Kearny County, KS Gravel and Landscape Rock Delivery
Kansas Rock Supply handles gravel, stone and aggregate delivery in Kearny County, KS. AB-3 is the base material here, and it is the name a Kansas contractor uses when ordering.
AB-3 is dense-graded crushed limestone base: crushed rock and fines graded roughly 1 1/2 inch down. It goes down on driveways, parking pads, shed and shop bases and road shoulders, and locks up tight when it is moisture-conditioned and rolled.

Start with the job in front of you. A driveway, a patio and a drain each want a different material.
AB-3 and how it is specified
Aggregate base is called AB-3, and the requirements for aggregates for base construction sit in Section 1104, inside Division 1100 of the Kansas Standard Specifications.
City and county work references the same class. That makes AB-3 the term to use when ordering base for a drive or a pad.
Drainage and clean stone
Clean washed limestone moves water. 1 inch clean and 3/4 inch crushed stone suit drainage beds, pipe bedding and trench backfill.
For tighter work, 3/8 inch crushed stone handles fine drainage and paver joints. Drain Rock covers French drains, dry wells and downspout runs.
Surfaces and soil
For a finished surface, Driveway Gravel tops a compacted AB-3 base, and Walkway Gravel gives paths a finer surface underfoot.
Soil, fill and mulch round out a site. Garden soil feeds raised beds, fill dirt raises grade and backfills, and shredded mulch holds moisture in beds through a hot, windy summer.
Ground conditions across Kearny County
Kearny County spans more than one ground region. In the High Plains of western Kansas, silty loess and sandy soils sit over the Ogallala Formation of sand, gravel and cemented beds.
Cemented Ogallala is called mortar bed locally, and hard caliche layers sit close to the surface in places. Caliche will not take water, so a base laid over it needs somewhere for water to go.
In the Arkansas River Lowlands and the south-central sand prairie near Lakin and Deerfield, sand, gravel and silt were laid down by the Arkansas River, with stabilized dune sand across the prairie and a sandy loam over the top.
Rainfall runs about 15 to 25 inches a year on the High Plains, arriving in heavy summer storms. It runs to the low spots and playas, which is where unbound surfaces fail first.
Sand drains fast, which sounds like good news until a surface course with no binding fines sinks straight into it. Wind moves loose sand as soon as the cover is broken.
Both zones give a long working season. On the High Plains the difficulty is getting moisture into material and holding it long enough to compact.
In the river lowlands the limits are wet spring weeks and high summer heat.
Choosing the right material
Grant County sits on the same High Plains ground as western Kearny County: silty loess and sandy soils over the Ogallala, with mortar bed and hard caliche close to the surface. The base choice there works from the same starting point.
Finney County and Hamilton County both span more than one zone, the High Plains and the Arkansas River Lowlands with the south-central sand prairie. That is the same split Kearny County has, so the ground is the same across the line.
