Understanding the formula and key factors that affect your asphalt estimate.
Asphalt is sold and quoted by the ton. Standard HMA (hot mix asphalt) has a density of about 145 lbs per cubic foot.
Walkways/paths: 1–1.5 inches
Residential driveways: 2–3 inches
Commercial driveways: 3–4 inches
Roads (light traffic): 3–4 inches
Roads (heavy traffic): 5–6+ inches
Asphalt pricing varies by region, petroleum costs, and project size. Typical ranges:
Material: $85–$150/ton
Installation: $40–$80/ton
Residential driveway: $3–$8 per sq ft total
Always order 5–10% more than your calculated amount to account for:
• Compaction during installation
• Uneven surface variations
• Edge trimming waste
• Material spillage during delivery
Asphalt should be laid when air temperature is above 50°F (10°C). Avoid installation during rain or on frozen ground. New asphalt requires 24–48 hours before light vehicle use.
HMA (Hot Mix): Most common, good durability
WMA (Warm Mix): Lower temp, eco-friendly
Dense-graded: Highways, high traffic
Porous/Open: Water drainage applications
