Dec 07, 2004· Re: compacting gravel under a slab Tucker: With 2 to 3 feet of rock, I fail to see why you need either poly or insulation under the slab, I think I would opt for the "oozing" and the thickening effect of the "waffle" bottom, I would think that structurally it turns a 3 1/2" slab into something more like a 6 or 8" slab from a structural standpoint.

The modified effort test (see ) is sometimes referred to as the Modified Proctor Compaction Test. Soils and soilaggregate mixtures are to be regarded as natural occurring fine or coarsegrained soils, or composites or mixtures of natural soils, or mixtures of natural and processed soils or aggregates such as gravel or crushed rock.

Some even claim that dumping in gravel and crushed rock will result in 95 percent compaction meaning that the density of the dumped soil is 95 percent of the maximum density for that soil. In reality, the dumped density is only about 80 percent of the maximum density.

soil are its shear strength, its compressibility, and its permeability. Compaction of the soil generally increases its shear strength, decreases its compressibility, and decreases its permeability. SOIL CLASSIFICATIONS Considering soil compaction, the two broad classifications are cohesive soils and cohesionless, or noncohesive, soils.

Laboratory tests were undertaken on mixtures of 10%, 15%, 20%, 25%, 30%, 40%, and 50% crushed brick blended with recycled concrete aggregate or crushed rock. The research indicates that up to 25% crushed brick could be safely added to recycled concrete aggregate and crushed rock blends in pavement subbase applications.

Feb 16, 2009· If that process is followed, then the lateral pressures experienced by the wall should not be "excessive". Given that #57 crushed rock is being specified, generally only light compaction is necessary to achieve a dense backfill. In my opinion, the combination of crushed gravel and light compaction should not result in very high lateral pressures.

5/8". Minus Crushed Aggregate is commonly used on driveways and walkways. It has the fines for compaction so it will pack down and stay in place. Since it is small in size, it finishes off fairly smooth when leveled and compacted. This product is also great for base material under flagstone, retaining walls, or concrete.

It is used for footings under wood foundations, pre cast foundations, and obviously is a great water diverter. The Alaskan pipeline, and any set of railroad tracks are other good examples of crushed/washed rock as a .

Reduction in block size and rearrangement of the fill are the main factors affecting the compaction process, as recrushing and rearrangement of the broken coal and rock mass affect the secant modulus and pore size of the caving zone, causing the secant modulus to gradually increase and pore size to .

It is placed by means of attentive spreading and compacting to a minimum of 95% relative compaction, providing the stable foundation needed to support a pathway, foundation, driveway or roadway. The SubBase is a layer of small chipped aggregate and dust, typically Crushed Fines, which is laid above the ABC on driveways or heavy traffic areas.

205 EXCAVATION AND EMBANKMENT FOR HIGHWAYS. If the depth of compaction in cut sections is greater than 6 inches, excavate all material to within 6 inches of the lower limit of compaction. Plow, scarify or break up the material left in place.

Base courses of crushed rock, lime rock, and shell are compacted with vibratory, steelwheeled, or rubbertired rollers.

soils or aggregates such as gravel or crushed rock. Hereafter referred to as either soil or material. These test methods apply only to soils (materials) that have 30 % or less by mass of particles retained on the 3⁄ 4in.
