“The lane running out to our wheat fields used to turn to soup every wet spring, so we had twenty five tons of road base put down along the half mile stretch, and Kansas Rock Supply had it here within two days. The tri-axle dumped it in three spots along the lane so we could spread with the tractor blade ourselves. Held up through a wet spring this year without a single truck getting stuck.”

Loose surface rock does not provide the same support as a properly packed base. AB-3 is useful below farm roads, driveways, feedlot pads, and construction access where traffic or equipment will keep crossing the area. In eastern Kansas, expansive clay can swell in wet conditions and crack as the ground dries, while western ground may drain more readily.
AB-3 packs into a dense layer when compacted, with its varied aggregate material settling together to create structural support. Begin with prepared subgrade and compact the material before applying the finish layer above it. That approach matters after flash rain, when unworked material can shift at the surface and the soil below may lose firmness.

Common Uses
Roads and Highways
Placed below asphalt or concrete, road base forms the structural layer for road and highway work. It helps carry traffic weight across the subgrade instead of concentrating it in one area.
Heavy-Duty Driveways
Where driveways carry repeated traffic from work vehicles, trailers, or heavy trucks, road base forms a firm layer to help limit ruts and surface wear. A compacted base is especially useful after Kansas flash rains.
Access Roads at Job Sites
Use road base for temporary or permanent routes into construction sites. It supports equipment movement and provides a dependable surface during wet conditions, helping work continue after rain.
Business Parking and Loading
For commercial parking lots, loading docks, and industrial yards, road base creates the underlying support needed where vehicles and equipment see daily use.
Why Choose AB-3
Heavy Load Support
Road base can carry demanding weight from fully loaded dump trucks and industrial equipment. Once compacted, it spreads loads through the base to help avoid damage from concentrated pressure.
Road Base for Your Project
Choose the stone size and compaction your project calls for, especially where Kansas weather and loose surface rock can affect the finished layer.
Performance in Changing Weather
With proper installation, road base can retain its support through wet, dry, and freeze-thaw weather. Tight compaction helps keep water from entering and softening the base.
Economical for Large Projects
Road base offers a practical unpaved surface option for broad areas. It works well for access roads, parking areas, and work yards where a strong base is needed.

Farm lane survived the wet spring

Overflow lot survived the tractor pull
We host a tractor pull on the property every August and needed a real base for overflow parking instead of just mowed grass. Fifteen tons went down and got graded flat before the crowds showed up. Even with two days of trucks and trailers rolling over it, there wasn't a single rut left once everyone cleared out.

Turnaround Handles Two Harvests Now
Our grain truck turnaround out past Emporia used to rut up every harvest. Ten tons of road base packed in solid, and it has carried loaded trucks through two full harvests without a single soft spot.

Solid lane base, a few big chunks
Put down about eighteen tons of road base for the lane connecting the two pastures, which used to be nothing but ruts after rain. Compacted well with the tractor tire pressing it down over a few passes. A handful of chunks were bigger than I expected for base material, closer to fist size, but nothing the grader blade couldn't handle.
