Asphalt Tonnage Conversion Guide

Converting between asphalt area measurements and tonnage is essential for accurate material ordering. This guide provides quick reference tables and formulas to help you determine exactly how much asphalt you need by weight.

Quick Reference: Asphalt Coverage by Thickness

Thickness Coverage per Ton Tons per 1000 ft²
1 inch (25mm) 160 ft² (15 m²) 6.25
1.5 inches (38mm) 107 ft² (10 m²) 9.35
2 inches (50mm) 80 ft² (7.5 m²) 12.5
2.5 inches (63mm) 64 ft² (6 m²) 15.6
3 inches (75mm) 53 ft² (5 m²) 18.9
4 inches (100mm) 40 ft² (3.7 m²) 25

Asphalt Tonnage Formulas

Metric Formula:

Tonnes = Area (m²) × Thickness (m) × Density (kg/m³) ÷ 1000

Hot Mix Asphalt density ≈ 2400 kg/m³

Example: 100m² × 0.05m × 2400 ÷ 1000 = 12 tonnes

Imperial Formula:

Tons = Area (ft²) × Thickness (ft) × Density (lb/ft³) ÷ 2000

Hot Mix Asphalt density ≈ 150 lb/ft³

Example: 1000ft² × (3÷12)ft × 150 ÷ 2000 = 18.75 tons

Quick Approximation:

Tons ≈ Area (ft²) × (Inches ÷ 12) × 0.075

Example: 1000ft² × (3÷12) × 0.075 = 18.75 tons

Asphalt Density by Type

Different asphalt types have varying densities, which affects tonnage calculations:

Asphalt Type Typical Density (kg/m³) Typical Density (lb/ft³)
Hot Mix Asphalt (HMA) 2400 150
Warm Mix Asphalt (WMA) 2350 147
Stone Matrix Asphalt (SMA) 2450 153
Open-Graded Friction Course 2100 131
Cold Mix Asphalt 2200 137
Recycled Asphalt Pavement 2250 140

Asphalt Tonnage Calculator FAQ

How accurate is this asphalt tonnage calculator?

Our asphalt tonnage calculator is accurate to within approximately 5-10% when all measurements and density values are entered correctly. For even greater precision, you can adjust the density value based on your specific asphalt mix and add an appropriate wastage factor to account for compaction and material loss during installation.

How much does a cubic yard of asphalt weigh?

A cubic yard of hot mix asphalt typically weighs between 2.025-2.25 tons (4,050-4,500 pounds). This can vary based on the specific mix design and aggregate used. For precise calculations:

  • Hot Mix Asphalt: approximately 2.025 tons per cubic yard
  • Warm Mix Asphalt: approximately 1.98 tons per cubic yard
  • Cold Mix Asphalt: approximately 1.85 tons per cubic yard

What wastage factor should I use for asphalt tonnage calculations?

For most projects, a wastage factor of 5-10% is appropriate. Use 5% for large, simple areas with good access and professional installation. Use 10% for complex shapes, difficult access, or DIY projects. For very intricate projects or situations with challenging logistics, consider using up to 15% wastage factor.

How do I convert between tons and tonnes?

To convert between US tons and metric tonnes:

  • 1 US ton = 0.907 metric tonnes
  • 1 metric tonne = 1.102 US tons

Our calculator can automatically perform these conversions based on your selected units.

Why do I need to specify asphalt type for tonnage calculations?

Different asphalt types have different densities, which directly affects the tonnage calculation. Hot mix asphalt is typically denser than cold mix asphalt, for example. Specifying the correct asphalt type ensures our calculator uses the appropriate density value (kg/m³ or lb/ft³) for your specific material, resulting in more accurate tonnage estimates.
