best gravel for your driveway - 9 top options - bob vila

When you think of a gravel driveway, you may imagine a sleepy, dusty lane that leads to a quaint rural cottage or farmhouse on a lonely country road. In reality, gravel is equally at home in rural, suburban, or urban environments, and its durability, affordability, and ease of installation make it a smart paving option for driveways. If you are considering a gravel driveway, you should be aware that not all gravel is created equal: Gravel can range in size from tiny sand-like grains of crushed stone to larger rocks left behind by retreating glaciers. Gravel can be made from just about any natural stone and is available in a wide variety of colors. A gravel driveway requires at least three layers, beginning with large stones at the bottom, medium in the middle, and small stones on top. Check our guide to see which types of stone are best for the job

Gravel is typically graded by size, and most driveways use at least three different sizes of gravel that are put down in layers to create a solid foundation and ensure proper drainage. A popular choice for the bottom layer is #3 stone, which ranges in size from one to two inches in diameter. Also called “clean stone,” this base gravel is made from machine-crushed stone and is composed of irregular rock fragments. A four-inch-thick layer of this type of gravel forms a strong foundation for the driveway while ensuring proper drainage

Another popular gravel often used as a foundation for driveways is known as Item #4, which is a mixture of machine-crushed stones that measure roughly the size of a golf ball, along with sand and dirt. Item #4 comes in a variety of compositions, including Recycled Item #4, which consists of recycled concrete, blacktop, brick, rock, and other stones; Quarry Item #4, or crushed limestone; Gray Item #4, which is dark gray in appearance; and Crushed Bluestone Item #4, a dark blue-gray stone often used in municipal paving projects. No matter its makeup, all Item #4 gravel is suitable for the base layer of a driveway

The middle layer of a gravel driveway is typically constructed of golf-ball-size crushed stone, or #57 stone. This type of gravel, made from machine-crushed stone, is also a popular choice for landscape design and for constructing French drains, as the size and shape of the rock fragments promotes proper drainage and prevents the gravel from locking together to form an impervious surface.

The final layer of a gravel driveway consists of smaller gravel blended with coarse rock dust, known as “fines.” Crushed stone #411, which is a mixture of #57 stone and coarse rock dust, is a good option for this top layer. This blend of small stones and rock dust will fit tightly together as the stones settle, forming a stable, solid surface that can stand up to heavy vehicles

Quarry process stone—also known as crusher run—is another good option for the top level of a driveway or walkway. Composed of a blend of smaller crushed stone and stone dust, crusher run typically includes a higher percentage of stone dust fines. As the gravel settles, the dust seeps into the spaces between the gravel and compacts, forming a smooth, semisolid surface. If you use quarry process stone in your project, it is essential to crown the driveway—grade it so that the middle is slightly higher than the sides—to ensure that rainwater will drain properly and also to reduce damage to the driveway
