Standard: 1.5-2" overlay, 3-4" new driveway
Average: $80-$150 per ton (varies by location)
How to Calculate Asphalt
Volume Formula
Formula: Volume = Length × Width × Thickness
Example (20' × 50' × 3"):
- Area: 20 × 50 = 1,000 sq ft
- Thickness: 3" = 0.25 feet
- Volume: 1,000 × 0.25 = 250 cubic feet
- Cubic Yards: 250 ÷ 27 = 9.26 cubic yards
- Tons: 9.26 × 1.96 = 18.2 tons
Asphalt Types & Densities
- Standard Hot Mix: ~1.96 tons/cu yd - Most common for driveways
- Dense Grade: ~2.1 tons/cu yd - High traffic areas
- Porous/Permeable: ~1.75 tons/cu yd - Allows drainage
Thickness Recommendations
- Residential Driveway (new): 3-4 inches
- Residential Driveway (overlay): 1.5-2 inches
- Commercial Parking Lot: 4-6 inches
- Road Surface: 2-3 inches (surface layer)
Cost Considerations
- Material: $80-$150 per ton
- Installation: $4-$8 per sq ft
- Base Preparation: Additional if needed
Installation Tips
- Ensure proper base preparation and drainage
- Compact base thoroughly before paving
- Roll while asphalt is still hot
- Allow 24-48 hours before driving on new pavement

Asphalt Volume Formula
Rectangular Area
Formula:
Volume = Length × Width × ThicknessExample (20' × 50' × 3"):
- Area: 20 × 50 = 1,000 sq ft
- Thickness: 3" = 0.25 feet
- Volume: 1,000 × 0.25 = 250 cubic feet

- With 5% compaction: 19.1 tons
Asphalt Types & Densities
| Asphalt Type | tons/cu yd | Density | Best Use |
|---|---|---|---|
| Standard Hot Mix | 1.96 | ~145 lb/cu ft | Residential driveways |
| Dense Grade | 2.1 | ~156 lb/cu ft | High traffic areas |
| Porous/Permeable | 1.75 | ~129 lb/cu ft | Drainage applications |
Thickness Recommendations
| Application | Thickness | Base Required |
|---|---|---|
| Residential Driveway (new) | 3-4 inches | 6-8" crushed stone |
| Residential Overlay | 1.5-2 inches | Existing surface |
| Commercial Parking | 4-6 inches | 8-12" aggregate base |
| Road Surface Layer | 2-3 inches | Base layer below |
| Tennis Courts | 2-3 inches | Stone base |
Cost Considerations
- Asphalt Material: $80-$150 per ton
- Installation: $4-$8 per square foot
- Base Preparation: $1-$3 per sq ft (if needed)
- Removal of Old Surface: Additional cost
- Sealcoating: $0.15-$0.25 per sq ft (every 2-3 years)
Installation Process
- Site Preparation: Clear area, grade for drainage
- Base Installation: Install and compact gravel base
- Edge Restraints: Install edging if needed
- Asphalt Delivery: Hot mix delivered at 275-300°F
- Spreading: Spread evenly with paver or rake
- Compaction: Roll while hot with vibratory roller
- Cooling: Allow to cool before use
Asphalt Maintenance Tips
- Wait 24-48 hours before driving on new asphalt
- Sealcoat every 2-3 years to protect surface
- Fill cracks promptly to prevent water damage
- Avoid sharp turns with vehicles on hot days
- Keep heavy trucks off residential driveways
Asphalt vs. Concrete Comparison
| Factor | Asphalt | Concrete |
|---|---|---|
| Initial Cost | $4-$8/sq ft | $6-$12/sq ft |
| Lifespan | 15-20 years | 25-40 years |
| Maintenance | Sealcoat every 2-3 years | Seal joints, occasional resurfacing |
| Repair Ease | Easy to patch | More difficult |
| Cure Time | 1-2 days | 5-7 days |
