You can save a bundle on a new driveway by using crushed rock instead of concrete, asphalt or other paving materials. Although concrete and asphalt are most commonly seen, especially in housing developments, crushed rock is far less expensive and faster to install. Crushed rock may be granite, limestone, concrete, or shale, and it is as easy to install as dumping and spreading it.

Crushed rock will cost about $1 per square foot for a 2-inch-thick layer. Compare this with your other options. Cobblestone and pavers will cost $6 to $13 per square. Concrete will be between $3 and $6.50 per square foot, depending on the amount of preparation required (gravel base) and whether you choose plain, colored, or concrete with aggregate exposed. Asphalt also requires a gravel base and will then run $2.00 to $7.50 per square foot.
