Rock weight varies by gravel pit location, but on average 1 inch rock has a proctor (weight per cubic foot) of about 130 lbs. .33 cubic yards is 9 cubic feet, so you are about 1,170 lbs. Again, that could be plus or minus 100 lbs based on the aggregate source.
Jul 20, 2020· Calculating Crushed Stone by Weight. A final calculation is if you need to figure out the weight in tons of your crushed stone. You might not need to figure this out, but it's handy to know. Most gravel weighs about 1.5 tons per cubic yard. So, for the examples above, 2.45 cubic yards of gravel weighs 3.68 tons or 7,350 pounds.
Jun 09, 2005· Several sources state that "most natural" aggregates have particle densities between 150 and 181 (lb/ft^3). In the Civil Engineering Reference Manual (CERM), under chapter 48, "Properties of Concrete and Reinforcing Steel" Pg. 48-2, "Aggregate" states that, "Most sand and rock aggregate has a specific weight of approximately 165 (lb/ft^3).
Gravel (crushed stone) will vary in compactness from 1.6 to 2.2 tons per cubic meter. The size of the pieces will change the weight per cubic measure. One cubic meter equals 1.3 cubic yards; and a metric ton is 2200 pounds (1,000 kilograms); and...
May 20, 2019· crushed rock permeability. Second, the case study presents an example where mass limited analytical measurements can be obtained, and mathematical algorithms adjusted to report accurate crushed rock permeability with samples that are approximately less than 30-50 grams in weight.
Sold by the cubic yard, 5/8" Minus Crushed Concrete is almost exactly the same as 5/8" Minus Crushed Rock both in how it looks and its applications. It is used as a top course for driveways, walkways, and compacts down (+ great for potholes too). The best part is that it is usually $3-5 cheaper per yard than 5/8" Minus Crushed Rock.
So, in this situation, you would multiply .33 x 80, which totals 26.4 cubic feet. You will need enough crusher run for 26.4 cubic feet to complete the project. When you buy crusher run by the ton, you will need to determine how much rock to buy. The standard weight that is used by contractors for crushed stone is 2,700 pounds per cubic yard.
a) Water content = 186 Kg/cum b) Sand as percentage of total aggregate by absolute volume = 35 %. Thus, Net water content = 180.42 Kg/cum Net sand percentage = 33 %. 6. DETERMINATION OF CEMENT CONTENT W/c ratio = 0.5 Water content = 180.42 Kg/cum Thus, Cement content = 360.84 Kg/cum Adequate for moderate exposure Say 360 Kg/cum. 7.

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 cubic yard. Multiply the number of cubic yards by 2700 and divide by 2000. This value is the number of tons that you will need.

Gravel is a naturally occurring material, consisting of water-born pieces of rock and is found in buried or current stream beds. The peas are usually rounded with smooth surfaces, while other properties depend on "parent rock". You may also encounter "crushed gravel", which is simply larger gravel particles crushed to a smaller desired size.
Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.

Standard density for asphalt is 145 lb/ft 3 (2322 kg/m 3). Multiply the volume by the density (in the same units) to get the weight The measurements are not always precise and there might be waste during the application process, so you should consider purchasing 5-6% more asphalt than estimated so you don't run just short of what you actually need.
