Crusher Run

Gravel, rock, boulders, or blasted rock that has been reduced in size by a machine but has not been sorted for size.

Purpose

Crusher run is used as a base material for construction projects such as driveways, pathways, and under concrete slabs. It provides a stable and compactable foundation, ensuring durability and strength.

Examples of Use

1. Laying crusher run as the base layer for a gravel driveway to provide stability and support for the surface gravel.
2. Using crusher run under a concrete patio to ensure a solid and level foundation.
3. Applying crusher run in the construction of roadways to create a firm and stable base layer before the final paving.

Related Terms

• Base Course: The layer of material laid down immediately above the subgrade in pavements, providing structural support.
• Subbase: The layer of aggregate material placed on the subgrade, which provides additional support and drainage for the base course.

Notes

Crusher run is valued for its compaction properties and ability to create a solid foundation. It should be properly graded and compacted during installation to ensure maximum performance.
