SB-2 Base, Sand and Gravel Delivery in Carroll County, AR
Looking for gravel, stone and aggregate delivery in Carroll County, AR? Arkansas Rock Supply sells bulk material online and delivers it to your site.
Start with SB-2 base, the dense-graded 1 1/2 inch minus crushed stone that locks up under a roller.
This is Ozark Plateaus ground, cherty clay loam over limestone and dolostone. That ground decides how a drive, pad or drain has to be built before anything is ordered.
Materials Delivered in Carroll County
What you order depends on the job in front of you. A driveway, a patio and a French drain each want a different stone, and the local names below are the ones to use.
SB-2 base and Class 7
SB-2 base is the standard Arkansas base material. It is a dense-graded 1 1/2 inch minus crushed stone with the fines left in, so it locks up under a roller and carries a drive or a pad.
Table 303-1 sets the aggregate base course gradings as Class 1 through Class 8, and Class 7 is the 1 1/2 inch dense grading sold as SB-2.
Class 8 is the 1 inch version of the same dense grading. Cities and counties write Class 7 into their own street, sidewalk and parking standards, so use that name when you are working to a written spec.
Section 302 covers select material used as a foundation course underneath. Crusher run, or dense graded base, is a finer dense-graded material that binds and compacts for drives and pads.
Drainage and decorative stone
For a French drain, a dry well or a downspout run, order Drain Rock or #57 Limestone. Both are washed and clean, so water moves through instead of sitting in fines.
For a dry creek bed or heavier decorative work, Large River Rock is the rounded option. RipRap is the angular stone for bank and slope armoring, culvert outlets and ditch checks.
For a garden path or a side yard, Walkway Gravel gives a finer, walkable surface than a drive takes. Shredded Mulch covers beds and tree rings and holds moisture through a summer.
Ground Conditions Across Carroll County
Across the Ozark Plateaus, the soil is cherty, acid clay loam over limestone and dolostone. Chert gravel runs right through the profile, and rock or rubble sits close to the surface on side slopes.
This is karst country. Sinkholes, springs, losing streams and caves sit under the plateau tops, so water leaves through the rock rather than running across it.
That cuts both ways for a base. Runoff drops underground fast through fractured limestone, but the residual clay filling the joints holds water at the surface after a long rain.
A base built over ground like that needs the fines-bearing material that compacts, which is why SB-2 base is the starting point for a drive or a pad. Clean washed stone belongs in a drainage layer, not under a slab.
Erosion is the other driver. Steep hollow slopes and flashy Ozark streams scour drive shoulders, culvert outlets and creek banks when heavy spring rain hits.
RipRap armors those spots where a rounded stone will not hold. Base, drive and patio work runs almost all year here, with winter cold snaps and a wet spring the interruptions.
The late-summer dry spell is the easiest time to get real compaction. Freezes come in runs from December into February, and shallow freeze-thaw lifts loose gravel and heaves unbound surfaces before spring.
No statewide frost depth figure is published. The Arkansas residential code has each jurisdiction set the frost line and requires exterior footings at least 12 inches below undisturbed ground, so confirm the local figure before footings go in.

Choosing the Right Material
Benton County sits on the same Ozark Plateaus ground as Carroll County, cherty clay loam over limestone and dolostone with karst underneath. The base and drainage choice there is the same as here.
Madison County spans more than one ground region, taking in both the Boston Mountains and the Ozark Plateaus. Where the ground shifts to Boston Mountains, the profile changes and the base decision follows it.
Newton County is Boston Mountains ground: stony, acid silt loam and clay over flat-lying sandstone and shale. Rock benches, ledges and loose colluvium sit on the steep slopes.
Ridge soils there are thin, and only the foot of a slope carries any depth. Thin ground over sandstone changes what a base course can do, and loose colluvium on a slope is where rip rap earns its place.
