To use the Aggregate Calculator:

  • enter the width, length, and thickness of your job, 
  • select the thickness in feet or inches
  • click on either Base Rock, Drain Rock, or a custom density selection
    The Base Rock and Drain Rock selections will fill in the density of the rock for you; the Custom selection allows you to enter a rock density in the Density field.
  • click on the Calculate button

The calculator will estimate the number of tons of aggregate that will be required.
