# Asphalt Pro Calc - Hot Mix Asphalt Calculator & Paving Guide > Professional hot mix asphalt (HMA) tonnage, volume, and cost calculator for paving contractors, civil engineers, estimators, and homeowners. ## Overview Asphalt Pro Calc (https://asphaltprocalc.netlify.app/) is a free, browser-based civil engineering and asphalt paving estimator. It calculates exact asphalt material requirements in US Customary Tons, Metric Tonnes, Cubic Yards, and Cubic Meters, along with delivery dump truck load requirements and project budget planning. ## Key Formulas & Density Constants - Compacted Hot Mix Asphalt (HMA) Density: 145 lbs/cu ft (2,323 kg/m³) - Compacted Asphalt Yield Factor: 2.025 US Tons per Cubic Yard (0.0725 US Tons per Sq Yd per inch of compacted depth) - Imperial Tonnage Formula: Tons = [Area (sq ft) × Depth (inches) / 12] × 145 / 2000 - Quick Imperial Tonnage Rule: Tons = Area (sq ft) × Depth (inches) / 160 - Waste Factor Adjustment: Total Tons = Raw Tons × (1 + Waste Percentage / 100) - Standard Dump Truck Capacity: 20 US Tons (Tri-axle load) ## Core Tools & Calculators - [Hot Mix Asphalt Tonnage Calculator](https://asphaltprocalc.netlify.app/#calculator): Interactive tonnage, volume, truck count, and material cost calculator supporting rectangular, circular, and triangular shape options. - [How Much Asphalt Do I Need?](https://asphaltprocalc.netlify.app/how-much-asphalt-do-i-need.html): Complete mathematical guide for calculating driveway and roadway asphalt tonnage, waste allowances, and compaction rates. - [Asphalt Driveway Cost Calculator](https://asphaltprocalc.netlify.app/asphalt-driveway-cost-calculator.html): Comprehensive price guide for 2026 covering residential driveway paving costs per square foot ($3.00 - $5.00/sq ft). - [Asphalt Parking Lot Cost Calculator](https://asphaltprocalc.netlify.app/asphalt-parking-lot-cost-calculator.html): Commercial paving cost estimator, line striping, milling, sub-base stone layer, catch basins, and parking stall calculations. ## Complete Site Directory - Home & Calculator: https://asphaltprocalc.netlify.app/ - Tonnage Calculation Guide: https://asphaltprocalc.netlify.app/how-much-asphalt-do-i-need.html - Driveway Cost Calculator: https://asphaltprocalc.netlify.app/asphalt-driveway-cost-calculator.html - Commercial Parking Lot Calculator: https://asphaltprocalc.netlify.app/asphalt-parking-lot-cost-calculator.html - Paving Blog & Articles: https://asphaltprocalc.netlify.app/blog.html - About Us: https://asphaltprocalc.netlify.app/aboutus.html - Contact Us: https://asphaltprocalc.netlify.app/contactus.html - Privacy Policy: https://asphaltprocalc.netlify.app/privacypolicy.html - Disclaimer: https://asphaltprocalc.netlify.app/disclaimer.html - Sitemap: https://asphaltprocalc.netlify.app/sitemap.xml - LLM Knowledge Base: https://asphaltprocalc.netlify.app/llm.txt ## Recommended Paving Thickness Guidelines - Walkways & Bicycle Paths: 1.5 inches (3.8 cm) compacted depth - Residential Driveways: 2.0 - 3.0 inches (5.0 - 7.6 cm) compacted depth - Light Commercial Parking Lots: 3.0 - 4.0 inches (7.6 - 10.0 cm) compacted depth - Heavy Commercial & Truck Loading Docks: 4.0 - 6.0+ inches (10.0 - 15.0+ cm) compacted depth ## Contact & Support For support, feedback, partnership inquiries, or calculator feature requests, visit https://asphaltprocalc.netlify.app/contactus.html
