Applying a protective coating to asphalt pavement is a necessary preventive maintenance strategy to protect your investment against damage from the elements, oil and U.V rays, all of which can cause severe cracks and costly repairs. We highly recommend getting your driveway, parking lot, tennis court, footpath, or other asphalt surface coated. Not only will sealcoating protect your asphalt surface, it will also enhance its appearance.

Why does asphalt need sealcoating?

Asphalt is a complex mixture of thousands of chemicals with a predominantly open-chain molecular structure and a considerable degree of un-saturation. These “open-chains” mean that asphalt is quite porous and prone to infiltration by:

Infiltration causes asphaltic molecules to disintegrate. This results in the pavement losing much of its original properties, such as binding and waterproofing. 

What are the different types of sealer?

There are two primary types of sealcoating materials used on the market today: those made from refined coal tar and those made from asphalt. Refined coal tar is a byproduct in the coking process in the steel industry. Coal tar sealers were introduced in the 1950’s and have been used primarily to protect off-street pavement surfaces.

Asphalt base sealers have become very popular in recent years due to coal tar shortages, but asphalt emulsions resistance to petrochemicals and solvents has yet to be overcome. Asphalt emulsions are more user friendly, practically odorless and do not irritate or burn the skin, but just do not hold up as well over time. In many applications asphalt base sealers have problems bonding to the polished stone in asphalt after the first winter. In late season applications with asphalt base sealer, it often looks like the asphalt was not even sealed.

Asphalt Deterioration – Know the Signs

The first sign of breakdown is the asphalt's color changing from black to gray. The asphalt turns gray as it starts to release the asphalt binder which holds it to the base. The base begins to deteriorate at this stage and without attention the deterioration will reach the surface within a year.

Once there is deterioration at the surface, minor cracks will start to develop. These cracks will widen and deepen over time. If the cracks are not repaired at this stage, water will seep into the base and damage the pavement’s load bearing capacity and structural integrity. This will be evident by rutting, shifting, and “alligatoring.”

At this point, the asphalt usually needs to be overlaid or undergo complete asphalt removal and reinstallation. During replacement, a protective coating is applied that resists attack by the elements that destroy asphalt in the first place.
