Order AB-3 and Crushed Stone in Johnson County, KS
Kansas Rock Supply handles gravel, stone and aggregate delivery in Johnson County, KS for contractors and homeowners alike. Some buyers are building a shop pad or a new drive, and some are topping a drive that has gone soft.
Either way, AB-3 is the base material to start with here.
Materials delivered in Johnson County
Base material comes first, then washed stone, then sand, then soil and decorative rock. Each one has a job it does well.
Base and driveway material
AB-3 is dense-graded crushed limestone with the fines left in, graded roughly 1 1/2 inch down.
It goes under drives, parking pads, shed and shop bases and road shoulders.
1 Inch Minus is the smaller dense-graded stone. It tops a drive, patches soft spots and builds up shoulders where a full AB-3 base is more than the job needs.
Driveway Gravel surfaces an existing drive or tops a compacted AB-3 base.
Washed stone and drainage rock
Kansas suppliers sell clean washed limestone by inch size, so buyers here say 1 inch clean or clean rock. 1 Inch Clean goes in French drains, foundation drains, pipe bedding and construction entrances.
3/4" Crushed Stone suits drainage beds, drive surfacing over a compacted base and trench backfill. Screenings are the crusher fines left after limestone is screened, and they bed pavers and flagstone.
Sand, soil and decorative rock
Mason Sand serves brick and block work, paver joints, sandboxes and volleyball courts. Washed Sand beds and levels under slabs and pavers, and much of it comes out of the Kansas River valley.
Top Soil builds new lawns and beds over heavy clay or thin rocky ground. Kansas River Rock, which locals call Kaw River rock, is rounded washed gravel for beds, borders and dry creek beds.
Choosing the right material
Johnson County sits in the Osage Cuestas and the eastern Kansas clay country, and so does Douglas County and Miami County. The ground is the same across all three, so the base and drainage choice does not change when a job crosses a county line.
Wyandotte County is the exception. Its ground is the Glaciated Region of northeast Kansas, where glacial drift sits over limestone and shale and thick windblown loess covers the uplands.
That loess and drift drain differently from shale-derived clay, so a base that performs over clay is not automatically the right call there. For Johnson County work, plan for clay and for water that moves slowly through it.
Ground conditions across Johnson County
Across the Osage Cuestas and the eastern Kansas clay country, heavy clay soils weathered from Pennsylvanian shale sit between limestone-capped ridges. Johnson County's own residential foundation guideline describes a predominance of clay soils with varying expansive characteristics.
Shale-derived clay takes water very slowly, so it perches on the surface. A drive laid straight on clay pumps fines up into the surface course, which is why a compacted AB-3 base matters more here than the stone on top of it.
Heavy spring and early summer thunderstorms wash unbound surfaces off the cuesta slopes. RipRap and large river rock arm stream banks, pond banks, ditch lines and culvert outlets against that runoff.
Clay works best when it is neither saturated nor bone dry. Late spring and early fall are the steadiest weeks for base work, since spring rain and the cracking of high summer are both awkward.
Winters bring repeated freezing and thawing on top of a clay that swells when wet and shrinks when it dries, so the ground moves through the year as well as through the winter. Frost depth is commonly about 36 inches around Kansas City and Johnson County, and the local building department sets the figure.

Questions about Johnson County aggregate
What is the difference between topsoil and fill dirt?
Topsoil is the screened surface layer that carries organic matter, and it goes on new lawns, beds and levelling work. Fill dirt is a structural material for raising grade, backfilling and building up low spots before a base course goes down.
Fill dirt is not a growing medium, so it belongs under the soil, not in place of it.
What is AB-3 and what is it used for in Johnson County?
AB-3 is the Kansas name for dense-graded crushed limestone base, crushed rock and fines graded roughly 1 1/2 inch down.
It goes under driveways, parking pads, shed and shop bases and road shoulders.
How deep should a gravel driveway base be in Johnson County?
That depends on your ground, your traffic and what the drive is carrying, so we do not quote a single figure. Start from the clay and the drainage on your site, then size the load on the product page calculator before you order.
Frost depth here is commonly about 36 inches, and the local building department sets the figure.
