Edge cracking happens because of a lack of support at the pavement edge and, because rural roads and driveways tend to be narrow, traffic is forced to drive close to these outer edges. Poor drainage, poor quality base/sub-base, and asphalt shrinkage can also contribute to the formation of edge cracks.
