The conversion for riprap varies by size but generally speaking, a conversion of 2 tons per cubic yard is sufficient. Limestone has an in situ unit weight of approximately 160 pounds per cubic foot but voids on average reduce the unit weight of riprap to closer to 150 pounds per cubic foot.
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also lbs/ (pounds per cubic foot) and if we know that a sample of ammonium nitrate has a sg of then we can calculate that its density is x = lbs/
In turn, track ballast typically rests on a layer of small crushed stones: the subballast. The subballast layer gives a solid support for the top ballast, and reduces the seepage of water from the underlying ground. Sometimes an elastic mat is placed on the layer of subballast and beneath the ballast, thereby significantly reducing vibration.
Apr 18, 2008· I'm covering a 700' sf driveway with 1/2" crushed stone approx 3 deep". volume works out to 175 cuft ( cuyd) Does any one have a quick data sourse weight to area calculation for basic matierials crushed stone / stone dust /sand/ etc.
The density and shape of Tilcon crushed trap rock meets stringent specifications for construction products. All Tilcon products are tested by dedicated quality control technicians to meet or exceed ConnDOT specifications for strength, durability and technical requirements for all construction projects.
May 05, 2011· RE: In place density of 3/4 Crushed stone TigerGuy (Geotechnical) 4 May 11 22:31 It doesn't look like there is sufficient lateral support for the rock, if the footing has a significant load.
* Average density of the material for weight calculation will be shown in the DENSITY box with g/cc as default unit. * If you know the exact density of a specific material and wish to obtain the accurate instead of average weight,
These costs vary depending on geographic location, the nature of the deposit, and the number and type of products produced. Crushed stone has one of the lowest average by weight values of all mineral commodities. The average unit price increased from US per metric ton, plant, in 1970 to US in 1990.
