It's easy to determine your needs with Stout Trucking’s Aggregate Calculator.
Simply enter the width, length, and thickness of your job, then click on whether you are measuring the thickness in feet or inches. Next, click on either Base Rock, Drain Rock, or select and enter a Custom density selection. The Base Rock and Drain Rock selections will fill in the density of the rock for you.
For example, a driveway measuring 100-feet long and 9-feet wide, the typical choices are either of the following:
- Base Rock is commonly used for a new driveway on virgin ground over grass, requiring a depth of 4 inches for stability.
- Drain Rock is commonly used for an existing driveway over loose gravel/stone, requiring a depth of 2 inches.
The Custom selection allows you to enter a rock density value in the Density field.
Finally, click on the Calculate button to estimate the number of tons of aggregate that will be required for your job.
