The Science Behind Asphalt Oxidation and How Sealcoating Helps
Asphalt surfaces are essential components of urban infrastructure, especially in cities like Mississauga. However, over time, asphalt undergoes a natural aging process called oxidation, which can significantly reduce its lifespan. Understanding this process and how sealcoating can protect your pavement is crucial for maintaining durable, safe parking lots and roadways.
What is Asphalt Oxidation?
Asphalt oxidation is a chemical reaction where the asphalt binder in pavement reacts with oxygen in the air. This reaction causes the asphalt to harden, become brittle, and lose its natural flexibility. The oxidation process accelerates when exposed to UV rays, heat, and environmental pollutants, which are common in urban environments like Mississauga.
The Science Explained
At the molecular level, asphalt consists of hydrocarbons and oils that keep it pliable. When oxidation occurs, these oils evaporate or chemically change, causing the asphalt to stiffen. This leads to cracks, surface raveling, and ultimately, pavement failure if left untreated.
Factors Accelerating Asphalt Oxidation
Several environmental and mechanical factors contribute to the speed of oxidation:
- Sunlight (UV Radiation): Prolonged exposure breaks down the chemical bonds in asphalt.
- Heat: High temperatures increase the rate of oil evaporation.
- Water Infiltration: Water can wash away protective oils and seep into cracks, exacerbating damage.
- Traffic Load: Constant pressure and friction weaken the surface.
- Pollution: Chemicals and pollutants in urban air accelerate deterioration.
How Sealcoating Protects Asphalt
Sealcoating is a protective layer applied over asphalt surfaces to shield them from elements that cause oxidation. Capital Parking Lot Line Painting, a leading company in Mississauga, specializes in sealcoating services designed to extend pavement life and maintain its appearance.
