Vancouver is known for its cloudy, grey skies and rainy weather so this year’s heatwave came as a surprise to everyone. With most homes being ill-prepared for temperatures of this magnitude, the heat has not only affected people and pets but also vegetation, cars and even driveway paving in Vancouver. But how will this blazing summer affect your driveway? Let’s take a look.
How Heats Affects Asphalt
Basically, every hard surface absorbs heat. This causes not only surface temperatures to rise, but also the temperature of the surroundings. This creates strong ambient heating which results in an environment that feels like a sauna. The area then becomes an urban heat island, a term given to a metropolitan area that is significantly warmer than its more rural surroundings due to a lack of vegetation an abundance of human activities. It can also occur from too many paved, dark or impermeable surfaces. Comparing a city centre adorned with cement buildings and glass skyscrapers with a cool forest with pristine air is where the difference lies.
Common Asphalt Issues Caused by Hot Summers
Heat makes asphalt brittle. It can cause it to soften, bruise pit and deform, especially when there are heavy loads on top of it.
Raveling: Raveling is deterioration that occurs due to a loss of aggregate (which consists of gravel, sand and crushed stone). It typically occurs in a downward motion. The major issue with raveling is that it exposes the layers beneath and leads to further deterioration.
Cracking: Cracking is incredibly common in asphalt and can happen due to extended exposure to heat. Although it’s more common in old surfaces, it can also affect newly paved driveways that weren’t installed properly or aren’t being well-maintained. It often affects places where heavy loads are a day-to-day occurrence like parking lots (especially outdoor parking lots), highways and you guessed it: driveways.
Oxidation: Oxidation takes place due to ultraviolet radiation from the sun’s strong rays. This chemical reaction weakens your driveway paving in Vancouver and causes the asphalt surface to become brittle. Overtime, this problem can worsen and lead to other costly issues.
Preventing Heat Damage
There are a few things you can do when it comes to preventing heat damage on your driveway.
- Sealcoat: One of the best things you can do for your driveway is to regularly sealcoat the surface. This will act as a protective top coat to your driveway, minimize the effects of harsh weather and keep it safe from uv rays.
- Shade: If possible, setting up a sort of sunshade atop your driveway will not only protect the asphalt surface but also your car when it’s time to park it.
- Water: Cooling your driveway down once a day by hosing it down or spraying it with cold water will prolong the life of your driveway.
