Selecting a locally-quarried crushed limestone gravel supports a local business, lowers transportation costs and results in a hard yet water-permeable surface on your new driveway.
Things You Will Need
-
Contact the local building department to determine whether a permit is required to build a gravel driveway.
-
Measure the planned driveway space. The average two-car driveway is 20-by-20 feet, or 400 square feet. Determine if any grading or culverts are necessary for water runoff. For example, when building a driveway on the side of a hill, a ditch is needed on the high side to prevent runoff from undermining or eroding the gravel.
-
Remove all topsoil from a 21-by-21-foot square and to a depth of 10 inches. Rake smooth, then run the plate compacter over the soil.
-
Install the landscape timbers on each side of the driveway. Drill holes at each end and the center, then pound rebar through the timbers and into the ground.
-
Pour 4 inches of no. 3, or 2-to-3-inch size crushed gravel into the driveway pad. Rake evenly over the driveway space, mounding slightly down the center, then compact with the plate compactor. Sprinkle with water and compact again.
-
Add 4 inches of no. 57 or 3/4-to-1-inch size crushed gravel. Rake evenly over the gravel base. Sprinkle lightly with water and compact firmly.
-
Pour 4 to 6 inches of no. 21-A, or 3/8-to-3/4-inch size crushed limestone gravel. Again sprinkle with water and compact firmly.
