The area that 1 ton of asphalt covers depends on the thickness of the asphalt to be used; for a half-inch thick section of asphalt, 1 ton will cover approximately 316 square feet, while 1 ton of asphalt will cover 79 square feet when laid several inches thick. To know the exact amount of material needed, the contractor must know the compacted density of the material.
Continue ReadingTo find the exact weight of asphalt needed, multiply the compacted density by the volume required. For a 200-square foot surface at a thickness of 4 inches, the volume can be worked out by multiplying the area by the thickness, meaning that 50 cubic foot of asphalt would be required. Next, the contractor must multiply this by the density, measured in pounds per cubic foot, or PCF. For example, 50 cubic foot multiplied by a PCF of 150 would require 7,500 pounds of asphalt, or 3.75 tons.

Multiply the volume by density to determine weight and convert to tons. The calculations require a few minutes for small projects.
Full Answer >Multiply figures for length, width and thickness, measured in feet, and divide by 27 to determine the yardage of concrete required. Multiply the total yards by 1.05 to allow for a margin of error to ensure enough materials are available. With a pocket calculator and tape measure, the process takes only a few minutes.
Full Answer >To determine the number of floor tiles required to cover a given space, multiply the length by the width of the space in feet to calculate the total square footage or area, then divide that number by the size of the tile. This is easiest with 12-inch tiles, but it is possible for any size of tile.
Full Answer >To calculate how much gravel is needed, measure the width and breadth of the area in feet, and determine the depth desired. Multiply the length times the width times the depth for the number of cubic feet, then divide that number by 27 to determine the needed cubic yards.
