Picture sand stockpile calculator
It is a great driveway base material, bike path base fill, paver patio sub base, walkways, and just general fill material. It is also used as a road base, and in some locations it is used for paving roads, for example Russia has over 400,000 km (250,000 mi) of gravel roads.
Ĭrushed stone is often used as a material for producing concrete. If it is mixed with sand the density is around 1920 kg/m3 or 120 lbs/ft3.
Typical gravel density (dry) is between 15 kg/m3 (95 to 105 lbs/ft3). Note that a gravel's density depends on this, so make sure to consult the manufacturer's technical specifications for the estimated density which you should then input in our gravel calculator. This means that no side of any particle will be larger than the specified measurement, which is achieved through screening, usually using industrial automated screeners. Gravel is usually sold with a guaranteed maximum particle size, e.g. You may also encounter "crushed gravel", which is simply larger gravel particles crushed to a smaller desired size. The peas are usually rounded with smooth surfaces, while other properties depend on "parent rock". Gravel is a naturally occurring material, consisting of water-born pieces of rock and is found in buried or current stream beds. In case you end up with a large number of sections to sum, you might appreciate our summation calculator. The one-click copy function of our tool should come in handy. In case the area you are calculating has an irregular shape, things get a bit more difficult, but in general what you would want to do is divide it in several regularly-shaped sections, calculate their volume and gravel requirements and then sum them up together. Again, the gravel calculator will do this math for you. To calculate the foundation area the calculator needs its diameter, since the formula is π x r 2, where r is the radius, or diameter/2. The volume of a figure with a round foundation is its height times the area of its foundation. If the area you want to cover with gravel, or the shape you want to fill is round, the calculation is a bit different: Our pea gravel calculator handles all this for you given you supply the dimensions. The volume formula for a rectangular (or square) box in cubic feet is height(ft) x width(ft) x length(ft), as seen in the figure below:įor example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft, you need to multiply 1ft x 3ft x 6ft = 24ft 3 (cubic feet) of gravel, then multiply that by the density. To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. It is often a good idea to consider buying 5-6% more gravel than estimated by our calculator, to be on the safe side.
