#4 Crushed Stone in New Mexico

Rough, angular #4 Crushed Stone maintains open spaces instead of forming a tight surface. That behavior fits drainage work and heavy support courses where water must move freely through the aggregate. Caliche hardpan can send monsoon water sideways across a grade, so runoff management deserves attention around traffic areas and erosion-prone ground.

Near arroyos or along the Rio Grande Valley, this material can help with erosion-control work where substantial water flow is expected. Its crushed shape also helps it resist shifting under heavy loads. For a traffic area exposed to seasonal runoff, use this stone below a finer compacting course rather than as the finished driving surface. Keep the aggregate placement out of the active flow line where runoff could carry loose rock away.

Heavy-Duty Base

Use it below drive lanes and hard-worked surfaces to build a stable support layer.

Erosion Control

Set larger rock at arroyo edges, grades, and drainage runs to reduce monsoon washouts.

High-Volume Drainage

The wide spaces between pieces let high runoff volumes drain away fast.

Gabion Fill

A useful rock size for gabion baskets and retaining features.

Strong Drainage

Open space around the stone gives heavy runoff a route through.

Load Bearing

Helps maintain the base when equipment and vehicles travel over it.

Erosion Control

Angular stone resists shifting on slopes during runoff.

Durable Base

Builds a foundation course meant to hold up over time.
