Asphalt can last for decades with proper maintenance, but it’s essential to address damage promptly to prevent costly repairs. Crack filling, patching, and repaving are key methods to maintain asphalt surfaces, each suited to specific types of damage. Here’s a guide to understanding these repair techniques and when to use them.
Types of Asphalt Damage
To determine the right repair method, it’s important to identify the type of damage affecting your asphalt:
- Cracks: Small cracks are common and occur naturally due to traffic and weather. If left untreated, they can spread and form interconnected “spiderweb” patterns.
- Potholes: These deeper depressions form when the asphalt structure weakens, creating hazardous conditions for vehicles.
- Settlement: This occurs when the asphalt compresses unevenly, leading to dips and an unstable surface.
Crack Filling
Crack filling is the first line of defense against asphalt damage. This method is ideal for small cracks that haven’t yet spread or interconnected. While crack filling is not a substitute for preventive maintenance like sealcoating, it helps stop cracks from worsening. For best results, clean the cracks and fill them with high-quality crack sealant.
Patching
When damage extends beyond simple cracks—such as potholes or settlement—patching becomes necessary. This method addresses localized issues by removing the damaged asphalt and filling the area with new material. Patching is effective for isolated problems but isn’t suitable for widespread damage or interconnecting cracks. Regular maintenance, including sealcoating, should follow patching to ensure longevity.
Repaving
When crack filling and patching are no longer cost-effective, repaving may be the solution. Repaving is recommended when around 20% or more of your asphalt surface is compromised. This process involves laying a new layer of asphalt over the existing surface, addressing both cracks and settlement. However, if foundational damage is extensive, a complete replacement may be necessary.
Choosing the Right Repair Method
Each repair method has its purpose:
- Use crack filling for minor damage.
- Choose patching for more significant, localized issues.
- Opt for repaving when large portions of the asphalt are deteriorating.
