The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to 100% of some form of "proctor density", because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%.
Apr 29, 2003· I have a question about 3/4" crushed stone. I read several places that 3/4" crushed stone is "self-compacting". That is, you dump it in a trech (as in under a concrete footing or floor) and you don't have to compact it with a plate compactor it is already as "compacted" as it needs to be.
Oct 04, 2011· No. 57 stone is an easily consolidated material but it is not self-consolidating. Uncompacted or dumper deposits of No. 57 stone can settle about 1″ per foot of thickness. No. 57 stone should be placed in lifts and consolidated using conventional compaction techniques.
Each type of crushed stone will settle at a different rate and will have a different compaction rate. As a result, various materials will need to be compacted down more heavily than others. Depending on the specific project, you may end up requiring 1/2″-1 1/2″ of extra material in order to achieve the desired overall depth post stone
Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure
advice on compacting crushed stone barn floor--am I totally hosed? Aug. 10, 2013, 07:11 PM. So we finally got around to compacting the stone floor that we've put in the old barn. I know it's better to compact as you go (put a few inches down, compact, add
were graded crushed stone, it was decided that only the vibrating roller would be used. The following routine procedure was established for the installation of the test sec tions. Test rolling was begun as soon as possible after the material had been spread and "knocked down" by the contractor. In most cases, little or no compactive effort
Oct 22, 2011· The engineer confirmed 95% compaction for placed 3/4 stone. This will not be satisfactory in this particular case. The engineer says he may have to use granular A and compact every foot. Sounds like this is what he'll be doing because he needs 100% compaction.

Crushed stone is a versatile material and can also be used for many commercial, residential and DIY projects. Due to its modest cost and easy installation, it is often used for horse riding arenas (screenings) and walking and bike paths (screenings and 3/8” size), as well as for drainage systems and as a base or sub-base for residential

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, & 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.
Compacted gravel is used to provide a level base for walking on or for laying stone pavers. Compacting gravel can be a labor-intensive process and can be costly if you hire a professional to do. However, with the right tools and directions, you can lay the compacted gravel yourself, saving hundreds of dollars.
Jan 06, 2005· I have not seen a procter for crushed stone. Typically the stone is placed in 12-18" lifts and tamped once or twice. The stone is so much stronger than the soil and is unaffected by moisture content that lab or insitu density testing is not done. We use it in freezing weather to backfill when soil would be impossible.
Crushed Aggregate Base Coarse (Compaction Gravel) shall consist of one or more courses or layers of coarse aggregate, either crushed gravel or crushed stone, fine aggregate and binder or filler blended as necessary to produce an intimate mixture of the required gradation and stability.
Section 301 Base, Subbase, and Subgrade Aggregate Crushed stone Crushed angular particles of quarried rock retained on a No. 10 sieve. Use specialized pneumatic or vibratory compaction equipment or a combination of both types of machines. Do not use tamping rollers. Use pneumatic compaction equipment conforming to 207.3.6.2.
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers.It is distinct from gravel which is produced by natural processes of weathering and erosion, and typically has
Sep 20, 2007· “Six inches of well-graded gravel or crushed stone material properly compacted will give good results,” said Mark Conrardy, a sales engineer manager for Wacker Corp., Menomonee Falls, Wis. When properly compacted, both native soils or imported granular materials can provide good support.
Apr 26, 2011· When compacting soil, you do it in 6" lifts. What about compacting washed gravel or crushed rock? I was told that # 57 gravel is self compacting. I find this hard to believe. I want to be dang sure. What do you do? What has been your experience. Anyone here have the answer. Thanks The situation is filling a 3' wide x 7' deep ditch that will have concrete paving over it.

Similar to an urban myth, the words ‘self-compacting’ soils have unfortunately taken on an aura of acceptability. 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.
Compactor Procedure. The aggregates tested were a granite-gneiss, a crushed gravel, a dolomitic limestone, and a basalt. A prototype field compaction 'testing program was conducted using the same four aggregates. The materials were compacted under simulated field conditions over two different subgrades in test pits located at Clemson University.
Self compacting stone. What type of stone would be best for filling this cavity that is a planned two-car garage addition? It is approximately 7 feet deep. can't get the same result using the recycled concrete because there's too much friction between the sand and angular crushed stones in the recycled mix. The recycled concrete does
Nov 18, 2008· I'm laying a shed foundation of 3/4" crushed stone. Due to levelling issues, I'll be putting down around 12" depth of it (about 7 yards total crushed stone in a 144 sq. foot area). Question: -If I rent a jumping jack for the weekend (around $91), am I ok putting ALL the crushed stone down and THEN compacting it w/ the jumping jack all at once?
Martin hit the nail on the head. Engineers feel all warm and cuddly about 3/4" crushed stone with fines because they can get a standard proctor of material density and compaction. However, 3/4" crushed will pass very little water. We use 3/4" clean stone under footings all the time. As long as it's a
Compaction shall not occur if the moisture content of the aggregate is greater than 6.0%. The maximum allowable deflection will be . 100% crushed stone or ACBF. CONSTRUCTION REQUIREMENTS 302.03 Preparation of Subgrade Subgrade shall be prepared in accordance with 207.
These binders, combined with water and then compacted with a vibratory roller or plate compactor should produce a solid, compacted surface that resists significant deformation from hiking boots and mountain bike tires. We frequently see baby strollers and road bikes using our crushed stone trails.
