SB-2 base is the Arkansas name for the dense-graded 1 1/2 inch minus crushed stone that locks up under a roller. It goes under drives, parking pads, shed and building pads and pipe bedding.
Materials Delivered in Perry County
SB-2 base is the standard base material in this state. It is a dense-graded 1 1/2 inch minus crushed stone with the fines left in, so it binds and compacts instead of staying loose.
When a city or county street, sidewalk or parking standard calls out a base course, it is usually written as Class 7 base, which is the same material under the name engineers use.
Section 302 covers select material used as a foundation course underneath.
Use the Class 7 name when you are working to a written spec.
Around those, the yard carries driveway gravel for surfacing an existing drive or topping a compacted base, and walkway gravel for paths and side yards that need a finer surface than a drive. Washed sand beds and levels under slabs and pools, and mason sand goes into brick, block and stone work and paver joints.
Fill dirt raises low ground and builds a pad up out of the wet before a base course goes on.
Choosing the Right Material
Perry County spans two ground regions. Perryville and Casa sit in the Ouachita Mountains, on stony, gravelly loam over folded sandstone, shale, chert and novaculite.
Conway County and Yell County both reach into the Arkansas River Valley, the same deep silt loam and clay over shale and sandstone uplands. On that ground the base and drainage choices are the same ones you would make on the valley side of Perry County.
On the valley clay, a fines-bearing base like SB-2 base is what you want under a drive or pad, because it compacts into a firm layer.
On the mountain ground, where rock sits close to the surface, drainage is the bigger question, and a washed stone such as #57 limestone or drain rock carries water away instead of holding it.
Ground Conditions Across Perry County
In the Ouachita Mountains, tilted shale and chert beds shed water off the ridges quickly and funnel it into narrow valleys. A drive or pad there takes concentrated flow arriving from above rather than the rain that lands on it.
Fast ridge runoff and steep drive cuts strip surfacing after a big storm.
In the Arkansas River Valley, flat bottomland sits over a high water table near the river, and clay subsoils let go of water slowly. Backwater from the Arkansas River and Lake Dardanelle follows heavy rain upstream.
Bank scour and flood flow work on the river and lake edges, and spring thunderstorms sheet erode bare valley clay.
That is where a thin base shows its weakness first. A fines-bearing base that stays wet under traffic softens and pumps, and the surface above it breaks up.
Work runs nearly all year in both zones. In the mountains, winter ice and a wet spring are the limits, and rocky ground that has drained compacts well and holds.
In the valley, a wet late winter and spring is the real limit, and summer heat can dry a surface before it can be rolled.
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.
In the mountains, north-facing slopes hold frost longest and thaw wet, which is when a gravel drive ruts most easily.
