Paved surfaces, including driveways, parking lots, and sidewalks, allow employees and customers to navigate your business property with ease. However, over time, you may notice cracks in the asphalt that diminish the appearance of outdoor areas, present safety hazards, and potentially cause property damages. Here are some of the most common causes of cracking and how to repair or prevent them.

Why Do Cracks Form in Asphalt Surfaces?

1. Freeze-Thaw Cycle

During the winter months, it's common for precipitation to freeze after collecting on your pavement. However, when moisture seeps into small crevices and then freezes, it'll expand and cause the concrete to shift and crack. When the ice thaws and refreezes in the same fissure, it'll spread and lengthen. In this scenario, crack filling with coal tar and emulsions can mitigate the damage.

2. Standing Water

When water pools onto your asphalt and remains for long periods, it'll seep into small openings and contribute to softening, displacement, and cracking. Improve drainage near driveways and sidewalks by installing channel or trench drains to divert moisture from the pavement.

3. Temperature Fluctuations

High outdoor temperatures cause asphalt to soften, making it more susceptible to sloughing and warping beneath heavy vehicles. Avoid this by parking your trucks in different spots during the summer to prevent excess weight from bruising or pitting the pavement.

4. Chemical Exposure

Petroleum and diesel often leak beneath vehicles and stain asphalt. Though they may seem like cosmetic issues, these chemicals corrode and weaken the surface, making it more vulnerable to cracking under weight and pressure. If you notice oil leaks, sop them up with cat litter before sweeping them up and discarding them.
