Crack sealing is a critical part of asphalt maintenance, ensuring your paved surfaces remain durable and safe for years to come. It protects against water infiltration, which can lead to deeper damage and significantly shorten the lifespan of your asphalt. But how often should you do crack sealing in asphalt? The answer depends on several factors, including climate conditions, traffic load, and the general condition of the asphalt.
Whether you manage a driveway, parking lot, or roadway, scheduling regular crack sealing helps maintain the integrity of your pavement while saving you the cost of premature replacements. At Topwest Asphalt, we bring decades of experience and cutting-edge technology to every project, ensuring professional results that last.
Why Asphalt Cracks Over Time
Cracks in asphalt are inevitable due to natural aging and external stressors. Here are the key reasons they occur:
- Oxidation: Over time, exposure to UV rays causes the asphalt surface to oxidize. This results in a brittle, dry layer that is more prone to cracking.
- Temperature Fluctuations: Seasonal changes can cause the asphalt to expand in the summer and contract in the winter, leading to cracks forming.
- Water Penetration: Cracks allow rainwater to seep into the sub-base, eroding it and destabilizing the pavement’s foundation.
- Heavy Traffic Loads: Repeated pressure, especially from large vehicles, can stress the pavement, producing cracks.
Crack sealing stops the deterioration in its tracks by keeping water and debris out, preventing further expansion of cracks and the formation of potholes.
Signs You Need Crack Sealing
While cracks in asphalt are a visible sign that action is needed, there are certain indicators to help you determine when it’s time to seal them:
- Small cracks are worsening: If you notice new cracks forming or existing ones expanding, it’s time to act.
- Rainwater seeping into cracks: Water infiltration is one of the leading causes of progressive pavement damage. Take action before it compromises the sub-base.
- The asphalt looks mottled or spider-webbed: A dry, cracked surface suggests the need for crack sealing to restore its integrity.
Sealing cracks early and regularly ensures a smooth, longer-lasting surface.
Benefits of Regular Crack Sealing
Addressing cracks proactively yields multiple advantages over waiting until the damage requires costly repairs. Here’s why regular crack sealing is essential:
- Extends Lifespan: Prevents cracks from worsening, extending the life of your asphalt surface.
- Prevents Water Damage: Stops water from entering the sub-base and causing significant structural damage.
- Cost-Effective: Crack sealing is a much simpler and less expensive process compared to full-scale replacement.
- Improves Appearance: Sealed cracks result in a cleaner, more professional-looking pavement.
By regularly performing crack sealing, you’re effectively protecting your investment in the asphalt while ensuring the surface remains safe and functional.
Crack Sealing and Maintenance Frequency
The frequency of crack sealing depends on the following primary factors:
- Traffic Volume: High-traffic areas like parking lots and roadways may require sealing every 1-2 years. Residential driveways with lower traffic might only need maintenance every 3 years.
- Weather and Climate: Regions that experience freeze-thaw cycles will require more frequent repairs, as the expansion and contraction stresses the pavement.
- Inspection Results: Professional inspections can identify signs of wear before they become severe. Conduct a thorough assessment yearly to determine if sealing is necessary.
If you’re unsure how often you should repair cracks in asphalt, consult experts like Topwest Asphalt. Our professional evaluations take all factors into account to create a tailored maintenance plan for your asphalt surface.
The Topwest Asphalt Advantage
At Topwest Asphalt, we ensure that every aspect of crack sealing is handled with precision to maximize its effectiveness. Here’s what sets us apart:
- Crack Routing: Before sealing, we route the cracks into a V-shape to allow the sealant to properly fill and adhere. Skipping this step risks sealant failure and compromises the asphalt’s lifespan.
- Thorough Cleaning: Dirt, debris, and vegetation can hinder the effectiveness of sealant application. We use professional tools to clean every crack thoroughly before sealing.
- Hot Rubber Sealants: We use high-grade, hot rubber sealants that expand and contract with the asphalt, ensuring durability even through extreme temperature fluctuations.
- Precision and Equipment: Using state-of-the-art equipment and techniques, we finish the repair seamlessly while maintaining a flush surface.
