Asphalt parking lots are vital to any commercial or residential property, providing convenient and durable surfaces for vehicles. However, weather conditions can significantly damage asphalt surfaces, causing long-term damage if not properly maintained. In Calgary, where seasonal weather shifts from extreme cold in the winter to high heat in the summer, asphalt parking lots face unique challenges throughout the year. Understanding how different weather conditions impact asphalt can help you, as a property owner, make informed decisions about regular maintenance and care.
How Seasonal Weather Can Affect Asphalt Parking Lots
Asphalt parking lots are built to withstand the elements, but the forces of nature, particularly temperature fluctuations and precipitation, can cause noticeable wear and tear over time. In this article, we’ll discuss how weather conditions during each season affect asphalt parking lots and the importance of maintaining these surfaces to prevent long-term damage:
Winter
Extreme Cold And Freezing Temperatures
During the winter months, sub-zero temperatures in Calgary can have a dramatic effect on asphalt pavement. Asphalt is a porous material, meaning that water can seep into small cracks and crevices on the surface. When temperatures drop, this water freezes, expanding in volume and creating more stress on the asphalt. As a result, you may begin to notice cracks or even potholes forming, which will only worsen as the cycle of freezing and thawing continues. Freezing temperatures also cause the asphalt to contract, making it more vulnerable to cracking.
Snow And Ice
Snow and ice accumulation are common problems and can affect asphalt parking lots every year. Snowplows and de-icing chemicals used to clear parking lots of snow can also contribute to the deterioration of asphalt surfaces. The constant scraping from snowplows can wear down the surface, and chemicals like salt, although effective for melting ice, can weaken the asphalt over time. As the ice melts and refreezes, it can further exacerbate existing cracks and damage.
Spring
Heavy Precipitation
As the snow begins to melt in the spring, parking lots can accumulate a lot of water. If the asphalt surface is already cracked or damaged, this water can seep deeper into the pavement, resulting in water infiltration. Excess moisture beneath the surface can weaken the foundation of the asphalt, resulting in the expansion of cracks or the formation of new ones. Over time, this can cause severe damage to the integrity of the parking lot, leading to costly repairs.
Thawing Snow
Spring brings unpredictable weather, including alternating freezing and thawing temperatures in areas like Calgary. This cycle, similar to the winter freeze-thaw process, can continue to cause damage to asphalt parking lots. As snow melts and refreezes, the expanding and contracting forces can widen cracks and cause the asphalt to settle unevenly. In some cases, this can result in the development of depressions or uneven surfaces, which can be both an eyesore and a safety concern.
Summer
Extreme Heat
During the summer months, asphalt parking lots face the opposite challenge—extreme heat. High temperatures can cause asphalt surfaces to soften, which may lead to ruts, indentations, and even cracking under the weight of heavy vehicles. The sun’s UV rays also break down the asphalt, causing the surface to fade and discolour. Over time, excessive heat can cause asphalt to deteriorate, resulting in a worn and tired appearance.
One often-overlooked issue in hot weather is the fading of parking lot line painting. The intense sun and heat can cause parking lot markings to fade, making it difficult for drivers to follow traffic patterns. To prevent this, you should consider parking lot line painting in Calgary as part of regular maintenance to ensure that the markings remain visible and clear. Regular re-striping is a simple way to improve both the aesthetics and safety of your parking lot.
Seeking Professional Asphalt Paving Services In Calgary
Regular maintenance is crucial to extending the lifespan of your asphalt parking lot, especially in Calgary’s harsh and unpredictable climate. Weather-related damage can cause cracks, potholes, and other issues, but proactive care—such as crack sealing, repaving, and regular inspections—can help you avoid costly repairs down the line.
Professional asphalt paving services are essential for ensuring your parking lot remains in optimal condition year-round.
To protect your asphalt from water infiltration, apply seal coating to prevent cracks and maintain proper drainage; doing this will help improve the surface’s durability and performance across all seasons.
Calgary’s extreme weather can take a heavy toll on parking lots, so it’s important to work with paving professionals who understand the specific challenges posed by the local climate. Experienced contractors can identify minor issues early on and address them before they turn into major problems. Treatments like seal coating and crack filling can significantly extend the life of your asphalt surface, keeping it safe and functional for longer.
For Calgary property owners, partnering with an experienced asphalt company ensures your parking lot stays in top shape throughout the year, whether you need sealing, repaving, or parking lot line painting. Regular professional maintenance is key to protecting your investment and maintaining the integrity of your parking lot despite the changing seasons.
