Marty’s Seal Coating has spent more than three decades helping homeowners and businesses across Western New York protect and preserve their asphalt surfaces. One of the questions we hear most often is, “Why does my asphalt crack?” While asphalt is a durable material, it’s still vulnerable to several environmental and structural stressors. Understanding what causes cracking is the first step in preventing and maintaining a surface that lasts.
Weather and Temperature Extremes
Here in Western New York, our climate plays a major role in asphalt deterioration. Asphalt naturally expands in heat and contracts in cold temperatures. Over time, these repeated freeze-thaw cycles create stress that leads to surface cracks. Moisture is another significant factor. When water seeps into small openings, it can freeze, expand, and widen those cracks. This is why routine maintenance and sealcoating services are so important for protecting your driveway or parking lot from seasonal damage.
Oxidation and Sun Exposure
UV rays may not seem as harsh as snow or ice, but they can be just as damaging. Prolonged sun exposure causes asphalt to oxidize turning it from deep black to faded gray. As it oxidizes, the binder holding the aggregates together becomes brittle, which makes the surface more prone to cracking. This process happens slowly and often goes unnoticed until visible damage appears. By applying a high-quality, brush-on sealcoat every 2–3 years, we help restore flexibility to the surface and shield it from further UV breakdown.
Traffic and Structural Stress
Every vehicle that drives across your asphalt puts pressure on it. Over time, this stress can lead to fatigue cracking, which spreads across the surface in a web-like pattern. Heavy commercial vehicles, unsupported edges, or weak base layers beneath the asphalt can accelerate the process. Even oil and gasoline leaks can soften the pavement and make it more vulnerable. That’s why regular cleaning, crack filling, and professional maintenance will help keep your surface strong.
Protect Your Investment with Professional Sealcoating
Cracks may be common, but they’re far from inevitable. With regular care, such as hot rubberized crack filling and our brush-applied Masterseal coating, you can significantly extend the life of your driveway or parking lot.
