Weight. The weight (tonnage) of a pile is determined by multiplying the volume by the density. CalRecycle’s Solid Waste Cleanup Program has developed approximate pounds per cubic yard (lbs/cu yd) estimates for various materials. The actual density depends on the homogeneous nature (uniformity) of the pile in both void space and material type.
Nov 05, 2020· Use this formula to determine how much crushed stone you will need for your project: (L'xW'xH') / 27 = cubic yards of crushed stone needed In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27.

How Density Of Crushed Granite Stone Density 6 X 9. Stone crushed weighs 1602 gram per cubic centimeter or 1 602 kilogram per cubic meter ie density of stone crushed is equal to 1 602 kgm In Imperial or US customary measurement system the density is equal to 100 pound per cubic foot lbft or 0926 ounce per cubic inch ozinch.
Density of coarse Aggregate. Following are the density of coarse aggregate. Broken stone ballast. Dry well shaken=1600—1870 kg/cum. Perfectly wet =1920—2240 kg/cum. Shingles 3-38mm=1460 kg/cum. Gravel. Loose = 1600 kg/ cum. Un disturbed =1920-2160 kg/cum.
For example, if this figure is 3″ multiply by .25 for this measurement in the formula, since three inches is a quarter of one foot. Sometimes crushed stone is sold by the ton. To figure out the how many tons you will need is not hard to do. You will have to know that the standard weight contractors use for crushed stone is 2700 pounds per

Jun 09, 2005· My many years estimating on the contractor's side give me confidence using a factor of about 150 lbs/cu ft (or about 2.03 tons per cubic yard) -- this is higher than a soil engineer will tell you (that is, a this same aggregate soil lab compaction at proctor may be about 128-130 pcf dry density; and 138-145 pcf wet density).
Mar 09, 2021· Use a nuclear density unit. Everytime you use it you calibrate it against a block of granite and adjust your calculations accordingly. ️🤡 By dropping angular competent crushed stone with no compaction you will be able to obtain around a 90% compa
Smaller rocks can be placed on a scale to find their weight easily. Larger rocks, however, either cannot be moved without heavy machinery or will break a normal scale. In this case, it is best to measure the dimensions of the rock and calculate the weight using the rock…

Apr 26, 2017· Bulking factor is a ratio comparing the volume of a quantity of moist granular material to the volume of the same quantity when dry. There are many ways of classifying the soil in terms of it's ease of excavation including seismic techniques. The most common in the United Kingdom at present however is the Ease of Digging scale…
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 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%.

Formula of volume: length x width x depth. Answer = 10 x 10 x 1 = 100 ft 3. Please note that all measurements should be in same units. Finally to calculate the weight of gravel required, multiply the volume with the density of the material. Let’s assume that the density of the material is 47.5723 kg/ft3.
Calculate the volume of the space to be filled. For example, find the cubic footage volume of a backfill area that is 8 feet wide, 6 feet deep and 50 feet long. The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of …
