The Science Behind Asphalt Oxidation and How Sealcoating Helps
Asphalt pavements are a common feature in cities like Ottawa, providing durable surfaces for roads and parking lots. However, over time, asphalt undergoes oxidation, which compromises its integrity and appearance. Understanding this process and how sealcoating can protect your pavement is essential for maintaining long-lasting surfaces.
What is Asphalt Oxidation?
Asphalt oxidation is a chemical reaction between the asphalt binder and oxygen in the air. This process causes the asphalt to harden and become brittle over time, leading to cracks, surface deterioration, and a faded appearance. Oxidation is accelerated by exposure to sunlight, heat, and environmental pollutants.
Chemical Changes During Oxidation
During oxidation, the oils in the asphalt binder evaporate or chemically react with oxygen molecules, causing the binder to lose its flexibility. This loss of flexibility reduces the pavement’s ability to withstand stress from traffic loads and temperature changes.
Why is Oxidation a Concern for Ottawa Pavements?
Ottawa, as a top 30 city in Ontario, experiences a variety of weather conditions including hot summers and harsh winters. These seasonal fluctuations exacerbate the oxidation process. Freeze-thaw cycles cause the brittle asphalt to crack, allowing water to penetrate and further damage the pavement structure.
Maintaining asphalt pavements in Ottawa requires proactive measures to combat oxidation and extend the lifespan of surfaces such as parking lots and roads.
How Sealcoating Protects Asphalt
Sealcoating is a protective application applied to asphalt surfaces to shield them from the harmful effects of oxidation. It forms a barrier that prevents oxygen, water, and UV rays from penetrating the pavement.
Key Benefits of Sealcoating
- Prevents Oxidation: Slows down the chemical aging of the asphalt binder by limiting oxygen exposure.
- Waterproofing: Reduces water infiltration which can cause freeze-thaw damage.
- Improved Appearance: Restores the black color and gives a fresh, clean look to asphalt surfaces.
- Extends Pavement Life: Delays the need for costly repairs and resurfacing.
- Cost-Effective Maintenance: A simple preventive step that saves money in the long run.
