Frequently Asked Questions
How thick should asphalt be for a driveway?
Residential driveways typically need 2-3 inches of asphalt over a 6-8 inch gravel base. Commercial parking lots require 3-4 inches. Heavy-traffic roads need 4-6 inches or more. Proper base preparation is as important as asphalt thickness for long-term durability.
How much does asphalt weigh?
Hot mix asphalt weighs approximately 145 pounds per cubic foot, or about 2 tons per cubic yard. A typical driveway (20x40 feet, 2 inches thick) requires roughly 3 tons of asphalt. Weight varies slightly by mix design and aggregate type.
How much does an asphalt driveway cost?
Asphalt costs $3-$7 per square foot installed, or $2,500-$10,000 for a typical two-car driveway. Material alone is about $100-$150 per ton. Costs vary by region, site prep needed, thickness, and whether existing pavement needs removal. Getting 3+ quotes is recommended.
