Remove any surface material to a depth of 6 to 10 inches.
Tamp the surface with a compactor or a tamper to make sure the ground is tightly compacted.
Lay down plastic sheeting to prevent grass and weeds from growing up through the gravel.
Rake in the first load of gravel to a depth of 2 to 4 inches, using No. 3 gravel, which is a large size gravel rock. Rake the gravel in place so the midpoint of the driveway is slightly higher than the sides so water can easily run off of the driveway.
Place another 2- to 4-inch layer of No. 57 size gravel, which is slightly smaller than No. 3 gravel and rake it into place. Check the midpoint of the driveway to keep the crown intact for drainage.
Finish the driveway with a 2- to 4-inch layer of number 21-A gravel which is very fine. Rake it into place, checking the crown for drainage.
