Road Base Calculator

Calculate aggregate base material needs for your construction project

Disclaimer: This calculator provides estimates only. Actual material needs may vary based on compaction, moisture content, and specific material properties. Always consult with a professional for critical projects.

Road Base Calculation Formula

Volume (yd³) = (Length × Width × (Depth/12)) / 27

Tons = Volume × Material Density

This formula helps you determine how much aggregate base material your project requires.

Why Road Base Calculations Matter:

  • Accurate estimates prevent costly over-ordering or delays from under-ordering
  • Proper base material is essential for long-lasting construction projects
  • Different projects require different types of road base (class 2, class 6, etc.)
  • Material is typically sold by the ton, while measurements are often in cubic yards

Key Insights:

Driveways

Typically use 4-6 inches of compacted road base under surface material

Road Construction

Often requires 8-12 inches of compacted base depending on traffic

How Our Road Base Calculator Works
