Understanding The Different Types Of Pavement Cracking

Pavement cracking is a common problem that every property owner faces sooner or later. The cracking appears due to a variety of reasons such as age, weather, excessive vehicle load, and more. If left untreated, cracks can worsen over time and result in potholes, leading to accidents. It is therefore necessary to understand the primary types of pavement cracking to decide the best course of action. In this blog, we’ll be discussing the various types of pavement cracking that you might encounter.


1. Alligator Cracking

Alligator cracking is an alarming form of pavement failure in which the surface begins to resemble the scales of an alligator or crocodile. This type of cracking is caused due to insufficient load-bearing capacity, drainage problems, or poor construction in the sub-grade layer. Alligator cracking can worsen over time and result in the form of potholes.

2. Transverse Cracking

Transverse cracking looks like a straight line, perpendicular to the direction of pavement. This type of pavement cracking occurs due to temperature fluctuations, moisture changes, and settling of aggregate over time. Transverse cracks are prone to water penetration and result in the growth of potholes.

3. Longitudinal Cracking

Longitudinal cracking is another type of pavement cracking where the crack follows the direction of the pavement. The main cause of this type of crack is the excessive downward movement of the pavement/base course, irregular shrinkage in the asphalt mix, and improper paving materials. Longitudinal cracking can also accelerate with age and lead to serious pavement damage.

4. Block Cracking

Block cracking is an interconnected series of rectangular/cracked blocks on the pavement surface. This type of cracking commonly occurs in older pavements experiencing temperature fluctuations. Block cracking can become a serious problem that could lead to potholes and substantial pavement failure if not addressed early on.

5. Edge Cracking

Edge cracking is a common type of pavement distress that appears parallel to the pavement edge. The main reason behind this type of crack is improper drainage, load repetition, and frost damage. Edge cracking can be severe if left untreated and lead to further pavement damage.



Cracks may seem like a small issue in pavement, but they can lead to bigger problems in the future if left untreated. Proper identification and timely treatment of cracks can save you from costly repairs and legal consequences. Understanding the different types of pavement cracking can help you identify the problem early on and avoid more significant damages.
