Essential Tips for Proper Asphalt Repair and Maintenance

Asphalt pavements are built to last, but time, weather, and traffic wear them down. Without proper maintenance, issues like cracks, potholes, and surface degradation can lead to costly repairs. At Regal Paving, we specialize in maintenance services that protect and extend the lifespan of your asphalt infrastructure. This guide will walk you through the key preservation methods that every property owner should understand.

What Causes Asphalt Deterioration?

Asphalt surfaces face constant stress from environmental and mechanical forces. Common causes of deterioration include:

• Moisture Penetration: Water infiltrates cracks, weakening the sublayers.

• Oxidation: UV rays cause asphalt to harden and become brittle.

• Traffic Stress: Heavy loads and repetitive motion contribute to fatigue cracking.

• Poor Drainage: Standing water accelerates wear and tear by compromising the base layer.

Over time, these factors result in cracking, raveling, and pothole formation, reducing the pavement’s structural integrity.

Seal Coating: Protecting the Surface Layer

Seal coating involves applying a protective asphalt emulsion over the pavement. This layer prevents oxidation, seals out moisture, and improves the surface's appearance and traction. It is one of the most widely used maintenance techniques, especially for high-traffic areas. State Departments of Transportation (DOTs) commonly apply seal coating to maintain roads, providing protection that typically lasts 5 to 7 years.

Benefits of Seal Coating

• Creates a barrier against water and UV rays

• Restores skid resistance and surface texture

• Enhances the visual appeal with a fresh, dark finish

• Reduces long-term repair costs by delaying surface deterioration

However, seal coating is not a cure-all. While it protects the surface, it cannot resolve structural issues like deep cracks, rutting, or base failure.

Crack Treatments: A Critical First Line of Defense

Cracks provide a direct path for water to enter and damage the pavement's base layers. Without timely intervention, small cracks can expand and worsen due to temperature fluctuations and traffic. Crack treatments are categorized into two main methods:

1. Crack Sealing

This method is used for "working" cracks—those that expand and contract with temperature changes. Sealants are designed to remain flexible and adhere to the crack walls, preventing water infiltration and future damage.

Key Features:

• Requires thorough crack cleaning and preparation

• Ideal for transverse and reflective cracks

• Often involves routing (cutting) the crack to improve sealant adhesion

2. Crack Filling

Used for "non-working" cracks with minimal movement, crack filling involves less extensive preparation and shorter-term materials. It helps maintain the surface until further maintenance can be scheduled.

Patching: Repairing Localized Damage

Patching is essential for addressing potholes, edge damage, and other pavement failures. There are various methods based on the severity and type of damage:

Pothole Repair

Potholes form when water infiltrates the pavement and weakens the base. Quick repairs prevent further damage and ensure safety.

Dig-Out Patches

For more extensive damage, dig-out patches involve removing the damaged pavement and replacing it with new asphalt. This method restores structural integrity and prevents future failures.

Edge Patches

Edges are particularly vulnerable to cracking and collapse. Edge patches reinforce the pavement boundary, improving durability in areas prone to erosion or lateral pressure.

Preparing for Resurfacing

When resurfacing is needed, preparation is crucial for a successful project. Here are key steps:

1. Crack Treatments and Patching: To stabilize the foundation and prevent reflective cracking.

2. Sweeping and Edge Milling: To create a clean, smooth surface for the new asphalt layer.

3. Tack Coats: Applied between layers to improve bonding and prevent slippage.

Proper preparation ensures that the resurfacing adheres well and provides a long-lasting, high-quality finish.

How Maintenance Extends Pavement Life

Studies have shown that preventative maintenance can extend pavement life by up to 25%. By addressing minor issues early, you avoid costly full-depth repairs and keep your surfaces safe and functional. Regular maintenance—combined with good design and drainage—also reduces liability risks associated with damaged or uneven pavements.

Common Problems and How We Solve Them

At Regal Paving, we understand the challenges that come with asphalt maintenance. Here are some typical issues and our solutions:

Issue	Cause	Solution
