What is the Best Size of Gravel for a Driveway?

Which Gravel to Use for Your Driveway?
The type of gravel that you need to use for your driveway depends on what you prefer as well as what best suits your area. There are three common sizes of gravel used in driveway installation. For the first layer, choose gravel that is as big as baseball size rocks. These are referred to as the #3 gravel which provides a good foundation and drainage for your driveway. Moreover, the size of gravel prevents smaller rocks from disappearing into the soil.
Different Sizes of Driveway Gravel to Choose From
There are different sizes of gravel that you can choose from for your driveway which includes base gravel #3, item #4, crushed stone #57, crushed stone # 411, and pea gravel. Let us learn more about the different gravel sizes below.
Base Gravel #3
Bear in mind that gravel is graded by size. Usually, three different sizes of gravel are used in driveways. The gravel is placed in layers to provide a solid foundation and also to make sure that there is proper drainage. For the bottom layer, #3 gravel is a common choice. This size of gravel is made from machine-crushed stone and rock fragments.
Another gravel size that you can have for your driveway is item #4. This gravel is made up of sand, dirt, and machine-crushed stones that measure about the size of a golf ball. Furthermore, item #4 is available in various compositions. For instance, one composition is made up of recycled brick, concrete, rock, and other stones. Regardless of what it is made of, this size of gravel is ideal as a base layer for driveways.
Crushed Stone #57
This size of gravel is usually used for the middle layer of the driveway. Crushed stone #57 is made from golf-ball-size crushed stone. Aside from driveways, this machine-crushed stone is a good choice when it comes to landscaping. The size of the gravel provides proper drainage.
Crushed Stone #411
For the final layer of the gravel driveway, you can use crushed stone #411. It is made up of smaller gravel that is mixed with coarse rock dust called fines. The mixture of small stones and rock dust helps form a stable and solid surface that can withstand heavy traffic and vehicles.
This size of gravel is an attractive option that you can use for the top layer. It is made up of smooth, small, and rounded weathered stones. Furthermore, this type of gravel is available in many colors. It is a popular choice for gravel driveways because it provides an attractive finish and smooth texture. On the other hand, the downside to this gravel is that the rounded stones do not lock together so they will move when a vehicle runs over them. As a solution, you can have an edging added to the driveway so that the material holds in place.

Gravel sizes for this layer usually contain rock dust that helps the pieces of gravel to adhere firmly to each other.
