Blog Understanding the Different Types of Asphalt Cracks and How to Fix Them Dec 20, 2024

Asphalt is a durable and cost-effective solution for paving roads, driveways, and parking lots. However, like any material exposed to the elements and constant wear and tear, it can develop cracks over time. Understanding the different types of asphalt cracks and how to fix them is essential for maintaining the longevity and appearance of your surfaces. At Clear Choice Asphalt Services, we believe that informed customers are empowered customers. Below, we’ll explore common asphalt cracks and some practical solutions.

One of the most common types of asphalt cracks is the *alligator crack*. Named for its resemblance to alligator skin, this pattern of interlinked cracks is usually a sign of underlying problems, such as heavy traffic load or poor drainage. To address alligator cracks, patching with an asphalt overlay may suffice for minor cases. However, more severe instances might require removing the damaged area and replacing it with new asphalt. A professional assessment is crucial to determining the appropriate solution.

*Longitudinal cracks* are another frequent issue, running parallel to the pavement's centerline. These cracks often result from improper paver operation or temperature fluctuations causing asphalt contraction. To repair longitudinal cracks, the sealant should be applied to prevent water from penetrating and causing further damage. Timely sealing can significantly extend the life of your pavement and prevent more costly repairs down the line.

*Transverse cracks* run perpendicular to the pavement's centerline and are typically caused by shrinkage of the asphalt layer due to temperature variations. These are typically less severe than alligator cracks, but they still need attention to prevent moisture infiltration. Sealing transverse cracks with a hot-applied rubberized sealant can help maintain the surface's integrity and prevent the spread of damage.

*Edge cracks* often appear between the pavement and its edge, usually due to weak base support or poor drainage. These cracks can be exacerbated by heavy vehicles or inadequate shoulder support. The best approach to fix edge cracks includes improving drainage and fortifying the base. Filling them with high-quality crack filler helps provide additional protection from the elements.

Potholes are another familiar sight on poorly maintained asphalt surfaces, usually a result of untreated cracks and moisture infiltration. Fixing potholes typically involves cleaning the hole, applying a tack coat, and filling it with an asphalt patch. Proper compaction is essential to ensure the patch merges seamlessly with the rest of the surface.

Preventative maintenance is key to avoiding significant repair costs and ensuring that your asphalt surfaces remain in top condition. Regular inspections can help identify minor cracks before they expand and require costly interventions. Implementing a seal coating every few years can also provide a protective barrier that shields the pavement from water, oil, and UV damage.

In conclusion, being proactive about asphalt maintenance can save you time and money. Recognizing early signs of cracking and understanding the right ways to address them can make all the difference in preserving your pavement’s quality.
