Various factors contribute to the formation of asphalt cracks, from environmental influences to structural issues. Recognizing these causes is key to preventing damage and prolonging the life of your asphalt. Below, we explore five common causes of asphalt cracks and how they impact your surface.

1. Weather and Temperature Fluctuations

Extreme weather conditions and temperature changes are leading contributors to asphalt cracks. Hot temperatures cause asphalt to expand, while cold temperatures cause it to contract. This constant cycle of expansion and contraction weakens the asphalt over time, leading to cracks.

2. Poor Installation or Subbase Issues

If asphalt is not properly installed or if the subbase (the layer beneath the asphalt) is unstable, the surface may crack prematurely. A weak or uneven subbase can cause the asphalt to settle unevenly, leading to stress fractures.

3. Heavy Traffic and Overloading

Asphalt surfaces are designed to handle specific loads. Excessive or heavy traffic, such as large trucks or machinery, can put too much pressure on the asphalt, causing it to crack.

4. Water Penetration

Water is one of the most damaging elements for asphalt. If water seeps into the surface and reaches the subbase, it can erode the foundation and cause cracks. This is particularly problematic during freeze-thaw cycles, where water freezes, expands, and widens existing cracks.

5. Aging and Oxidation

Over time, exposure to sunlight and air causes the asphalt binder to oxidize, making the surface brittle and prone to cracking. Aging asphalt naturally loses flexibility, which makes it more susceptible to stress and damage.

Preventing asphalt cracks begins with proactive maintenance and proper care. Regular sealcoating every 2-3 years provides a protective layer that shields asphalt from harmful UV rays, water, and chemicals, significantly reducing the risk of cracks. Proper installation is equally important; ensuring the subbase is stable and well-prepared creates a strong foundation that prevents premature damage. Managing traffic loads and improving drainage systems also play key roles, as overloading and standing water can weaken the asphalt over time. Lastly, routine inspections, timely crack repairs, and consistent cleaning help address minor issues before they escalate, ensuring a long-lasting, durable asphalt surface.

Cracks in asphalt not only affect its appearance but also create safety hazards and reduce its structural integrity. If left untreated, cracks can worsen over time, leading to costly repairs or even full replacement. Proactive prevention and maintenance are key to preserving your asphalt and avoiding unnecessary expenses.
