Safeguard Your Investment

Asphalt surfaces, whether driveways, parking lots, or roadways, are designed to be durable and long-lasting. However, without proper maintenance, they can deteriorate over time due to various environmental and physical factors. At Salisbury Pro Sealers, we specialize in helping property owners protect their asphalt investments through expert sealcoating and maintenance services. In this article, we will explore the most common causes of asphalt damage and the best ways to prevent costly repairs.

1. Water Penetration and Freeze-Thaw Cycles

One of the leading causes of asphalt deterioration is water infiltration. When water seeps into cracks and small openings, it can undermine the structural integrity of the pavement. This becomes especially problematic in colder climates, where freeze-thaw cycles cause water to expand and contract, leading to larger cracks, potholes, and surface breakage.

Prevention Tips:

• Sealcoat regularly: Applying a high-quality sealcoat forms a protective barrier that prevents water from penetrating the surface.
• Fill cracks promptly: Even small cracks should be sealed to prevent water from seeping in and causing larger structural issues.
• Ensure proper drainage: Make sure that water is directed away from the asphalt with adequate slope and functioning drainage systems.

2. UV Ray Exposure and Oxidation

Asphalt surfaces are constantly exposed to the sun’s UV rays, which can dry out essential oils in the pavement. This leads to oxidation, causing the asphalt to become brittle and lose its flexibility. Over time, this makes the surface more susceptible to cracking and raveling.

Prevention Tips:

• Apply a UV-resistant sealcoat: A fresh layer of sealcoat every few years helps protect asphalt from sun damage and slows oxidation.
• Use high-quality materials: When installing or resurfacing asphalt, using materials with anti-oxidation additives can extend its lifespan.
• Regular inspections: Property owners should schedule annual inspections to identify signs of oxidation before they lead to major damage.
  

3. Heavy Traffic Loads and Excessive Weight

Asphalt is designed to support vehicle traffic, but excessive or unevenly distributed weight can lead to premature wear and deep rutting. Large commercial trucks, delivery vehicles, and improperly parked heavy equipment can cause cracks, depressions, and structural breakdown.

Prevention Tips:

• Use reinforced asphalt for high-traffic areas: If your asphalt surface is used by heavy vehicles, opt for a thicker layer with a strong base.
• Redirect traffic flow: Designate weight restrictions or alternate routes for heavy loads to prevent excessive stress on one area.
• Repair depressions early: If you notice tire ruts or sunken areas, address them quickly before they turn into major cracks.
  

4. Poor Installation and Base Preparation

The longevity of an asphalt surface depends heavily on the quality of its installation. If the sub-base is not properly compacted or if low-quality materials are used, premature cracking and surface failures are likely.

Prevention Tips:

• Hire experienced professionals: Choose a reputable asphalt contractor like Salisbury Pro Sealers for installation and resurfacing projects.
• Ensure proper compaction: The sub-base must be well-compacted to provide stability and support.
• Choose the right asphalt mix: Not all asphalt is created equal—select the appropriate mix for your specific climate and traffic conditions.
  

5. Oil and Chemical Spills

Oil, gasoline, and other automotive fluids can break down asphalt’s binding agents, leading to soft spots, surface deterioration, and potholes. Spills from parked cars or industrial equipment are common causes of localized asphalt damage.

Prevention Tips:

• Clean spills immediately: If a spill occurs, clean it with absorbent materials and mild detergent before it penetrates the surface.
• Use sealcoating as a protective barrier: A properly sealed asphalt surface is more resistant to chemical damage.
• Regularly inspect high-risk areas: Parking lots, loading docks, and drive-through lanes should be checked frequently for spills.
  

6. Tree Roots and Vegetation Growth

Tree roots naturally seek out moisture and can grow underneath asphalt surfaces, causing cracking and upheaval. Weeds and grass growing through cracks can further widen gaps and allow more water penetration.



Prevention Tips:

• Trim tree roots proactively: When planting trees near asphalt, use root barriers or select species with non-invasive root systems.
• Remove weeds from cracks: Apply herbicide or manually remove vegetation before it causes further damage.
• Fill cracks with a durable sealant: Proper crack filling prevents root expansion and stops weeds from sprouting.
  

7. Lack of Regular Maintenance

One of the biggest contributors to asphalt deterioration is simply neglect. Small issues that go unaddressed can quickly become major problems, leading to expensive repairs or even full resurfacing.

Prevention Tips:

• Schedule routine inspections: Have your asphalt assessed by professionals at least once a year.
• Invest in preventative maintenance: Crack sealing, sealcoating, and minor repairs can significantly extend the lifespan of your pavement.
• Follow a maintenance plan: Establish a long-term asphalt care strategy based on your usage and environmental conditions.
