Maintenance
The crushed gravel driveway surface is constantly in need of maintenance, from raking the stone periodically, to spraying for weeds (or pulling them by hand.) Every 4-6 years the driveway may have to be topped with new gravel. When doing so always maintain a crown so water will drain away from the driveway.

Crushed stone driveways. Gravel driveways.

A single lane driveway is usually around 10 feet (3 m) wide and, where possible, with an apron of approximately 15 feet (4.5 m) wide. A wider and flared apron makes it easier for cars entering or leaving. The apron is the driveway section between the sidewalk and the street. A circular driveway has two aprons. For aesthetic reasons the apron can be made of a different material than the main driveway. Adding drive way edging can also drastically change the overall appearance of your driveway.
Crushed gravel driveways are usually a mixture of sand, silt, clay and larger aggregates (pebbles and small stones). These driveways are still a pretty common sight out in the country but not in the cities where virtually all driveways are paved.
New installations. After excavation is completed the subsoil should be compacted to avoid the driveway from "drifting". After the crushed stone has been added it should be compacted as well. To add some colour to the driveway it can be finished off with a layer of crushed red bricks.
Advantages. Relatively easy to install for a d.i.y person. Low cost compared to any other type of driveway finishing.
As a rule, very little damage due to frost/thaw cycles in northern climates.

Disadvantages. Controlling weeds and grass could be quite a challenge. Shoe removal on entering the house is a must as crushed stone driveways are "dirty". Snow removal, either by shoveling, ploughing or using a snowblower may be a challenge. The driveway has to be cleaned a few inches above the surface to prevent the gravel from being pushed onto the lawn or gravel from becoming airborne if a snowblower is being used.
