Why Do Asphalt Cracks Form?
Understanding the root causes of pavement cracking helps highlight why timely repairs are so essential. Here are the most common contributors:
- Weather conditions: Water intrusion, freeze-thaw cycles, and intense UV exposure all break down asphalt binders. As seasons shift, moisture enters small voids, expands when frozen, and worsens the damage.
- Heavy traffic loads: Parking lots, loading zones, and service areas bear the brunt of daily vehicle weight. Repeated stress over time causes the surface to fatigue and fracture—especially where traffic is concentrated—prompting the need for parking lot crack filling services.
- Aging asphalt: Like any material, asphalt deteriorates with age. The binders that hold aggregate together oxidize and become brittle, making the pavement more susceptible to cracking even under normal conditions.
- Improper installation or lack of maintenance: If the base wasn’t properly compacted or sealcoating was delayed, the asphalt will degrade faster. Routine parking lot maintenance is key to preventing early damage.
