Common Causes of Asphalt Cracks

Asphalt cracks are commonly caused by various factors such as poor foundation, heavy vehicles, and tree roots. When the foundation of the asphalt isn’t properly constructed or has weakened over time, it becomes more susceptible to cracking. Heavy vehicles, especially those with excessive weight or frequent traffic, can exert significant pressure on the surface, leading to cracks. Additionally, tree roots that grow beneath the asphalt can push against the pavement, causing it to crack.

Another factor that contributes to asphalt cracks is the freeze-thaw cycle. During winter, water seeps into the cracks and freezes, causing the asphalt to expand. As the ice melts, the asphalt contracts, resulting in deep cracks. Weeds or vegetation that grow in the cracks can exacerbate the problem. Their roots can penetrate the asphalt, widening the cracks and causing additional damage to the surface.

Natural aging and deterioration, heavy traffic, and extreme weather conditions also play a role in asphalt crack formation. Over time, asphalt becomes more brittle and prone to cracking. Heavy traffic, especially in areas with frequent stopping and starting, can put stress on the surface, leading to cracks. Extreme weather conditions, such as intense heat or cold, can further weaken the asphalt, making it more susceptible to cracking.

To prevent further damage, regular crack repair and maintenance are essential. Timely asphalt crack repair and asphalt driveway repair can help prolong the lifespan of the pavement and prevent deep cracks from forming.

Surface Preparation for Crack Repair

When preparing the surface for crack repair on your asphalt, it’s crucial to thoroughly clean the crack and remove any debris or vegetation that may hinder the effectiveness of the repair. To do this, you can use a wire brush, screwdriver, or trowel tool to scrape out any dirt or loose material from the crack.

Be sure to remove any vegetation that may have grown in the crack as well. Once the crack is cleaned, you can use a garden hose or pressure washer to wash out any remaining debris. It’s important to allow the crack to dry completely before applying any crack filler. This ensures that the filler adheres properly to the surface.

Before applying the crack filler, shake the bottle thoroughly to ensure proper mixing of the product. Then, cut the top of the spout to the desired width, making sure it’s smaller than the crack you’re repairing.

Proper Crack Size Assessment

How can you accurately assess the size of a crack in asphalt? Proper crack size assessment is crucial for effective asphalt repair. By accurately measuring the crack width and length, you can determine the appropriate repair method and materials needed. Here’s a simple guide to help you assess crack size:

Crack Width (inches)Crack SeverityRecommended Repair Method
Less than 1/4Narrow or hairlineCrack sealing or crack filling
1/4 to 1ModerateCrack filling or patching
Greater than 1WidePatching or removal and replacement

To measure the width of a crack, use a ruler or a crack-width gauge. Place the gauge perpendicular to the crack and record the measurement. For longer cracks, measure the length using a tape measure or a measuring wheel.

Once you have assessed the crack size, you can choose the most appropriate repair method. Narrow or hairline cracks can be sealed or filled using specialized crack sealants or fillers. Moderate cracks may require crack filling or patching materials. Wide cracks may need patching or complete removal and replacement of the damaged asphalt.

Accurate crack size assessment allows for targeted and efficient repairs, ensuring the longevity and durability of your asphalt surface. Remember to follow proper repair procedures and use high-quality materials to achieve the best results.

Repairing Cracks Less Than 1/2 Inch Wide

Now that you have accurately assessed the size of the crack in your asphalt, it’s time to address the next step – repairing cracks that are less than 1/2 inch wide. These smaller cracks can be easily filled using a crack filling machine and hot pour crack filler. Before you begin, make sure to clean the crack thoroughly by using a wire brush or broom to remove any dust and debris. This will ensure a strong bond between the crack seal and the asphalt surface.

Once the crack is clean, you need to ensure that the surface is dry. Moisture can prevent the crack filler from adhering properly. So, take the time to dry the area completely before proceeding with the repair.

For cracks less than 1/2 inch wide, it’s recommended to use a hot pour crack filler. This can be applied with a caulking gun or poured directly onto the crack. Make sure to fill the crack until it’s approximately 1/4 inch deep. This will provide enough material to form a strong, durable seal.

After applying the hot pour crack filler, use a u-shaped squeegee to spread and level the filler. This will ensure an even distribution and a smooth finish. Allow the crack seal to dry completely before using the repaired area.

To enhance the durability of the repaired line, top it with sand. This will help protect the sealant and extend its lifespan. By following these steps, you’ll effectively repair cracks that are less than 1/2 inch wide and maintain the integrity of your asphalt surface.

Repairing Cracks More Than 1/2 Inch Wide

For cracks wider than 1/2 inch, it’s recommended to either use rubberized hot pour crack filler or hire a professional for repair. These wider cracks require special attention due to their size and potential for further damage.

Here are some important steps to follow when repairing cracks more than 1/2 inch wide:

  • Proper surface preparation: Before applying any filler, it’s crucial to prepare the surface properly. This involves cleaning the crack thoroughly, removing any debris or loose material, and ensuring the area is dry.
  • Choosing the right sealant: Wider cracks require a more durable and flexible sealant to withstand the stress and movement of the asphalt. Rubberized hot pour crack filler is an excellent choice as it provides a long-lasting repair.
  • Spreading and leveling the filler: When filling cracks wider than 1/2 inch, use a u-shaped squeegee to spread the filler evenly. This ensures proper coverage and helps level the surface for a smoother finish.
  • Allowing sufficient drying time: After applying the crack filler, it’s important to allow it to dry completely before allowing any traffic over the repaired area. This ensures a strong bond and prevents premature failure.


In conclusion, the Pro Asphalt Crack Repair Guide equips readers with the knowledge and tools to effectively repair and maintain asphalt surfaces.

By understanding the common causes of cracks and following the proper assessment and repair techniques, individuals can prevent further damage, extend the lifespan of their asphalt, and save money on costly repairs.
