If you have a gravel driveway in Nashville, TN, chances are your gravel isn’t really gravel. It’s crushed stone. Ever heard of it?
Crushed stone is a unique product that is perfect for paving with because of its rough, angular cut. The gravel you picture in your mind might look like crushed stone — but this image isn’t totally accurate. How so? Let’s take a look.
So what is crushed stone?
Crushed stone is basically differentiated from gravel in that it is man-made, in a sense. Crushed stone is just stone that has been crushed from a larger rock. Because of this, crushed stone is sharp and angular in shape. This helpful post points out that crushed stone is mainly a construction aggregate, meaning it is largely used by big commercial companies in things like paving and concrete mixing. It is created by harvesting a rock formation — usually limestone in the Nashville area — and then crushing that large rock up in a machine called a crusher. And even though crushed stone is largely commercial, you can still find it at your local Nashville, TN natural stone dealer because it is useful in filling in driveways and drainage ditches, just like gravel is.
If gravel is different, what is it?
Speaking of gravel, what’s the big difference between it and crushed stone? It’s really quite simple: gravel is not man-created. It is rounded in shape and texture and is made by nature. This definition reveals that gravel is actually a common geological formation. The weathering and erosion of bigger rock formations leads to the development of smaller rocks breaking off. Gravel is easily harvested by rock quarries and Nashville, TN natural stone dealers alike because of the large piles of it that are created by natural forces.
Uses for Crushed Stone vs. Gravel
Now that we see more clearly how crushed stone compares to gravel, you’re probably wondering what you can do with each. Well, it essentially boils down to preference and use. For example, if you’re filling in your driveway, what kind of texture do you want it to have?
The sharper angular rocks of crushed stone may actually create better friction for gripping tires, but pea gravel is pretty and softer to walk on. Crushed stone is also obviously more useful for commercial projects, as you can see on this extensive list of uses for crushed stone. Crushed stone is useful for lining drainage ditches, paving driveways, as an aggregate for concrete and asphalt, and many more things. Whereas the tiny, rounded brown pebbles of pea gravel, for example, are useful as aquarium lining, in landscaping as mulch, and as a playground covering. So are other gravels (quartzite, screened stone, washed stone, and so on) — mainly because of their rounded texture and natural appearance. As you can see, we have lots of options for both crushed stone and gravel for our Nashville homes.
