Whether you own an asphalt driveway, road, or parking lot, your asphalt represents a significant investment. Asphalt paving does cost significantly less than concrete, with a rate of around $2.50 - $4.00 per square foot, depending on the depth of the paving. However, it still represents a significant cost, as it is less durable than concrete. Below, you will find three reasons why you should consider sealcoating your asphalt to keep it in strong condition.
1. Asphalt Reacts to Petroleum Products
Because asphalt is usually used as a surface for vehicles, asphalt is often exposed to petroleum based products such as gasoline, oil, and other fluids. These fluids react with the petroleum-aggregate mixture that is asphalt, loosening the aggregate debris. This then leads to cracks, potholes, and further exposure.
To prevent this, a sealcoat, usually made from a plastic or acrylic mixture, creates a barrier against the oils and fuels let out of vehicles. This is especially important for parking lots, where vehicles sit and potentially leak for extended amounts of time.
2. Asphalt is Susceptible to Moisture
While not as prevalent an issue in warmer climates, moisture can devastate asphalt when it soaks into, freezes, and then thaws asphalt. When water finds its way into asphalt, it has the potential to freeze and expand. This expansion pushes and pulls on the asphalt, creating cracks and potholes. While not necessarily a problem when exposed to water once or twice, the regular thawing during the day under the sun and freezing at night can reduce the lifespan of asphalt by years.
Again, the sealcoat protects the asphalt with a barrier that repels moisture and liquid. If your asphalt is in a climate with high precipitation or has severe seasonal temperatures, sealcoating is essential to increasing the asphalt's lifespan.
3. Asphalt doesn't have Multiple Colors
While certainly not essential, giving color to asphalt can add aesthetic value to a property. Asphalt usually comes in a black or gray, but almost any color can be added with an acrylic sealcoat. Expensive venues, such as country clubs and golf courses, may want to color the sidewalks, parking lots, and roadways with the colors of the club, or may want to add custom designs and decorations.
These colorful coats add all the protection of a normal sealcoat with the added visual appeal that will impress those that visit the property.
