How Asphalt Calculator California Works
Visual calculation flow
L × W sq ft
→ × Thickness in ÷ 12
→ Climate Zone PG Binder
→ Result tons
Tons = Area (sq ft) × Thickness (in) ÷ 12 × 145 ÷ 2000 Step 1: Enter length and width in feet to calculate area in square feet.
Step 2: Enter thickness in inches. Divided by 12 to convert to feet for volume.
Step 3: Select your climate region. California has 4 zones with different PG binder requirements (Coastal, Valley, Desert, Mountain).
Step 4: Volume × 145 lb/ft³ density ÷ 2000 = US tons. Recommended Caltrans binder grade is displayed.
California Asphalt Calculator FAQs
What Caltrans specifications apply to California asphalt?
Caltrans requires HMA (Hot Mix Asphalt) mixes meet specific specifications based on climate region. PG 64-10 is common for coastal areas, PG 64-16 for valleys, and PG 76-22 for desert regions. All state highway work must use Caltrans-approved mixes and certified contractors.
How much does asphalt cost in California?
California asphalt prices are among the highest in the US due to environmental regulations and high demand. Expect $100-$150 per ton for material (2024). Installed driveway costs range from $4-$8 per square foot. LA, SF Bay Area, and San Diego tend to have higher prices than Central Valley and rural areas.
Do I need permits for asphalt work in California?
Most California cities require permits for new driveways or significant paving work. This includes curb cuts, drainage modifications, and commercial projects. Resurfacing existing driveways typically doesn't require permits. Check with your local city building department - requirements vary by municipality.
How does California's climate affect asphalt choice?
California's diverse climate zones require different PG grades. Coastal (mild): PG 64-10. Central Valley (hot summers): PG 64-16 or PG 70-10. Desert (extreme heat): PG 76-22 with polymer modification. Mountain (freeze-thaw): PG 58-22 or PG 64-22. Using the wrong grade leads to premature failure.
