Crushed stone is a good material for these types of projects and comes in many colors, textures, and sizes. But the dilemma is determining the amount of material you need. Learn a relatively simple formula so you can calculate how much crushed stone or gravel you need by plugging in a few numbers.

If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.) If you use a jumping jack, about 20% would be accurate.

Large rocks (often limestone) are processed in a stone crusher to make smaller pieces. Since it is artificially crushed, crushed stone usually has harder, sharper edges than gravel. Now that we have clarified that difference let's look at how gravel and crushed stone are further classified.

Using our crushed stone calculator, you can find the quantity and weight of the crushed stone or gravel that you'll need to layout or fill an area. The following article discusses what crushed stones are, their different sizes, and how we can use these crushed stones.

Find out what the experts know in a deep dive into the types of crushed stone and gravel. What are stone and gravel's specific roles in construction projects?

In the north country, we may dig out a foot of subsoil, 6 inches of packing gravel and 6 inches of stone dust. compact well. In no freeze areas, 4 inches over a stable subsoil is fine. Compacting the base is an extra step, but will pay off in a long lasting even deck.

If you know the price per unit mass/volume of the crushed material, then the calculator can also work out the total cost of the aggregate using the formula: $$Cost = Price,per,unit,mass times Weight$$. or. $$Cost = Price,per,unit,volume times …

CBR is defined as the ratio of the load required to cause a certain depth of penetration of a piston into a compacted specimen of soil at some water content and density, to the standard load required to obtain the same depth of penetration on a standard sample of crushed stone (usually limestone).

I looked at the gravel you are using. I would suspect you might see 1/2 to 3/4 inch of compaction, especially if you just laid it down. All you can do is start compaction, see what it looks like and add or rake off a bit to meet you needs.

A mixture of coarse to fine-grained particulate material used in construction, typically including sand, gravel, and crushed stone. Aggregate sieves used to separate material by size (gradation). 1⁄2 inch or 12.5mm sieve visible on right.
