Frequently Asked Questions
How is hot-mix asphalt tonnage calculated?
Hot-mix asphalt weighs approximately 145 to 150 pounds per cubic foot (or 110 lbs per square yard per inch of thickness). Formula: Tons = (Area in sq ft × Thickness in inches / 12 × 145 lbs/cu ft) / 2,000 lbs/ton.
What thickness should a residential asphalt driveway be?
A high-quality residential driveway requires 2.5 to 3.0 inches of compacted hot-mix asphalt laid over a 6 to 8-inch well-compacted crushed gravel base (item 4 or 21A road bond).
When should a new asphalt driveway be sealcoated?
Wait 6 to 12 months before applying the first coat of coal-tar or asphalt-emulsion sealer. This curing period allows volatile light oils in the fresh asphalt to evaporate, hardening the binder surface.
How much does 1 bucket of driveway sealer cover?
A standard 5-gallon commercial pail of asphalt sealer covers approximately 300 to 400 square feet on rough or unsealed surfaces, or up to 500 square feet on smooth previously sealed driveways.
