There are a few different methods for leveling a surface of crushed stone or gravel for a patio, whether the stone will become the surface material or a base layer for other paving materials. If the patio is small--8 or 10 feet--you can simply tape a 4-foot level to the top edge of a straight 8- or 10-foot 2 by 4 and use it to check the surface ...
Jul 08, 2020 I havent seen anything definitive on the best material for backfill. The concrete guy Ive been talking to suggested something like 2 crushed stone would be good because it is self-compacting, and its good for drainage, so I wouldnt have water sitting around by the pool walls. That made sense to me.
Aug 29, 2002 RE Compaction specs for crushed Stone Under Foundations jheidt2543 CivilEnvironmental 29 Aug 02 2111 With the 16 thickness of the stone fill, I would use a jumping jack style compactor rather than the plate compactor.
Self Compacting Stone ... cant get the same result using the recycled concrete because theres too much friction between the sand and angular crushed stones in the recycled mix. The recycled concrete does compact very well using rollers or plate compactors, but as you said, thats very tough to do in
Aug 01, 2008 Mistakes often result in poor compaction, soft surface conditions, non-accessibility, and inevitably costly repairs. Crusher fines in their purest form have no soil mixed in, they are pure crushed stone. Gravel and crusher fines differ from one another in that gravel is screened to remove the fines which contain the natural binderscements.
Nov 12, 2019 Crushed stone with stone dust in it is highly compactable and is therefore commonly used when making any kind of base for construction. Whether it is a road, driveway, building foundation, patio base, retaining wall base, or other projects needing a solid foundation, you typically find crushed stone at the bottom.
Then compact. Actually, order to cover 4 , but the only lay down half, compact that, then lay down the other half, then compact that. In other words, you dont typically order the stone to allow for compaction. You order the stone based on the volume needed prior to compaction.
Aug 29, 2002 We normally recommend a No. 57 gradation crushed stone or gravel, and a thickness of 8 to 10 inches. If thicker layers are used, we recommend that each 12-inch thickness of stone backfill be densified by making 3 or 4 passes of a walk-behind vibratory sled or plate type compactor over the stone surface. Density testing is not performed.
Apr 26, 2011 Probably self compacting 57, which is 12 to 34-inch gravel is generally considered to be self compacting. This is because there are no fines to inerfer with the movement, so it goes to where there is direct contact between the particles. Short of braking the rocks, which would require a great deal of force, the material wont get any tighter.
May 21, 2020 You cant run a nuclear densometer on washed crushed stone, so compaction documentation is visual. Larger, uniform, washed crushed stone will compact under proper effort.
You cant get the same result using the recycled concrete because theres too much friction between the sand and angular crushed stones in the recycled mix. The recycled concrete does compact very well using rollers or plate compactors, but as you said, thats very tough to do in your case.
vibrating roller. On the three graded crushed stone materials, somewhat higher densi ties were obtained with the vibrating roller, while on the fourth, a local pit material containing only about 2 percent plus No. 4 aggregate, the highest densities were ob tained with the heavy pneumatic-tired roller. In 1961 the field experiments were con
Clean gravels and crushed rock are sometimes referred to as self-compacting, meaning that if they are dumped in beside a pipe, the material will have a high density. Owners, engineers, contractors and inspectors have been known to use this expression. Some even claim that dumping in gravel and crushed rock will result in 95 percent ...
AASHTO 57 Stone Specs AASHTO 57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, amp 7 stone. This material cannot be compacted in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using 57 stone under Flexi-Pave surfaces.
Mar 21, 2016 Use your judgement to decide if the newly excavated ground can support the aggregate stone you will later apply, without the need to first compact the soil surface. It will vary by situation. Try and wait for the ground to dry if it is a little wet before compacting, but if its unavoidable, add a small amount of large gravel to help bind the ...
Crushed granite has a finer texture than gravel. Often called decomposed granite, the small pieces compact more smoothly than coarse gravel, although both materials are packed the same way.
Dec 01, 2013 A comprehensive series of drained triaxial compression tests were performed on crushed concrete aggregate CCA moist as compacted. When compared to ordinary natural well-graded gravelly soils, the peak strength and stiffness increase more significantly with dry density, while the effect of the degree of saturation during compaction is much less significant.
