## how much crushed stone do you need? a sure-fire formula

So you are planning this great DIY project for the summer that will spruce up your yard considerably. You are quite excited, but there is just one problem: It requires crushed stone, and you have no clue how to calculate how much you will need.Crushed stone is a material that is typically used as a base or underlayment, upon which the stuff that actually shows -- for example, the concrete of a patio -- will rest. Guessing is rarely a good solution to such dilemmas when undertaking a big project, so let's look ata (relatively) simple way to figure out the correct amount.

The word, "relatively" is used because a formula is involved. And many of us, as soon as we hear the word, "formula," start quivering with fear. "What, math? Hey, I didn't sign up for this. I just want to do a DIY project. What sadist decided to make math part of it?" This is understandable, so some reassurance is called for. When the formula is actually provided for you (as opposed to your having to think up the formula, yourself), it is really pretty easy to use. All you have to do is plug in some numbers. So take a deep breath and let's get started:

In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by theheight (H), in feet,and divide by 27. This will tell you how many cubic yards of crushed stone you need.

As an example, let's say your DIY project is a patio, and it calls for the use of crushed stone as a base. If your patio is 20 feet long and 10 feet wide, and you need6 inches of crushed stone for the base, you would plug those numbers into formula, like this:

If your number comes out as a fraction -- and it probably will -- round up. In the example above, you would round the 3.7 cubic yards of crushed stone to 4 cubic yards of crushed stone. It is better to have a little extra than to run short.

Crushed stone is produced by passing stones through a crushing machine at a quarry. Various types of stone are used in this operation, such asgranite and limestone. At the bottom of the crushing machine lies a screen that traps the the crushed stone product (the finer material that passes through the screen is also kept and sold -- as stone dust).

Above, mention was made of using crush stone as a base for various DIY projects, such as those that would involve pouring a concrete slab. But this material has a wide range of applications in the landscape. While it often serves as a base for something else (in which cases no one actually sees it once the project is complete), this is not always the case.

## crushed fines | acme sand & gravel

Crushed Fines and also known as Quarry Dust, is a form offractured gravel chipsand fine dust used to solidify the base under patios and walkways. The Sub-Base is laid above the ABC or Sub-Grade at 1 to 2 inches on light weight traffic areas like pathways and paver patios.

## how many yards is a ton of crusher run?

Likewise, how much does a ton of crusher run cost? Crush & Run Cost per cubic yard is about \$20 and per ton about \$28. This material-also known as crusher run, quarry process, dense grade aggregate or road stone-is the combination of crushed rock and dust created in the process.

To measure the driveway in cubic feet, multiply the length by width by depth. For cubic yards, divide the total cubic feet by 27. Because one cubic yard of gravel is equal to 1.13 tons, you can multiply your total cubic yards by 1.13 to convert this measurement to tons.
