What is SB-2 base and what is it used for in Logan County?

SB-2 base is a dense-graded 1 1/2 inch minus crushed stone with the fines left in, so it binds and compacts under a roller. In Logan County it goes under driveways, parking pads, shed and building pads and pipe bedding. Cities and counties write the same material into their street, sidewalk and parking standards as Class 7 base.

How deep should a gravel driveway base be in Logan County?

Depth depends on your subgrade. The valley ground here is deep silt loam and clay that lets go of water slowly, and a high water table sits under the flat bottomland near the river. Wet clay softens and pumps under traffic all winter, so the base has to carry the load above it. No single depth fits every site.

How much gravel do I need for my project?

Quantities are ordered by the ton or by the yard, and each product page has a calculator. Size the load there before you order, then pick your delivery date at checkout. If your ground is soft or the area is irregular, those are the details to settle before you commit to a figure.

Logan County SB-2 Base and Gravel Delivery, AR

Arkansas Rock Supply brings gravel, stone and aggregate delivery in Logan County, AR to your job. The ground here decides how a base performs, and the Arkansas River Valley runs on SB-2 base.

SB-2 is the dense-graded 1 1/2 inch minus crushed stone with the fines left in, so it locks up under a roller. On the deep silt loam and clay of the river bottoms and terraces, that locking quality matters more than anything else.

Materials Delivered in Logan County

SB-2 base is the standard Arkansas base material, and it is what most drives, parking pads, shed pads and pipe bedding start from. Engineers and city standards write the same material as Class 7 base.

That table sets the aggregate base course gradings as Class 1 through Class 8, with Class 7 the 1 1/2 inch dense grading and Class 8 the 1 inch version. Section 302 covers select material used as a foundation course underneath.

Treat these as how material is specified in Arkansas, not as a certification.

Above the base, washed stone does the drainage work. #57 Limestone goes into French drains, foundation and pipe drainage, and concrete aggregate, while 3/4" Crushed Stone covers drainage beds, construction entrances and drive surfacing where no fines are wanted.

For a tighter surface, Screenings bed pavers, flagstone and brick, fill joints and leave a firm walking surface. Washed Sand beds and levels under slabs and pools, and Mason Sand handles brick, block and stone work.

Decorative work leans on river material. Arkansas River Rock fills beds, borders and dry creek beds, while Large River Rock suits heavier decorative work and light bank protection.

Top Soil and Fill Dirt handle lawns, grading and raising low ground.

Ground Conditions Across Logan County

Work runs nearly all year in the Arkansas River Valley. A wet late winter and spring is the real limit, and summer heat can dry a surface before it can be rolled.

The valley ground is deep silt loam and clay on the river bottoms and terraces, with shale and sandstone uplands between them. Clay subsoils let go of water slowly, and flat bottomland holds a high water table near the river.

That slow-draining clay is the reason a base needs real depth and a drainage layer. Water that cannot leave the subgrade softens it, and a thin base over wet clay will not hold up under traffic.

Backwater after heavy rain upstream, plus bank scour and flood flow along the Arkansas River and its lakes, drives erosion here. Sheet erosion off bare valley clay in spring thunderstorms takes the same toll on exposed ground.

Mild winters bring short hard freezes and the occasional ice storm, so frost action is shallow. No statewide frost figure is published, and each Arkansas jurisdiction sets its own frost line.

Wet clay softens and pumps all winter, which damages a base more than cold does.

Delivery Across Logan County

Order online and a dump truck tips your load on site, in one pile, in Booneville, Paris, Magazine, Subiaco, New Blaine, Scranton, Ratcliff or Delaware. You size the load by the ton or by the yard, and each product page has a calculator.

Pick your delivery date at checkout and the truck arrives with the material. A bulk delivery is one tipped pile, so plan where you want it left before the truck reaches the property.

Timing follows the season. Book ahead of a wet spring spell so a soft, saturated clay subgrade does not decide the schedule for you.

Choosing the Right Material

Logan County sits in the Arkansas River Valley, on the same deep silt loam and clay bottoms and terraces, with shale and sandstone uplands between the flat-topped mountains. Sebastian County sits on the same valley ground, so the base and drainage choice does not change between them.

Scott County is different. Its ground is stony, gravelly loam over folded and faulted sandstone, shale, chert and novaculite, with rock fragments through the profile.

Soils are shallow on the long ridges and deeper in the valleys.

That changes what a base sits on. Rock fragments and shallow ground drain faster than valley clay, so water leaves a base there more readily and the drainage layer carries less of the load.

In Logan County the clay holds water, so a clean washed stone under and beside the base matters more. Pope County spans the Arkansas River Valley and the Boston Mountains, so its ground changes with the elevation.
