As summer temperatures rise and the sun beats down with relentless intensity, your asphalt driveway or parking lot takes the brunt of the heat. While asphalt is known for its durability, Colorado’s high-altitude sun and extreme temperature swings can accelerate wear and lead to visible signs of aging.
At Kauffman Seal Coating, we specialize in helping property owners in Glenwood Springs, Eagle, and throughout the Roaring Fork and Vail Valleys protect their asphalt surfaces with expert repair, sealing, and maintenance solutions.
How Summer Heat Affects Asphalt
- Softening and Rutting
During peak summer heat, asphalt can soften—especially under heavy vehicles or equipment. This can lead to surface depressions or “ruts,” especially in parking areas or high-use driveways. - Oxidation and UV Damage
The high-altitude sun in Colorado is no joke. UV rays accelerate the oxidation process, drying out the binding oils in your asphalt and causing it to become brittle, gray, and more prone to cracking. - Thermal Expansion and Cracking
Asphalt expands in the heat and contracts as temperatures drop at night. These constant shifts cause small cracks to form or worsen over time, especially if the surface is already showing signs of age or prior damage.
What to Watch For in Summer
If you have an asphalt driveway or parking lot, watch for:
- Cracks spreading or widening
- Faded, gray color (a sign of UV and oxidation damage)
- Soft or sticky surface texture during peak heat
- Surface warping under parked vehicles
Preventative Maintenance Tips
1. Inspect Regularly
Walk your pavement monthly and look for hairline cracks or soft areas. Catching damage early makes repairs easier and more affordable.
2. Seal Cracks Promptly
Even small cracks allow water to penetrate, leading to bigger issues down the line. We recommend professional crack sealing using hot rubberized filler that flexes with the pavement.
3. Apply a Fresh Sealcoat
Sealcoating is one of the best defenses against sun and weather. It protects against oxidation, moisture, and minor surface wear. At Kauffman Seal Coating, we use high-quality sealants made for Colorado’s altitude and UV exposure—recommended every 2–3 years for best results.
4. Minimize Heavy Loads
Avoid parking trailers, RVs, or other heavy vehicles on hot asphalt during peak heat hours. Prolonged pressure can create dents and structural damage when the surface is softened.
5. Ensure Proper Drainage
Standing water is the enemy of any asphalt surface. Check for clogged drains, uneven grading, or pooling water—especially after heavy summer storms.
When to Call the Pros
Some issues require professional evaluation, including:
- Alligator cracks (web-like patterns)
- Large potholes or structural failure
- Poor drainage or heaving
- Repeated cracking in the same areas
If you notice any of the above—or just want peace of mind—Kauffman Seal Coating is here to help.
