Frequently Asked Questions

What is road base gravel?

Road base (also called crusher run, dense-graded aggregate, or DGA) is a mixture of crushed stone and stone dust that compacts into a very solid, stable surface. Ideal for driveways and sub-bases.

How deep should road base be?

4 inches for residential driveways; 6 inches for commercial driveways and heavy equipment; 8–12 inches for road construction. Compact in layers.

What is the difference between road base and crushed stone?

Road base contains both crushed stone AND stone dust (fines). The fines fill voids and allow it to compact like concrete. Pure crushed stone lacks fines and stays looser.

How much does road base cost?

Road base typically costs $10–$30 per ton — usually cheaper than other gravels because it's less processed. Delivery is typically $50–$150 extra.
