Sealers protect asphalt from petroleum spills of fuel, oil and solvents, which attack the pavement and seep deep beneath the surface, softening the asphalt and reducing adhesion. They also protect against sun and rain, which causes oxidation that can lead to raveling, cracks and even potholes.
Unlike parking lots and driveways, highways are constantly re-compacted by continuous traffic. Further, highways are not subject to the continuous attack of petroleum derivatives in specific spots or patterns as in parking stalls.
Sealer is made of a blend of high-grade ball clays, water, refined coal tar and proprietary emulsifier milled into a coal tar emulsion to generate a coating which insulates the petroleum-based asphalt from potential petroleum spillage and reduces the normal aging cycle of the asphalt, due to oxidation caused by sun light.
Depending on the weather and traffic conditions, it is recommended that asphalt be sealed every three to five years. With periodic maintenance, your pavement will last for many years. Without sealing, your pavement life may be only seven to twelve years. Seal coating is a fraction of the cost of repaving.
Depending on the current condition of your pavement, there may be a need to fill cracks, dig out soft spots damaged by petroleum spills, fill in potholes and generally patch the pavement with hot asphalt. Usually a recommended one to two coats of sealer will save you from costly repaving.
