3 Types of Pavement Cracks and How to Fix Them | ACI ...
The 3 Common Pavement Cracks: Reflective. Reflective surface cracks occur when a crack or joint in the underlying pavement "reflects" upward through the surface. These types of cracks are primarily dealt with in resurfacing projects, but they can also appear in the form of "low-severity" cracks following new pavement installation.

5. Edge Cracking. As the name suggests, this is a type of crack that occurs at the very edges of the asphalt pavement. Edge cracking usually takes place within a few feet of the outer edge of the pavement. This indicates poor asphalt mixing, construction, and application. It also means that the structure lacks adequate support along the edges.
