Maintaining a smooth and durable asphalt surface is crucial for both appearance and functionality. However, one of the most common challenges faced by asphalt surfaces is cracking. Understanding asphalt crack repair is essential to extend the life of your pavement and ensure its safety. At Hyder Paving & Construction Co., we’re committed to helping you keep your surfaces in top shape. Let’s dive into the common issues related to asphalt cracks and how you can prevent them effectively.
What Causes Asphalt Cracks?
Before diving into repair strategies, it’s vital to understand the root causes of asphalt cracks. Identifying these factors can aid in both repairing existing damage and preventing future issues from arising. Here are some common causes of asphalt cracks:
1. Weather Conditions
Weather fluctuations play a significant role in contributing to asphalt cracks. The freeze-thaw cycles, which are common in many regions, cause the asphalt to expand and contract repeatedly. As temperatures drop, water infiltrates small crevices in the asphalt and freezes, expanding the cracks. When the ice melts, the asphalt contracts, leading to a loosening of the surface. Over time, this continual cycle leads to cracks as the material is stressed beyond its limits, compromising its structural integrity.
2. Poor Installation
Improper installation is another critical factor that can lead to premature cracking of asphalt surfaces. This might occur due to several issues, such as inadequate compaction during the laying process, the use of low-quality materials that are unable to withstand environmental stressors, or a lack of proper drainage systems to divert water away from the surface. When the base is not well-prepared or the asphalt is too thin, the surface becomes vulnerable to damage and eventual cracking.
3. Heavy Traffic Loads
Asphalt surfaces subjected to repeated heavy loads can experience significant stress, leading to fatigue and cracking. This is especially prevalent in parking lots, highways, and roads that frequently accommodate heavy vehicles like trucks and buses. The constant weight from heavy loads slowly weakens the asphalt, causing cracks that can spread and get worse if not fixed quickly.
4. Lack of Maintenance
Neglecting regular maintenance is a common reason small cracks worsen over time. Without timely intervention, such as sealing or filling these minor defects, they can expand and lead to more significant damage that requires extensive repair. Regular maintenance, including inspections and minor repairs, can help preserve the integrity of the asphalt surface and extend its lifespan, preventing more costly issues in the future.
Common Types of Asphalt Cracks
As you plan for asphalt crack repair, it’s helpful to understand the various types of cracks that can occur:
Alligator Cracks
These resemble the scales of an alligator and are often a sign of underlying structural problems. They usually indicate issues with the base or sub-grade of the pavement.
Block Cracks
Block cracks form large rectangular sections and typically result from temperature fluctuations. Unlike alligator cracks, they are not load-associated.
Edge Cracks
Found near the edges of the pavement, these cracks are often caused by poor drainage or lack of support at the sides.
Longitudinal Cracks
Running parallel to the pavement centerline, these cracks can result from poor joint construction or temperature changes.
Transverse Cracks
Perpendicular to the centerline, these cracks are usually due to thermal stress or shrinkage.
The Importance of Timely Asphalt Crack Repair
Addressing cracks in a timely manner is crucial for maintaining the longevity and durability of your pavement. Cracks, if left unattended, can allow water to seep in, leading to water infiltration. This not only exacerbates the existing damage but can also cause the cracks to expand further, especially during freeze-thaw cycles. Over time, this can weaken the strength of the whole pavement, causing larger and more costly repairs. Regular maintenance and implementing timely intervention can help prevent these issues.

Preventing Asphalt Cracks
Asphalt cracking is a common issue that can severely impact the integrity and lifespan of pavement. While some cracking is inevitable due to natural wear and tear, there are numerous proactive measures you can take to minimize their occurrence and impact, preserving the quality and appearance of your surfaces for longer.
Regular Inspections
Conducting regular checks on your asphalt surfaces is crucial. By identifying small cracks early on, you can address them before they develop into larger, more costly repairs. Frequent inspections allow for timely interventions, which can significantly extend the life of your pavement and save money in the long run.
Sealcoating
Applying a sealcoat is an essential maintenance step that acts as a protective layer against various damaging elements, such as moisture, UV rays, and harsh chemicals. This process not only enhances the overall appearance of your asphalt but also significantly improves its durability, making it a cost-effective way to extend the longevity of your pavement.
Proper Drainage
Ensuring your pavement has adequate drainage is vital for its durability. Good drainage prevents water pooling, which can lead to rapid deterioration and significant cracking. Properly designed drainage systems redirect water away from the surface, reducing the risk of damage and helping maintain the structural integrity of the pavement.
Quality Installation
Investing in quality right from the outset is fundamental. This includes using high-grade materials and ensuring proper compaction and thickness during installation. A well-installed asphalt surface is less susceptible to wear and tear, providing a solid foundation that resists cracking and other forms of damage over time.
Weight Management
Managing the weight of vehicles on your asphalt surfaces is another key factor in preventing cracks. Heavy vehicles impose significant stress on the pavement, especially in parking areas. To minimize this, consider implementing designated areas for heavy vehicles and limiting their access to certain parts of the surface. This approach reduces stress and helps maintain the overall health of your pavement.
