / 12 ) * 145
AW(lbs) = weight of asphalt in pounds, lbs.
A(ft2) = area in square feet, ft2.
AD(lbs/ft3) = asphalt density in pounds per cubic foot, lbs/ft3.
Asphalt Weight Calculation:
- A parking lot has an area of 500 square feet. The density of the asphalt used is 145 pounds per cubic foot.
Given: A(ft2) = 500ft2, AD(lbs/ft3) = 145lbs/ft3.
Weight of asphalt, AW(lbs) = (A(ft2) * AD(lbs/ft3) / 12 ) * 145
AW(lbs) = (500 * 145 / 12) * 145
AW(lbs) = 876041.6lbs.
- Determine the Area Covered by 5000 Pounds of Asphalt:
Given: AW(lbs) = 5000lbs, AD(lbs/ft3) = 145lbs/ft3.
Weight of asphalt, AW(lbs) = (A(ft2) * AD(lbs/ft3) / 12 ) * 145
A(ft2) = AW(lbs) *12 / AD(lbs/ft3) * 145
A(ft2) = 5000 * 12 / 145 * 145
A(ft2) = 1034.48ft2.
