Weather isn’t just a seasonal inconvenience; it’s a culprit behind many expensive asphalt issues. Cracks, erosion, faded surfaces, and potholes are often the direct result of prolonged exposure to the elements. If small problems go ignored, they can worsen over time and cost you thousands. Protecting your parking lot isn’t an option. It’s a necessity. Here’s everything you need to know about how weather impacts asphalt and how to maintain your investment.
How Weather Conditions Affect Asphalt
Damage from Heat and Sunlight
Parking lots are exposed to the sun’s UV rays daily, and prolonged heat can wreak havoc on asphalt surfaces. High temperatures cause asphalt to expand, weakening its structure over time. In fact, research suggests that UV rays can accelerate the aging of asphalt pavements by up to 50%. UV exposure can also oxidize the bitumen (binding agent), leading to faded colors and brittle surfaces that crack more easily. If left unchecked, these issues can impact the stability and visual appeal of the pavement, requiring costly repairs.
The Erosive Effect of Rain
Rain might seem harmless, but it’s one of the most damaging weather phenomena for asphalt. Heavy rain can penetrate the surface, compromising the subbase layers and leading to potholes or sinkholes. Additionally, standing water after storms can increase the risk of long-term cracking and erosion. Without proper drainage systems, the cumulative damage from rainwater can reduce the lifespan of your parking lot.
Freeze-Thaw Cycles
For regions that experience colder weather, the freeze-thaw cycle presents an ongoing challenge. When water seeps into cracks in the asphalt and freezes, it expands and forces the pavement apart. Once the ice melts, the gaps remain wider, leading to permanent cracks, rutting, and uneven surfaces. If not addressed promptly, this process repeats itself and large-scale damage can occur.
Winter Hazards: Snow and Ice
Snow and ice harm parking lots in many of the same ways rain and freeze-thaw cycles do. Additionally, snow removal equipment and tools like plows may scrape or chip away at the asphalt surface. De-icing agents such as salt can also corrode pavement materials and lead to quicker deterioration during the winter months.
How to Prolong the Lifespan of Your Parking Lot
Protecting your parking lot begins with regular maintenance and proactive steps to minimize weather damage. Here are some proven strategies:
Sealcoating to Prevent Damage
Sealcoating your parking lot creates a protective barrier against UV rays, rainwater, freeze-thaw cycles, and more. For instance, 85% less water is absorbed by using sealcoating. This cost-effective solution helps preserve the smoothness and appearance of your asphalt. It also minimizes oxidation and delays cracking, ensuring your lot stays strong under all weather conditions.
Routine Cleaning
Cleaning your parking lot regularly can prevent long-term damage due to debris, dirt, standing water, or oil spills. These impurities can degrade your asphalt faster, especially when combined with weather-related problems.
Fix Cracks and Potholes Immediately
Addressing small cracks and potholes promptly is crucial to preventing larger deterioration. Use professional asphalt repair services like those offered by Line Pro Inc. to minimize damage before it spreads.
Invest in Proper Drainage
Having an adequate drainage system ensures rainwater doesn’t pool on the surface. Clogged drains, poor sloping, or faulty installation can lead to standing water issues that severely damage your asphalt over time.
