How to Repair Cracks in Asphalt Surfaces 1

Understanding Asphalt Cracks

Asphalt is a commonly used material for driveways, parking lots, and roads due to its durability and ability to withstand heavy traffic. However, over time, asphalt surfaces can develop cracks due to various factors such as weather changes, heavy loads, and aging. These cracks not only affect the appearance of the surface but also pose a risk of further damage if left untreated. Understanding the types of cracks and their causes is essential before proceeding with the repair process.

Identifying the Types of Cracks

Before repairing asphalt cracks, it is crucial to identify the types of cracks present on the surface. The three most common types of asphalt cracks are:

  • Alligator Cracks: These cracks resemble the skin of an alligator, with interconnected cracks forming a web-like pattern. They are typically caused by heavy loads and structural issues.
  • Linear Cracks: These cracks occur in straight lines and are often caused by temperature fluctuations, moisture, or improper installation.
  • Potholes: Potholes are circular or square-shaped depressions in the asphalt surface. They are usually caused by water penetration and freeze-thaw cycles.
  • Repairing Small Cracks

    If the cracks on the asphalt surface are small and less than a quarter-inch wide, they can be repaired using simple techniques. Here’s how:

  • Clean the crack: Remove any debris, loose asphalt, or vegetation from the crack using a broom or brush. A pressure washer can also be used for thorough cleaning.
  • Seal the crack: Apply a crack filler or asphalt patching compound into the crack, ensuring the material is slightly above the surface. Use a trowel to smooth the filler and create a seamless finish.
  • Allow curing: Let the repair material cure according to the manufacturer’s instructions. This usually takes a couple of hours or overnight.
  • Seal the surface: Once the crack repair has fully cured, apply a sealcoat to the entire asphalt surface to provide additional protection against future cracks and deterioration.
  • Tackling Larger Cracks and Potholes

    For larger cracks and potholes, a more extensive repair approach is required. Follow these steps to effectively repair bigger asphalt damage:

  • Cut and clean the damaged area: Use a saw or chisel to cut the edges of the crack or pothole, creating a clean and defined shape. Remove any loose asphalt and debris.
  • Apply a bonding agent: Before applying the patching material, apply a bonding agent to enhance adhesion between the existing asphalt and the patch. Follow the manufacturer’s instructions for proper application.
  • Fill the damaged area: Fill the crack or pothole with an asphalt cold patch material, compacting it firmly with a tamper or hand roller. Add the patch material in layers until the repair matches the surrounding asphalt surface.
  • Compact and smooth: Compact the patch material using a vibratory plate compactor to ensure it is tightly packed and level with the rest of the surface. Use a trowel to smooth out any unevenness.
  • Allow curing: Allow the repair to cure for the recommended time, which is typically 24 to 48 hours, before allowing traffic on the surface.
  • Preventing Future Cracks

    While it is crucial to repair existing cracks, taking preventive measures can significantly reduce the occurrence of future cracks. Here are some preventive maintenance tips:

  • Regularly inspect the asphalt surface for signs of cracks or damage.
  • Sealcoat the surface every two to three years to protect it from moisture, UV rays, and traffic wear.
  • Ensure proper drainage to prevent water from accumulating on the surface.
  • Avoid overloading the asphalt surface beyond its weight-bearing capacity.
  • Regularly remove snow and ice during colder months using non-abrasive materials.
  • The Advancements in Asphalt Crack Repair

    In recent years, advancements in asphalt crack repair techniques and materials have made the process more efficient and long-lasting. Two notable innovations include:

  • Crack Sealing: This method involves filling and sealing the cracks with specialized rubberized materials. The process prevents water infiltration, extends the life of the asphalt surface, and reduces the formation of new cracks.
  • Crack Routing: Crack routing is a technique used to widen and reshape the cracks before filling them. By creating a larger reservoir for the crack sealant, crack routing increases the effectiveness and durability of the repair.
  • With these innovations, asphalt crack repair has become more cost-effective and environmentally friendly, helping to prolong the lifespan of asphalt surfaces and reduce the need for frequent repairs.


    Repairing cracks in asphalt surfaces is essential for maintaining the appearance and structural integrity of the pavement. By understanding the types of cracks, using appropriate repair techniques, and implementing preventive maintenance, you can ensure the longevity of your asphalt surface.
