What Is a American Asphalt Calculator?
The American Asphalt calculator models high-performance commercial and highway paving specifications. It utilizes calibrated aggregate density curves (~114 lbs/sq yd/in) for state DOT and municipal commercial paving standards.
How to Use This Calculator
- Enter length and width of the parking lot or road section in feet.
- Specify compacted lift thickness in inches.
- View total square yardage, required tonnage, and tri-axle delivery logistics.
- Review subgrade compaction specifications for heavy vehicle loading.
Commercial Asphalt Specification Formula
\text{Tons} = \frac{(\text{Length} \times \text{Width}) / 9 \times \text{Thickness (in)} \times 114}{2000} \times 1.05Incorporates American Asphalt premium mix density of 114 lbs per square yard inch with heavy vibratory roller compaction allowances.
Worked Example
Scenario: Paving a commercial retail parking lot section: 120 ft by 60 ft at 3 inches compacted binder course.
Square yards: (120 × 60) ÷ 9 = 800 sq yds.
Total pounds: 800 sq yds × 3 in × 114 lbs = 273,600 lbs.
Tonnage with 5% waste: (273,600 ÷ 2000) × 1.05 = 143.64 tons.
Delivery: 144 tons ÷ 20 tons/truck = ~7 to 8 tri-axle loads.
Tips & Key Notes
- For high-traffic commercial lots, install a two-lift system: 2.5" binder course plus 1.5" wearing surface course.
- Ensure proper minimum slope (1% to 2% grade) toward catch basins to prevent surface water ponding.
- Schedule trucking deliveries continuously to keep the asphalt paver moving without cold stopping joints.
Frequently Asked Questions
What is the difference between a binder course and a wearing surface course?
A binder course uses larger aggregate (0.75" to 1") for structural load support. A wearing surface course uses smaller, tighter aggregate (0.375" to 0.5") to provide a smooth, dense, water-impermeable driving surface.
How do you convert square feet of paving to square yards?
Divide the total square footage by 9. For example, 1,800 sq ft ÷ 9 = 200 square yards.
What is the recommended slope for asphalt parking lots?
A minimum slope of 1.0% (1/8 inch per foot) to 2.0% (1/4 inch per foot) is required for positive gravity drainage into storm drains.
How long does commercial asphalt paving last?
A properly engineered asphalt lot with routine sealcoating every 3–4 years has an expected lifespan of 20 to 30 years.
