Identifying Different Types of Pavement Damage

Your pavement will see a lot of use over the years, making it vulnerable to damage. Cracks occur in your asphalt pavement for several reasons. It is crucial to determine the current condition of the pavement and the cause of any damage. The better you maintain your pavement, the longer it will last.

 

The best way to maintain your pavement is to look into the structure, roughness, and damage. Regular inspection can help prevent further damage to your asphalt project. Pavement can be damaged due to many different factors, but harsh weather is one of the leading causes. Freezing weather and salting, in particular, can significantly deteriorate your asphalt pavement.

Here’s how to identify the cause of your asphalt paving damage.

 

Identifying Different Types of Pavement Damage

 

Let’s take a closer look at the different types of pavement damage and what causes them.

 

Fatigue or Alligator Cracking

 

This type of damage is known as alligator or fatigue cracking because it resembles the scales on a reptile’s back or the cracking you see when a hard-boiled egg is broken. This issue is most commonly a load-related structural failure. It is often related to a collapse of the surface due to traffic loading.

 

Causes:

 

There can be many causes of fatigue or alligator cracking like:

 

Weak Surface

 

A weak surface is one of the many reasons to cause fatigue cracking.

 

Poor Drainage

 

Poor drainage may cause damage to the pavement.

 

Weather Conditions

 

Harsh weather can quickly deteriorate pavement.

 

Block Cracking

 

This type of cracking resembles squares or circles of cracks in your asphalt pavement. This type of damage usually on a large surface area. The cracks are interconnected to each other, dividing the pavement into small blocks.

 

Causes:

 

The most common reasons are:

 

Asphalt Material

 

If the asphalt material hardens, then it can cause block cracking.

 

Pavement Installer

 

Block cracking is an indication of the pavement installer using an old mix that was too dry when the asphalt surface was initially laid.

 

Temperatures

 

Temperatures that are too hot or cold can cause the asphalt material to shrink, ultimately resulting in block cracking.

 

Edge Cracking

 

Edge cracks are continuous cracks located within approximately 2 feet of the pavement edge. They can be seen along the outside edges of your pavement. They are usually long and run with the road. They typically have lateral support.

 

Causes:

 

The most common causes of edge cracking are:

 

Poor Drainage

 

Poor drainage is one of the main reasons for edge cracks.

 

The Underlying Soil

 

If the soil under the road dries, it can cause edge cracks.

 

Heavy Traffic

 

Heavy vegetation and heavy traffic on the road also cause edge cracks.

 

Slippage Cracks

 

Slippage cracks look like something slipped along the pavement’s surface. Their shapes are like crescent or half-moon and characterized by deep, open gaps.

 

Causes:

 

The most common cause is:

 

Weak Bonding

 

Weak or insufficient bonding between the layers causes slippage cracking. Weak bonding may be due to dirt, oil, or other impurities preventing adhesion between the layers.
