4 Types of Asphalt Cracks and Ways To Fix Them

When it comes to your business’s exterior, the driveway and parking lot often take center stage. However, its once-smooth surface may develop unsightly asphalt cracks over time due to the elements. Property managers are familiar with the creeping disrepair that can affect a seemingly solid driveway. Not only do these cracks mar your property’s appearance, but they can also indicate more significant structural issues if you don’t address them.

Here's a quick guide to understanding the types of asphalt cracks you might encounter and the steps to take to fix them efficiently.

1. Alligator Cracks

If you see a pattern of interconnected cracks like scales, it’s “alligator” or “fatigue” cracking. Causes include a weak foundation, heavy loads, and aging. Untreated, these cracks can cause pavement failure, allowing water to penetrate and erode the base. Repair options include professional overlays or patching for small areas.

2. Block Cracks

Block cracks are typically rectangular and in low-traffic parking lots. They result from the drying and hardening of the asphalt mixture over time, which causes it to shrink and crack. While not as severe as alligator cracks, they still require attention. Regular sealing can prevent these cracks from turning into larger problems. But for wider block cracks, professional resurfacing may be necessary.

3. Edge Cracks

Edge cracks are a type of asphalt crack that appears along pavement edges. They often result from drainage issues, the lack of gutters on curbsides, or simply aging. If neglected, they can erode the subbase and cause the pavement edges to crumble. Prompt filling is crucial, and a professional assessment is necessary if erosion has occurred.

4. Linear Cracks

Linear cracks are long, single lines running throughout your asphalt surface. Potential culprits include the shrinking of the asphalt layer, temperature fluctuations, or even the incorrect installation of the initial surface. For these, a select range of sealants might be your best bet to prevent moisture penetration and eventual unwelcome growth into larger, more complex fissures.

Preventing Future Cracks

After the repairs are over, the best course is to look forward. Regular asphalt maintenance tasks, such as annual sealing and addressing smaller cracks as they appear, are invaluable in extending its life and keeping it aesthetically pleasing. Simple steps like clearing debris, directing water flow away from edges, and shoring up any areas of concern can go a long way in avoiding future headaches.

Choosing the Right Products for Lasting Repairs

Lasting repairs hinge on the quality of the products you use. When selecting asphalt crack repair products, focus on those designed for durability and appropriate for the extent of your repair needs. Ensure the product offers the necessary weather resistance and flexibility to accommodate the asphalt’s expansion and contraction.

Understanding the types of asphalt cracks and the ways to fix them might seem challenging, but being proactive now can prevent expensive repairs later. Your property's pavement health and appearance deserve attention. With these tips, you're closer to achieving crack-free pavement.
