Repair Methods for Crumbling Asphalt

Before you begin repairing your asphalt, Asphalt Sealing will need to assess the damage to decide on the appropriate repair strategy. There are many ways to repair crumbling asphalt, including patching, resurfacing and overlays. Each method is unique and is perfect for different situations, however, picking the wrong one can result in short-term results before returning to its original state.

Asphalt Patching

Patching is a commonly used method to repair localized areas of damage on asphalt surfaces. It involves removing the damaged section and replacing it with new asphalt material. Patching is ideal for addressing small potholes, cracks, or localized deterioration.


  • Cost-effective solution for minor damage
  • Targets specific problem areas
  • Relatively quick to complete


  • May not provide a seamless appearance
  • Does not address underlying structural issues
  • Might require regular maintenance to prevent further damage

Asphalt Resurfacing

Resurfacing is a more comprehensive repair method that involves applying a new layer of asphalt on top of the existing surface. There are many reasons why you should resurface your asphalt, this technique is suitable for extensive damage or deterioration, providing a fresh, smooth, and uniform appearance.


  • Improves the overall appearance of the surface
  • Addresses multiple areas of damage at once
  • Strengthens the structural integrity of the pavement


  • Higher upfront cost compared to patching
  • Requires additional time for preparation and installation
  • May not be applicable for severely damaged or uneven surfaces

Asphalt Overlays

Overlays involve placing a new layer of asphalt over the existing pavement, providing a cost-effective and efficient solution for extensive damage. This method is frequently used when the base layers of the pavement are still structurally sound.


  • Extends the life of the existing pavement
  • Reduces the overall cost of repairs
  • Minimizes disruption during the repair process


  • May result in an increased height of the pavement surface
  • Requires proper surface preparation for optimal results
  • Not suitable for deteriorated base layers

When deciding on the most appropriate repair strategy for your crumbling asphalt, it’s crucial to consider factors such as the extent of damage, budget constraints, and long-term goals for your pavement. The team at Asphalt Sealing has extensive experience repairing all kinds of asphalt, we can assist you in making an informed decision based on your needs.

Assessing the Extent of Damage

Properly assessing the extent of damage on your asphalt surface is crucial for effective repair. Conducting a thorough inspection allows you to identify common issues such as crumbling, cracks and potholes, and understand the severity of the damage. Water damage, freeze-thaw cycles and heavy traffic can all be contributors to the deterioration of your asphalt.

Detecting cracks and crumbling early on is essential, as they can worsen over time and lead to more significant structural problems. By scheduling an evaluation of the condition of your asphalt, you can determine the appropriate repair methods and allocate the necessary resources.

Understanding the Causes of Crumbling Asphalt

Heavy traffic

This is one of the primary causes of asphalt deterioration. The constant weight and friction from vehicles can gradually wear down the surface, leading to cracks and potholes. Additionally, heavy trucks and buses exert more pressure on the pavement, accelerating the wear and tear process.

Freeze-Thaw Cycles

Temperature fluctuations play a significant role in asphalt deterioration. In Canada, where extreme weather conditions are common, the expansion and contraction of the pavement due to temperature changes can cause cracks and fractures. The repeated freezing and thawing cycles weaken the asphalt’s structure, leading to further deterioration over time.

Water Damage

When water seeps into the pavement through cracks or improper drainage, it can weaken the foundation and sub-base layers, causing the asphalt to deteriorate rapidly. Additionally, excess water or poor drainage can lead to the formation of potholes, further compromising the integrity of the pavement.

Asphalt Lifespan

Over time, the binder that holds the asphalt together starts to break down, affecting its flexibility and strength. As the asphalt becomes more brittle and less resilient, it becomes susceptible to cracks and crumbling.

How do you fix crumbling asphalt?

Crumbling asphalt can be repaired using various methods, including patching, resurfacing and overlays. By properly assessing the extent of damage and selecting the appropriate repair technique, you can effectively fix deteriorating surfaces and extend their longevity.

Why is my new asphalt crumbling?

New asphalt may begin to crumble due to various factors such as temperature fluctuations, weather conditions, or inadequate layering during installation. Additionally, the frequency and intensity of use can contribute to its deterioration. Regardless of the cause, addressing a crumbling asphalt driveway promptly is essential to prevent further damage.

Can you repair a crumbling driveway?

While minor cracks and crumbling can often be repaired by homeowners, extensive damage may warrant professional assistance. Hiring a professional is advisable for significant issues like large cracks or sections of the driveway sinking or crumbling, ensuring proper and long-lasting repairs.

Can I seal my crumbling driveway?

For minor cracks and damage, applying latex sealant or other suitable repairs can temporarily address the issue by covering the affected areas. This helps prevent water penetration and further deterioration caused by moisture. Asphalt patching is also an effective solution for small leaks or cracks, aiding in restoring the integrity of your driveway.

How do you bond old asphalt to new asphalt?

To enhance the bond between layers of asphalt pavement, the application of a tack coat is recommended. This inexpensive measure significantly improves the structural integrity of the pavement. Various types of tack coats and emulsions are available for this purpose, ensuring a strong and durable bond between old and new asphalt layers.

Should you seal new asphalt?

Sealing a new asphalt driveway is crucial for its longevity and appearance. Typically, once the asphalt has cured, which usually takes 30-90 days after installation, sealing should be performed. Seal coating provides essential protection against the elements, preserving the driveway’s integrity and aesthetic appeal for years to come. It’s generally recommended to seal a new asphalt driveway within its first year of installation to maximize its lifespan.
