Asphalt Driveway Crack Repair and Maintenance

As road managers responsible for maintaining asphalt surfaces, ensuring the longevity and safety of roads and driveways is of paramount importance. Asphalt driveways suffer from large cracks that, if not addressed promptly and effectively, can lead to more extensive damage and pose safety hazards for drivers.

How to Repair Large Cracks in Asphalt Driveway?

1. Identifying the Issue

Before embarking on repair efforts, it’s essential to identify the types and severity of cracks. Common types of cracks in asphalt include:

• Alligator Cracks: Resemble a reptile’s skin and indicate structural issues.
• Transverse Cracks: Run perpendicular to the road’s direction and are often caused by temperature fluctuations.
• Longitudinal Cracks: Run parallel to the road’s direction and are typically caused by traffic loads.
• Block Cracks: These appear as interconnected rectangles and are usually due to improper asphalt curing.

2. Safety Precautions

Before starting any repair work, prioritize safety. Road repair crews should:

• Wear appropriate personal protective equipment (PPE), including high-visibility clothing, gloves, and safety glasses.
• Use warning signs, cones, and barricades to protect workers and drivers.

3. Repair Procedures

Cleaning the Crack

• Remove debris, dirt, and vegetation from the crack using a broom or air blower.
• Use a high-pressure washer or wire brush to clean the crack thoroughly.

Preparing the Crack

• For structural cracks, widen them using a cold chisel or saw to create a “V” shape.
• Ensure the bottom of the crack is clean and dry to promote adhesion.

Filling the Crack

• Select an appropriate asphalt crack filler, considering the type and size of the crack.
• Use professional equipment (asphalt crack filling machine)
• Fill the crack slightly above the surface to account for settling.

Compacting the Filler

Use a roller or heavy equipment to compress the crack filler, ensuring it adheres effectively.

4. Sealcoating

• After repairs are complete and have fully cured, apply a high-quality asphalt sealer to the entire driveway.
• Sealcoating provides a protective barrier against moisture, UV rays, and traffic wear.
