Are Cracks in Asphalt Normal? A Professional Guide for Homeowners and Business Owners
Understanding Asphalt Deterioration: Are Cracks Normal?
As a property owner, you have likely noticed small fissures or cracks appearing on your asphalt driveway or commercial parking lot over time. It is a common question among our clients at Hick's Paving: Is this normal? The short answer is that while some minor weathering is inevitable as asphalt ages, not all cracks are created equal. Understanding the difference between surface-level fatigue and structural failure is the first step in protecting your property investment.
Asphalt is a flexible pavement material, meaning it is designed to expand and contract with changing temperatures. However, even with this flexibility, various environmental factors, oxidation, and heavy loads can lead to cracking. As a three-generation family-owned business operating since 1950, Hick's Paving has seen every type of pavement damage imaginable. We want to help you distinguish between manageable maintenance issues and those that require professional intervention.
Common Types of Asphalt Cracking
To determine if your cracks are "normal," you must first identify the type of distress occurring on your surface. Not all cracks are the same, and they often signal different underlying problems.
1. Hairline Cracks and Surface Weathering
Hairline cracks often appear as a result of oxidation, where the sun’s UV rays dry out the asphalt binders. These small, shallow cracks are generally considered a normal part of the aging process. If your pavement is several years old and showing minor surface cracks, it may be time for sealcoating. Sealcoating acts as a protective barrier, preventing further moisture penetration and keeping the asphalt flexible.
2. Block Cracking
Block cracking creates a pattern that looks like large, interconnected rectangles or squares. This is typically a sign that the asphalt binder has hardened over time and lost its elasticity. If you see this, it is a sign that your pavement has reached the end of its natural life cycle and requires more than just a quick patch.
3. Alligator Cracking
This is the most serious form of pavement distress, resembling the scaly skin of an alligator. This type of cracking occurs when the sub-base beneath your asphalt has failed. Because the foundation can no longer support the weight of traffic, the asphalt surface cracks under the pressure. At Hick's Paving, we advise clients that alligator cracking usually indicates a need for deeper repairs, such as excavation and base reconstruction, rather than a simple surface fix.
When Should You Call a Professional?
While DIY maintenance can handle very minor repairs, there comes a point where professional expertise is non-negotiable. If you ignore cracks, moisture will seep into the sub-base, leading to potholes, crumbling, and a much higher repair cost in the future. As a company that has served the Lehigh Valley area for decades, we at Hick's Paving know that proactive maintenance is significantly cheaper than total resurfacing.
You should consider contacting a professional if you notice the following:
Deep or Wide Cracks: Any crack wider than a quarter-inch should be sealed professionally to prevent water from reaching the base.
Vegetation Growth: If weeds or grass are growing through your cracks, it indicates that the structural integrity of the pavement has already been compromised.
Potholes: A pothole is the final stage of neglected cracking. Once a pothole forms, it can damage vehicle tires and pose a safety risk to pedestrians.
Soft Spots: If your pavement "gives" or feels spongy when you walk on it, the base material is likely saturated with water.
The Importance of Proactive Maintenance
Maintaining your asphalt is about more than just aesthetics; it is about extending the lifespan of your property. Regular inspections and professional sealcoating are the best defenses against environmental wear. By addressing cracks early, you avoid the massive expense of removing and replacing large sections of asphalt.
