Repair Techniques for Asphalt Cracks

Welcome to Big Easy Asphalt, your go-to resource for all your asphalt repair needs. In this guide, we will delve into the world of crack repair techniques for asphalt surfaces.

Cracks in asphalt can occur due to a variety of factors, such as weather conditions, heavy traffic, or the natural aging process.

It is crucial to address these cracks promptly to prevent further damage and ensure the longevity of your asphalt pavement.

Overview of Crack Sealing and Filling Methods

Crack repair for asphalt surfaces involves two primary methods: crack sealing and crack filling.

While these techniques are similar, they differ in the types of cracks they address and the materials used.

Crack Sealing

Crack sealing is a preventive maintenance measure used to address non-working cracks, which are cracks that show little to no vertical movement.

This method involves the application of a hot rubberized sealant into the crack, effectively sealing it from moisture and preventing further deterioration.

There are various types of sealants available for crack sealing, such as:

  • Rubberized Asphalt: This sealant is made from a blend of asphalt and rubber polymers, providing excellent flexibility and durability. It is commonly used for moderate to severe cracks.
  • Asphalt Emulsion: This sealant is water-based and provides good adhesion to asphalt surfaces. It is suitable for small to moderate cracks and is often used as a cost-effective option.
  • Fiberized Asphalt: This sealant contains fibers that enhance its strength and flexibility. It is ideal for wider cracks and offers improved resistance to cracking and aging.

Proper preparation is crucial before crack sealing. The crack should be thoroughly cleaned of debris, vegetation, and loose materials using high-pressure air or mechanical means.

This ensures better adhesion of the sealant and improves its overall effectiveness.

The sealant is then heated and applied using specialized equipment, ensuring a precise and consistent application.

Crack Filling

Crack filling is a reactive maintenance technique used to address working cracks, which are cracks that exhibit vertical movement.

These cracks are prone to expanding and contracting due to temperature fluctuations and the constant stress of traffic.

Crack fillers used in this method are designed to be more flexible, accommodating the movement of the crack without compromising the integrity of the repair. 

Some commonly used crack fillers include:

  • Asphalt-based Crack Fillers: These fillers are made from asphaltic materials and are ideal for narrow cracks. They provide excellent adhesion and flexibility, allowing for the expansion and contraction of the crack.
  • Rubberized Crack Fillers: This type of filler contains rubber polymers, which enhance its elasticity and durability. It is suitable for wider cracks and offers superior resistance to cracking and weathering.

Before applying the crack filler, the crack must be clean and dry. Loose materials, vegetation, and debris should be removed using appropriate methods.

The filler is then applied using a pour pot or a direct wand application, ensuring complete coverage of the crack.

Proper Preparation and Application Techniques for Crack Repair

Proper preparation and application techniques are crucial for effective crack repair.

Follow these guidelines for optimal results:

  1. Clean the Crack: Remove all debris, loose materials, and vegetation from the crack using high-pressure air, wire brushes, or other mechanical means. This ensures proper adhesion of the repair material.
  2. Create a Proper Reservoir: For crack sealing, widen the crack using a routing machine or crack saw to create a reservoir. This allows the sealant to properly adhere to the crack and improves the longevity of the repair.
  3. Use Appropriate Tools and Equipment: Invest in quality tools and equipment designed specifically for crack repair. This ensures accurate application and consistent results.
  4. Follow Manufacturer’s Instructions: Different crack sealants and fillers may have specific application guidelines. Always refer to the manufacturer’s instructions to ensure proper mixing, heating, and application techniques.
  5. Consider Weather Conditions: It is essential to take into account weather conditions when performing crack repair. Avoid applying sealants and fillers during rain, extremely hot temperatures, or freezing conditions, as it can affect the adhesion and performance of the repair material.

The work Big Easy Asphalt did for me was quick and efficient. They put down a nice layer of asphalt so my dad’s tractors have more space, which means he can store things inside without worrying about them being covered by dirt or grasses! The guy who did the job kept me updated throughout every step in order to make sure everything went smoothly. Highly recommended!
