What Causes Alligator Cracking

What Causes Alligator Cracking

One of the most evident signs of asphalt deterioration is when you see alligator cracking on your surface. Also known as fatigue cracking or crocodile cracking, these destructive patterns on the pavement also resembles the crocodile skin.

Unfortunately, alligator cracking on your commercial or residential property is more than just an eye-sore. It often starts in the passage of wheels as a longitudinal crack connects with traverse cracks and ends as an alligator crack after severe distress.

Not to forget, ignoring the alligator cracking could accelerate the surface deterioration, resulting in costly repairs. However, before planning for the alligator crack repair, it is essential to diagnose the cause of the crack and its effects on the pavement foundation.

The most common alligator crack causes include:

1. Heavy Traffic Load

Generally, alligator cracking is a structural failure associated with traffic load. However, it can also be strongly influenced by environmental and other effects, while traffic load remains the direct cause.

Often, overloading occurs because the base or subbase inadequately supports the surface layer and cannot withstand loads usually experienced. Hence, you see alligator cracks forming on the asphalt surfaces.

2. Poor Drainage

Poor drainage in the roadbed is the most common cause of the base or subbase degradation, resulting in alligator cracks visible on the surface.

Moreover, the heavy spring thaw also acts like a poor drainage cause where the minor cracks are filled with water that later weakens the sub-base of your pavement.

3. Deficient Compaction During Construction

Another possible cause of alligator cracking is insufficient compaction during the pavement installation and construction. Here, poor adhesion between the asphalt and aggregate allows the aggregate on the surface to dislodge.

If left untreated, it reduces the thickness of the pavement and compromises the affected part’s ability to support its designed load. This later leads to the rapid development of alligator cracks in the surface.

4. Edge Cracking

Edge cracking is the formation of crescent-shaped cracks near the edge of a road. A lack of roadside support causes it, sometimes due to poorly drained or weak shoulders.

If left untreated, they eventually start looking like alligator cracks. However, like alligator cracking in the wheels’ passage, poor drainage is one of the leading causes of edge cracking, which accelerates pavement deterioration.

Since alligator cracks are usually more profound than any typical surface damage you come across, it is advisable to seek expert surface repair and maintenance services.
