Asphalt paving is extremely durable and can withstand many weather conditions. However, that doesn't mean that your parking lot is impenetrable. Excessive rainfall, for instance, can do serious damage if the surface isn't properly maintained or repaired right away. Here's a closer look at how the moisture can harm your parking lot and how to protect the surface.
How Does Rain Affect an Asphalt Surface?
Cracks in the surface of your parking lot allow rain to penetrate the asphalt paving. Once it does, it weakens the bond that holds the binder and the aggregate materials together, resulting in erosion and a gradual deterioration of the asphalt layers.
If the rainfall occurs closer to the fall or winter months, there's also the possibility of freezing, which worsens the potential for damage. After water penetrates surface cracks, it will freeze and expand. When the ice melts, it will leave behind bigger cracks, dips, and potholes.
How Can You Prevent Rain Damage?
Sealcoat is a mixture of liquids and small particles applied to asphalt paving for protection. It essentially forms a seal, creating a layer that shields the surface from water, oil, and sun damage. When a parking lot is sealcoated properly, water has fewer opportunities to seep into the surface and wreak havoc.
You can also prevent damage by keeping up with asphalt maintenance. Inspect the surface regularly and have all cracks repaired as soon as possible. Always practice caution when using sharp tools, shovels, or heavy machinery on your asphalt surface to avoid making cracks for water to enter.
The parking lot should also have an effective drainage system in place. If the lot doesn't already have them, consider installing grates and catch basins or storm drains to carry excess water away from the asphalt.
