Asphalt Maintenance Facts
As soon as freshly laid hot asphalt pavement mix begins to cool, the aging process begins.
When oxygen in the air and water combine with asphaltic binder of the pavement, a chemical change takes place. At first, this process is necessary for the pavement to become hard and firm. Later, if this process is not arrested, a complete deterioration of the asphaltic binder will take place and reduce the pavement to a layer of loose stone.
Enemies of a parking lot include: gas, oil, sun oxidation, salt, water penetration, and hot or cold weather.
Protect Your Investment
In addition to routine inspections and ongoing maintenance, sealcoating asphalt pavement with a coal tar or asphalt-based emulsion slows pavement deterioration by protecting against the enemies of a parking lot. However, for maximum benefit, sealcoat needs to be applied approximately 12 months after the initial application and then on a regular basis, about every 24 to 48 months, thereafter.
