Frequently Asked Questions

Common questions about asphalt calculation and installation

How accurate are the tonnage calculations?

Our calculations use industry-standard density values and are accurate within 2-3% of actual requirements. We account for different asphalt mixes and include waste factor recommendations based on project type.

What's included in the waste factor?

The waste factor accounts for compaction loss, spillage during transport, edge trimming, and irregular surfaces. We recommend 5-10% for most projects, with higher percentages for complex shapes or first-time contractors.

Can I use this for different types of asphalt mixes?

Yes! Our calculator supports various asphalt densities from 140-150 lb/ft³, covering standard hot mix, dense-graded, and specialty mixes. You can also input custom density values for specific applications.

How do I determine the right thickness for my project?

Thickness depends on traffic load and soil conditions. Residential driveways typically need 2-3 inches, commercial parking lots 3-4 inches, and heavy-duty applications 4-6+ inches. Consult local building codes for specific requirements.

What about base material calculations?

Our calculator includes crushed stone base estimates (4-8 inch thickness range). Proper base preparation is crucial for asphalt longevity. The base should be compacted to 95% standard Proctor density.

Can I save and share my calculations?

Yes! You can generate professional PDF reports with all calculations, cost estimates, and project details. These reports are perfect for client presentations, permit applications, and contractor bids.
