Crushed limestone is a great choice for a material to build a permanent driveway for a new home, or for renovating the current driveway. The crushed limestone is a material that is easy to work with, can be crushed to specific dimensions, and dyed for a wide variety of colors. While building a new driveway is not something that is normally done as routine home maintenance, this project is well within the parameters of a do it yourselfer's skill set. With some rented equipment, a couple tons of crushed limestone, and plenty of time, you can construct your own crushed limestone driveway and save a lot of money.

Step 1 - Plan for Everything

When working on a driveway you are essentially building a road. To do that you need to have a lot of different material and equipment at the time of working on the driveway. The first step is to plan out the driveway itself. Where it is going and what it will look like are the 2 most important aspects. Use graph paper to draw out the driveway and try to get it as close to scale as possible.

Another part of the planning process is lining up the required equipment beforehand to be available at the same time. This means having the gravel and crushed limestone delivered, renting the power equipment, and even lining up help from friends.

Step 2 - Prepare Land

One of the biggest rules of building a driveway is to not build it on top of the topsoil. You must remove the soil and build a strong base for the crushed limestone driveway. Outline the shape of the driveway with the landscape paint and mark off the area with stakes and the string.

Using the Bobcat with a loader bucket, remove the soil down to 8 to 10 inches, depending on where you live. The farther north, the deeper you need to dig. As you are digging, keep in mind drainage of water. Have the driveway slope away from any buildings so that the water will run away instead of causing potential flooding in basements.

Step 3 - Install Drain Pipes

Once the soil has been removed, and the surface leveled off, spread out the black plastic vapor barrier. Make sure that is covers the entire ground area. Lay down the black plastic drain pipes on the bottom of the area that you just dug out. They should run the length of the driveway and spaced at 6 foot intervals.

Step 4 - Spread out Gravel Base

With the Bobcat, spread out the gravel base over the entire surface area of the driveway. It should be at least 6 inches deep and cover the plastic pipe. Once it is spread out evenly, use the compactor to pack it tight.

Step 5 - Spread Crushed Limestone

Begin to carefully spread out the crushed limestone onto the driveway. Use a tractor with a rake attachment and smooth out the limestone to a level surface. Compact the limestone, but not as tight as the gravel.
