Construction and Materials
Asphalt Calculator
Estimate compacted asphalt volume, weight, purchase quantity with waste, truckloads, and material cost for a rectangular area.
Formula
Volume ft^3 = length x width x depth / 12; tons = volume x compacted density / 2,000.
About the Asphalt Calculator
Estimate compacted asphalt volume, weight, purchase quantity with waste, truckloads, and material cost for a rectangular area.
How the Asphalt Calculator Works
Pavement dimensions are converted to cubic feet, multiplied by the user-entered compacted density, then increased by waste before cost and truckload rounding.
Formula
Volume ft^3 = length x width x depth / 12; tons = volume x compacted density / 2,000.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Paved length (required) - enter in ft.
- Paved width (required) - enter in ft.
- Compacted depth (required) - enter in in.
- Compacted asphalt density (required) - enter in lb/ft3.
- Waste allowance (required) - enter in %.
- Truck capacity (required) - enter in tons.
- Material cost per ton (required).

Accuracy and Limitations
Compacted density, lift thickness, base preparation, compaction, irregular geometry, and supplier minimums vary. Confirm tonnage and delivery constraints with the supplier.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
