Size and Grading

- Grading
- Graded mix of crushed stone, gravel and binding fines
- Type
- Crushed aggregate blend
Class 5 wears as a compacted, firm layer rather than loose surface material. Its crushed aggregate, gravel, and fines lock together under compaction, forming support for traffic and equipment. That behavior is useful beneath driveway and lake-cabin road work, where clay soils can stay wet and frost can move the ground.
Plan drainage before material is placed near lake lots, so spring melt does not flow toward the water or remain beneath the drive. Compact the base to bring the blend into close contact and support the traffic above. This material fits road, parking-area, and access-route work that faces regular heavy use.

Common Uses
Road & Highway Construction
For roads and highways, road base sits under asphalt and concrete as the support layer. It spreads traffic weight over the subgrade, an important consideration where deep frost can affect the ground below.
Heavy-Duty Driveways
Where a driveway sees heavy trucks, equipment trailers, or regular commercial use, road base supplies added support to help limit ruts and wear from demanding loads.
Construction Site Access Roads
For jobsite entry routes, road base can be placed for either short-term or lasting access. It supports equipment travel and gives crews a firm surface when wet conditions would otherwise slow the work.
Commercial Parking & Loading Areas
For sites with daily heavy vehicle or equipment traffic, road base is used beneath industrial yards, loading docks, and commercial parking lots.
Why Choose Class 5
Maximum Load Capacity
Road base supports substantial weight, including loaded dump trucks and industrial equipment. Once compacted, it spreads loads across the surface and helps reduce concentrated-load damage.
Road Base for Your Project
Choose road base with the size and material details your project requires, especially where deep frost and spring moisture affect the ground.
All-Weather Performance
When installed correctly, road base can remain stable through wet periods, dry weather, and deep frost with freeze-thaw cycling. Tight compaction helps keep water from entering the base and causing it to soften.
Economical for Large Projects
For access roads, parking areas, and work yards over a large footprint, road base offers an unpaved surface option with commercial-use support.
