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.
Know MoreTo 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.
Learn more about Building MaterialsThe amount of concrete needed for a 10-by-20-foot slab depends on the thickness of the slab. A 10-by-20-foot slab with a thickness of 4 to 8 inches requires 2.5 to 5 yards of concrete.
Full Answer >Figure out the amount of concrete to use by calculating the volume of the desired concrete slab and the footings supporting the slab, then converting this area to cubic yards. The method for calculating the volume of concrete needed for slabs is also used for any concrete structure.
Full Answer >Asphalt is a thermoplastic substance that results from petroleum refinement techniques. Because asphalt derives from petroleum processing after kerosene, gasoline and naphtha have already been removed, its composition is influenced by the residue of each and the make-up of the particular type of crude oil used in that processing plant.
Full Answer >The different types of asphalt are perpetual pavement, porous asphalt, quiet asphalt, hot mix asphalt and warm mix asphalt. Asphalt is a paving material commonly used in driveways, parking lots, roads and runways.
