Comments: Regular cycles of seal coating (along with any needed repair) has proven to be the best program in our opinion for the long term care of asphalt pavement. The primary reason to seal coat asphalt pavement is to protect the pavement from the deteriorating effects of sun and water. When asphalt pavement is exposed, the asphalt oxidizes, or hardens which causes the pavement to become more brittle. As a result, the pavement will be more likely to crack because it is unable to bend and flex when subjected to traffic and temperature changes. A seal coat combats this situation by providing a water-resistant membrane, which not only slows down the oxidation process but also helps the pavement to shed water, preventing it from entering the base material. Seal coating also provides uniform appearance, concealing the inevitable patching and repairs which accumulate over time. Seal coating ultimately can extend the useful life of asphalt, postponing the need for asphalt resurfacing. If asphalt is already cracked, raveled and otherwise deteriorated, seal-coating will not provide much physical benefit, but still may have aesthetic benefits for curb appeal.
