How to Calculate Asphalt
- 1. Measure length and width of driveway in feet
- 2. Determine required asphalt depth (2-6 inches typical)
- 3. Calculate volume: Area × Depth ÷ 12
- 4. Convert to tons using asphalt density (145 lbs/cu ft)
- 5. Add 5-10% waste factor for cuts and overage

Installation Tips
- • Proper base preparation is critical for longevity
- • Install in dry weather with temps above 50°F
- • Compact asphalt while hot for best results
- • Wait 6-12 months before first seal coating
- • Avoid heavy traffic for 24-48 hours after paving
Frequently Asked Questions
How thick should my asphalt driveway be?
For residential driveways, 3-4 inches of asphalt is typical. Overlay projects can be 2-3 inches. Commercial driveways or those with heavy vehicle traffic should be 4-6 inches thick.
Do I need a gravel base for asphalt?
Yes, for new installations. A 6-inch compacted gravel base provides proper drainage and prevents cracking. Overlay projects on existing stable asphalt don't need additional base.
How much does asphalt cost per ton?
Hot mix asphalt typically costs $100-150 per ton, varying by region and oil prices. Installation costs range $3-7 per square foot including materials and labor.
When should I seal coat my asphalt driveway?
Wait 6-12 months after installation for the asphalt to cure. Then seal coat every 2-3 years to protect against water damage, UV rays, and oxidation.
