Asphalt is a durable and cost-effective paving material, but over time, it undergoes wear and tear from traffic, weather conditions, and exposure to chemicals. One of the best ways to maintain your asphalt driveway or parking lot is through sealcoating, which protects the surface from damage and extends its lifespan. However, knowing when to reseal your asphalt is key to avoiding costly repairs. Today, we at Andersen Asphalt & Striping would like to discuss the top signs that indicate it’s time for a fresh sealcoat.
Fading Color
Freshly paved asphalt has a deep black color, but over time, exposure to the sun’s UV rays causes oxidation, leading to a dull gray appearance. This fading is more than just a cosmetic issue—it’s a sign that the asphalt is losing essential oils and becoming brittle. Resealing restores the surface’s rich black color while protecting it from further sun damage.
Small Cracks Forming
Hairline cracks are one of the earliest signs that your asphalt needs resealing. These cracks occur due to temperature fluctuations, moisture penetration, and regular wear. If left untreated, they can widen into larger cracks, eventually leading to potholes. Sealcoating fills in minor cracks and prevents water from seeping in, reducing the risk of more serious damage.
Potholes or Surface Depressions
Potholes form when cracks allow water to penetrate the asphalt, weakening its base. As vehicles pass over the weakened areas, chunks of asphalt break loose, forming potholes. While sealcoating won’t repair existing potholes, it can prevent new ones from forming by protecting the surface from water damage. If you notice potholes, have them repaired first, then apply a sealcoat to prevent further deterioration.
Water Pooling on the Surface
Properly sealed asphalt repels water, ensuring that it drains away efficiently. However, if you notice water pooling in certain areas after rain, it may indicate that the sealcoat has worn off. Standing water can quickly erode asphalt, leading to cracks and potholes. Resealing the surface helps restore its water-resistant properties and prevents future damage.
Rough or Uneven Texture
Asphalt should have a smooth, even surface. If you start noticing a rough, grainy, or pitted texture, it’s likely that the top protective layer has worn away. This deterioration leaves the asphalt vulnerable to further damage from vehicle traffic, weather, and chemicals. Sealcoating smooths out minor imperfections and restores the pavement’s protective barrier.
Oil & Chemical Stains
Vehicle fluids like oil, gasoline, and antifreeze can break down asphalt over time, leading to soft spots and weak areas. If your pavement has multiple oil stains that have seeped into the surface, it may be time to reseal. Sealcoating provides a protective layer that resists chemicals and makes future spills easier to clean.
Frequent Repairs Are Needed
If you find yourself frequently patching cracks or filling in small holes, it may be a sign that your asphalt is deteriorating faster than expected. Instead of continuously repairing small areas, a full reseal can provide a more cost-effective and long-lasting solution.
