Case Studies: Successful Asphalt Crack Repair Projects

Understanding Asphalt and Cracking

Asphalt is widely used for various construction applications, particularly for roadways and parking lots. However, over time, asphalt can develop cracks, which can lead to further deterioration if left unaddressed. Understanding the causes and types of asphalt cracks is crucial for effective repair and maintenance.

Cracking in asphalt can occur due to a range of factors, including excessive traffic, freeze-thaw cycles, moisture infiltration, and aging. The most common types of asphalt cracks include transverse cracks, longitudinal cracks, block cracks, and alligator cracks. Each type requires a specific repair approach to ensure a long-lasting solution.

The Importance of Crack Repair

Proper crack repair is essential to maintain the structural integrity of asphalt surfaces. Ignoring cracks can lead to more extensive damage, necessitating costly and time-consuming repairs or even complete resurfacing. By addressing cracks promptly, property owners can extend the lifespan of their asphalt surfaces, improve safety, and save money in the long run.

A successful crack repair project involves more than simply filling the cracks. It requires careful preparation, quality materials, and proper techniques to ensure a durable and aesthetically pleasing result. Fortunately, there are several proven methods and innovative products available to achieve effective asphalt crack repair.

Case Study 1: Routing and Sealing

In one successful asphalt crack repair project, a commercial parking lot with extensive alligator cracking was restored using a technique known as routing and sealing. This method involves cutting a groove along the length of the crack to create a reservoir for the sealant.

A specialized machine was used to route the cracks, ensuring a consistent width and depth. The debris was then removed, and a high-quality crack sealant was applied, filling the reservoir and preventing water penetration. The sealant not only repaired the visible cracks but also prevented further spreading and maintained the overall structural integrity of the parking lot.

Case Study 2: Crack Filling with Polymer Modified Asphalt

In this case study, a residential driveway with multiple transverse cracks was successfully repaired using a polymer modified asphalt (PMA) crack filler. PMA is a blend of asphalt, polymers, and other additives that enhance the performance and longevity of the repair.

The cracks were first cleaned and prepared by removing any loose debris and vegetation. After heating the PMA crack filler to the recommended temperature, it was applied directly into the cracks using specialized equipment. The filler seeped into the cracks, bonding with the surrounding asphalt and minimizing the risk of further cracking.

Case Study 3: Infrared Asphalt Patching

In some cases, infrared asphalt patching can be an effective solution for repairing large areas of cracked asphalt. This innovative method involves using infrared technology to heat the existing asphalt surface, allowing it to become workable again.

During this case study, a heavily cracked section of a city street was successfully repaired using infrared asphalt patching. The infrared machine was positioned over the damaged area, heating the existing asphalt to make it pliable. The damaged asphalt was then removed and replaced with fresh hot mix asphalt, seamlessly blending with the surrounding surface.


Successful asphalt crack repair projects require an understanding of the causes and types of cracks, as well as the appropriate repair methods and materials. By addressing cracks promptly and using proven techniques, property owners can ensure the longevity and safety of their asphalt surfaces.

Whether it’s routing and sealing, crack filling with polymer modified asphalt, or infrared asphalt patching, there are innovative solutions available to meet the specific needs of different crack repair projects. Consulting with experienced professionals and utilizing high-quality materials is crucial for achieving the best results and maximizing the lifespan of asphalt surfaces.
