3 Types of Asphalt Cracks You Should Know
When it comes to maintaining an asphalt parking lot or roadway, cracks are one of the most common issues you’ll come across. While cracking will occur in any asphalt surface over time, understanding why cracks are developing will help you address repair needs in a timely manner. Here are common types of cracks you should be aware of.
A Guide to Asphalt Cracks to Watch Out For
1. Edge Cracks
As the name implies, edge cracks typically appear close to the edge of the paved surface. While this can occur because of poor lateral edge support during installation, environmental factors are also a major contributor to this type of crack.
Settling or drying soil, penetration from tree or shrub roots (which will need to be removed), and poor drainage are just a few potential culprits. These cracks can typically be repaired with an emulsion slurry.
2. Fatigue Cracks
Also known as alligator cracks, this type of cracking causes a scaly appearance. It typically occurs when the asphalt is overloaded (such as by a heavy semi-truck that exceeds the surface’s weight limit).
However, construction issues such as thin pavement, a weak base, or poor drainage could also contribute to this damage. Because these cracks indicate trouble with the base itself, the affected area should typically be replaced.
3. Reflection Cracks
Reflection cracks occur when you lay new asphalt over old, damaged pavement. The cracks and joints in the underlying pavement have a tendency to shift over time, which will then create cracks in the new asphalt. While this sometimes requires replacement of the pavement layer, many reflection cracks are small enough that they can be filled with sealant.
