Q: How do I know which type of asphalt repair I need?

The type of repair needed depends on the specific damage to your asphalt surface: For linear cracks less than 1/2 inch wide, crack filling or sealing is appropriate. For isolated holes or depressions, pothole patching is needed. For interconnected cracks resembling alligator skin, you likely need section removal and replacement. For crumbling edges, edge repair with proper support is necessary. For widespread damage covering more than 25-30% of the surface, consider resurfacing instead of multiple repairs.

Q: What's the difference between crack filling and crack sealing?

While often used interchangeably, crack filling and crack sealing are different processes. Crack Filling is used for non-working cracks (cracks that don't expand and contract significantly), typically uses asphalt emulsion or liquid asphalt, is less expensive but generally has a shorter lifespan (2-3 years), requires minimal preparation, and is good for dormant, non-structural cracks. Crack Sealing is used for working cracks (those that expand and contract with temperature changes), uses specialized rubberized materials with high elasticity, is more expensive but longer-lasting (3-5+ years), requires more thorough preparation including routing the crack, and is better for structural or active cracks.

Q: How long do asphalt repairs typically last?

The lifespan of asphalt repairs varies based on several factors. Different repair types have different lifespans: Crack filling: 2-3 years, Crack sealing: 3-5 years, Pothole patching: 2-5 years, Alligator cracking repair: 3-7 years, Edge repair: 3-5 years, Full-depth patching: 7-15 years. Factors affecting longevity include quality of materials used, proper preparation and installation, traffic volume and type, climate conditions, drainage conditions, and ongoing maintenance. Professional repairs typically last longer than DIY repairs due to better materials, equipment, and techniques.

Q: What's the best time of year for asphalt repairs?

The ideal time for asphalt repairs is during warm, dry weather with temperatures consistently between 50°F and 90°F (10°C and 32°C). In most regions, late spring through early fall provides the best conditions. Specific considerations include temperature (asphalt repair materials need warm temperatures to cure properly), precipitation (no rain should be forecasted for at least 24-48 hours after repairs), seasonal timing (spring is often ideal for repairing winter damage before summer heat), and ground conditions (the base should be dry, not frozen or saturated).

Q: Should I repair or replace my asphalt surface?

The decision between repair and replacement depends on several factors. Consider repairs when damage is limited to less than 25-30% of the total surface, the asphalt is less than 15-20 years old, the base is solid with no significant structural issues, budget constraints make replacement unfeasible, and the damage is primarily surface-level. Consider replacement when damage covers more than 30-35% of the surface, the asphalt is more than 20-25 years old, there are significant base or drainage issues, multiple repairs have already been made, and extensive alligator cracking indicates base failure.

Q: What causes asphalt damage and how can I prevent it?

Asphalt damage is caused by several factors: water infiltration (the #1 enemy of asphalt), freeze-thaw cycles, UV radiation, heavy loads, oil and chemical spills, poor installation, tree roots, and age-related deterioration. Prevention strategies include applying sealcoating every 2-3 years, filling cracks promptly, maintaining proper drainage, cleaning up spills immediately, avoiding parking in the same spot repeatedly, distributing heavy loads, considering root barriers for trees near asphalt, and avoiding deicing chemicals that can damage asphalt. Regular maintenance is the key to preventing major damage.

What's the difference between crack filling and crack sealing?

While often used interchangeably, crack filling and crack sealing are different processes:

Crack Filling:
• Used for non-working cracks (cracks that don't expand and contract significantly)
• Typically uses asphalt emulsion, liquid asphalt, or similar materials
• Less expensive but generally shorter lifespan (2-3 years)
• Minimal preparation required
• Good for dormant, non-structural cracks

Crack Sealing:
• Used for working cracks (those that expand and contract with temperature changes)
• Uses specialized rubberized materials with high elasticity
• More expensive but longer-lasting (3-5+ years)
• Requires more thorough preparation, including routing (widening) the crack
• Better for structural or active cracks

For optimal results, working cracks should be properly sealed rather than filled, while non-working cracks can be effectively treated with filling.

How long do asphalt repairs typically last?

The lifespan of asphalt repairs varies based on several factors:

Repair Type:
• Crack filling: 2-3 years
• Crack sealing: 3-5 years
• Pothole patching: 2-5 years
• Alligator cracking repair: 3-7 years
• Edge repair: 3-5 years
• Full-depth patching: 7-15 years

Factors Affecting Longevity:
• Quality of materials used
• Proper preparation and installation
• Traffic volume and type
• Climate conditions (freeze-thaw cycles, extreme heat)
• Drainage conditions
• Ongoing maintenance (sealcoating, cleaning)

Professional repairs typically last longer than DIY repairs due to better materials, equipment, and techniques. Regular maintenance, particularly sealcoating every 2-3 years, can significantly extend the life of repairs.

What's the best time of year for asphalt repairs?

The ideal time for asphalt repairs is during warm, dry weather with temperatures consistently between 50°F and 90°F (10°C and 32°C). In most regions, late spring through early fall provides the best conditions. Specific considerations include:

• Temperature: Asphalt repair materials need warm temperatures to cure properly

For emergency repairs during cold weather, special cold-weather patching materials are available, though these may not be as durable as repairs done in optimal conditions.

Should I repair or replace my asphalt surface?

The decision between repair and replacement depends on several factors:

Consider Repairs When:
• Damage is limited to less than 25-30% of the total surface
• The asphalt is less than 15-20 years old
• The base is solid with no significant structural issues
• Budget constraints make replacement unfeasible
• The damage is primarily surface-level

Consider Replacement When:
• Damage covers more than 30-35% of the surface
• The asphalt is more than 20-25 years old
• There are significant base or drainage issues
• Multiple repairs have already been made
• Extensive alligator cracking indicates base failure

A third option is resurfacing (overlay), which involves adding a new layer of asphalt over the existing surface. This is a good middle ground when the base is sound but the surface has extensive damage.

For the most accurate assessment, consult with multiple asphalt contractors who can evaluate your specific situation.

What causes asphalt damage and how can I prevent it?
