The Environmental Impact of Asphalt Coating and How to Minimize It

What is Asphalt Coating?

Asphalt coating, also known as seal coating, is a process of applying a protective layer of asphalt and other materials to a road or parking lot surface. It is typically used to extend the lifespan of an existing pavement surface and to maintain its quality.

The Environmental Impact of Asphalt Coating

While asphalt coating can be a beneficial maintenance procedure for roads and parking lots, it can also have negative impacts on the environment. One of the primary environmental concerns associated with asphalt coating is the release of volatile organic compounds (VOCs) into the atmosphere.

These VOCs are released during the application process, as the coating dries, and as it wears away over time. VOCs are known to contribute to the formation of ground-level ozone, which can negatively impact air quality and human health.

Ways to Minimize the Environmental Impact of Asphalt Coating

There are several ways to minimize the environmental impact of asphalt coating:

Choose a seal coat material with low VOC emissions. Look for products that meet or exceed national VOC emissions standards.

Apply the coating during cooler temperatures or during the evening when the sun is not as strong. This can help to prevent the release of VOCs.

Use a spray system to apply the coating, rather than a squeegee or other methods that may release more VOCs into the air.

Properly seal any unused coating containers or dispose of them properly, following all local and national regulations.

Alternatives to Asphalt Coating

In addition to taking steps to minimize the environmental impact of asphalt coating, there are also alternative solutions that can be used to maintain and extend the lifespan of pavement surfaces. One such alternative is the use of permeable pavement materials, which allow rainwater to filter through the pavement and recharge the groundwater supply instead of running off into storm drains.

Another alternative is the use of recycled pavement materials, which can help to reduce the amount of waste generated during the maintenance process and lessen the environmental impact of producing new pavement materials.

The Bottom Line

Asphalt coating can be an effective way to maintain an existing pavement surface, but it is important to take steps to minimize its environmental impact. By choosing low-VOC coating materials, applying the coating during cooler temperatures, and using alternative maintenance solutions, we can help to protect the environment while still ensuring the safety and quality of our roads and parking lots.
