Crusher Run Calculator: The Foundation of Your Driveway
If you are building a gravel driveway, a parking pad, or a base for pavers, the material you choose matters. **Crusher Run** (also known as ABC Stone, Crush and Run, or Quarry Process) is the gold standard for these projects. Our **Crusher Run Calculator** helps you estimate exactly how much material to order so your project starts on a solid footing.
What is Crusher Run?
Unlike "clean" stone which is just rocks of a certain size, Crusher Run is a mixture. It contains roughly:
- 3/4-inch to 1-inch stones: Provide strength and volume.
- Stone dust (Fines): Fills the voids between the larger stones.
The magic happens when you compact it. The dust locks the stones together, creating a low-void, semi-solid surface that sheds water and resists shifting under tires.
Calculating Your Needs
To find out how much you need, you first calculate the volume in cubic yards:
Length(ft) × Width(ft) × Depth(ft) / 27 = Cubic Yards
Then, because quarries sell by weight, you convert yards to tons. Crusher Run is dense because of the dust, typically weighing about 1.4 to 1.5 tons per cubic yard.
This calculator uses a conversion factor of 1.4 tons/yard, which is standard for dry limestone aggregate.
Recommended Depth
- New Driveway: 4 to 6 inches is recommended for a stable base on bare soil.
- Top Dressing: 2 to 3 inches is usually sufficient to refresh an existing gravel driveway.
Conclusion
Don't guess with expensive deliveries. Measure your area carefully and use the **Crusher Run Calculator** to order the perfect amount of aggregate for a long-lasting, durable surface.
