Asphalt Calculator
Calculate asphalt quantity, weight, and cost for driveways, parking lots, and road projects
Calculate Asphalt Requirements
Length of the area to be paved
Width of the area to be paved
Typical thickness: 5-10cm (2-4 inches) for driveways, 7.5-15cm (3-6 inches) for parking lots
Asphalt Properties
Standard range: 2,200-2,400 kg/m³ (138-150 lb/ft³)
Choose preferred weight unit for results
Asphalt Requirements
Calculation: Volume = 0.00m × 0.00m × 0.000m = 0.000 m³
Weight: 0.000 m³ × 2400 kg/m³ = 0.0 kg (0.00 tonnes)
Cost Estimation (Optional)
Typical range: $80-200 per tonne
Project Analysis
Example Calculation
Residential Driveway Project
Dimensions: 7m × 6m × 5cm thick
Area: 7m × 6m = 42 m²
Volume: 42 m² × 0.05m = 2.1 m³
Density: 2,300 kg/m³ (standard asphalt)
Weight Calculation
Weight = Volume × Density
Weight = 2.1 m³ × 2,300 kg/m³
Weight = 4,830 kg (4.83 tonnes)
Cost Estimate
Cost per tonne: $120
Total cost = 4.83 tonnes × $120/tonne
Total cost = $579.60
Asphalt Types
Hot Mix Asphalt (HMA)
2,400 kg/m³ - Most durable, highways
Warm Mix Asphalt (WMA)
2,350 kg/m³ - Eco-friendly option
Cold Mix Asphalt
2,200 kg/m³ - Repairs, temporary
Blacktop
2,300 kg/m³ - Residential driveways
Thickness Guidelines
Installation Tips
Prepare stable base with crushed stone
Clear area of debris and vegetation
Ensure proper drainage slope
Compact asphalt properly after laying
Seal edges to prevent water infiltration
Apply sealer after curing for durability
Understanding Asphalt Calculations
What is Asphalt?
Asphalt is a composite material made of aggregates (stones, sand, gravel) bound together with bitumen, a sticky petroleum-based substance. It's flexible when cured, making it ideal for surfaces that experience thermal expansion and contraction.
Why Accurate Calculation Matters
- •Prevents material shortage or costly excess
- •Ensures proper thickness for load-bearing capacity
- •Helps budget accurately for project costs
- •Ensures structural integrity and longevity
Calculation Formula
Volume: Length × Width × Thickness
Weight: Volume × Density
Cost: Weight × Price per Unit
- Standard Density: 2,400 kg/m³ (150 lb/ft³)
- Range: 2,200-2,400 kg/m³
- Blacktop: ~2,300 kg/m³ (less dense)
- High-grade: ~2,400 kg/m³ (more durable)
Safety Note: Always consult with professionals for structural applications. Proper base preparation and installation are critical for longevity.
