AB-3, Sand and Gravel Delivery in Brown County, KS
Kansas Rock Supply handles gravel, stone and aggregate delivery in Brown County, KS. AB-3 is the base material here, and it is the right starting point for most drive and pad work.
The ground across the Glaciated Region of northeast Kansas puts clay subsoil under glacial drift and loess. That clay holds water, so a drive or pad over it needs a base that will not pump or rut when the ground stays wet.
Ground Conditions Across Brown County
Base, drive and paver work across the Glaciated Region of northeast Kansas runs from the time frost leaves the ground in spring through late fall. Wet spring weeks and frozen winter ground both stop compaction.
Clay subsoil under the drift drains slowly, so water stands on drives and pads. Loess bluffs shed runoff quickly onto the flat ground below, which is why bare slopes and roadside banks gully fast after heavy rain.
Cold winters with repeated freezing and thawing heave gravel drives and soften them as the ground thaws from the top down. Frost depth in Kansas is set by each city or county rather than by a statewide table.
Materials Delivered in Brown County
AB-3 is the Kansas name for dense-graded crushed limestone base: crushed rock and fines together, graded roughly 1 1/2 inch down, that locks up tight when it is moisture-conditioned and rolled.
City and county work references the same class, so AB-3 is the term a Kansas contractor uses when ordering base. It goes under driveways, parking pads, shed and shop bases and road shoulders.

Choosing the Right Material
Atchison County, Jackson County and Nemaha County all sit in the Glaciated Region, and each shares the same ground as Brown County: glacial drift over Pennsylvanian and Permian limestone and shale, with thick windblown loess on the uplands and clay subsoil under the valley alluvium.
Because the ground is the same, the choice comes down to the job rather than the county line. A drive or pad wants AB-3 under it, since the fines bind and the clay below will not drain on its own.
Where water has to move, switch to clean stone. Use 1 inch clean or 3/4 inch crushed stone for French drains, foundation drains and pipe bedding, because washed stone leaves the voids open.
Where the surface has to be walked on or bedded, use screenings, mason sand or Natural Pea Gravel. Screenings bed pavers and flagstone, while Natural Pea Gravel suits walkways, play areas and dog runs.
For slope and bank work, rip rap is the coarse stone that armours a bank against runoff. Loess cuts easily and washes easily, so bare banks need that protection before the next heavy rain.
