Signs of Asphalt Cracking

Understanding Asphalt Cracking

Asphalt, also known as blacktop or pavement, is a commonly used material for roads, driveways, and parking lots. While asphalt is durable and cost-effective, it is not immune to damage. One of the most common issues faced with asphalt is cracking. Asphalt cracking can occur due to a variety of factors, including age, weather conditions, and inadequate maintenance. Understanding the signs of asphalt cracking is essential to prevent further damage and ensure the longevity of your asphalt surfaces.

Alligator Cracking

Alligator cracking is a type of asphalt cracking that resembles the scales of an alligator’s skin. It is characterized by interconnected cracks forming a pattern that resembles a series of small, irregular polygons. Alligator cracking is typically caused by structural failure, such as heavy traffic loads or inadequate pavement thickness. It is important to address alligator cracking promptly to prevent the spread of the cracks and further damage to the underlying pavement.

Longitudinal Cracking

Longitudinal cracking refers to cracks that run parallel to the direction of traffic flow. These cracks often occur due to the expansion and contraction of the asphalt pavement caused by temperature changes. Over time, longitudinal cracks can widen and allow water and debris to enter, leading to further deterioration of the pavement. Routine maintenance, such as crack sealing, can help prevent longitudinal cracking from worsening.

Transverse Cracking

Transverse cracking, also known as thermal cracking, refers to cracks that run perpendicular to the direction of traffic flow. These cracks are typically caused by temperature fluctuations and the resulting contraction and expansion of the asphalt. Transverse cracks are more commonly observed in colder climates where there are greater temperature variations. Regular maintenance, including crack filling, can help prevent transverse cracking from spreading and causing more significant damage.

Block Cracking

Block cracking is characterized by interconnected rectangular-shaped cracks that resemble the pattern of a checkerboard. It is often caused by the aging and hardening of the asphalt binder, which leads to the loss of flexibility. Block cracking is commonly seen in older asphalt pavements and can be exacerbated by heavy traffic and inadequate maintenance. Sealcoating and regular inspections can help mitigate block cracking and extend the lifespan of the pavement.


Potholes are depressions or craters in the asphalt surface that result from the deterioration of an underlying area. While not technically cracks, potholes often begin as small cracks that expand due to traffic and weather conditions. Potholes can cause significant damage to vehicles and pose a safety hazard to pedestrians. Timely repair and maintenance, such as patching and resurfacing, are crucial to prevent further degradation of the pavement.

In conclusion, cracks in asphalt can occur due to various factors, including alligator cracking, longitudinal cracking, transverse cracking, block cracking, and the formation of potholes. Recognizing the signs of asphalt cracking is essential in order to address and rectify the issues promptly. Regular maintenance, including crack sealing and patching, can prevent further damage and extend the lifespan of asphalt pavements. By understanding the different types of asphalt cracking and implementing appropriate maintenance strategies, you can ensure the durability and longevity of your asphalt surfaces.
