The benefits of sealcoating is substantial when compared to asphalt that withholds from using it, yet many people are confused as to what the purpose is of this liquid coater. The main concerns for pavement longevity is the harsh effects that weather conditions may create, chemical reactions that create oxidization, and adaptability of the material so that constant restoration is not necessary.
The harsh effects that different weather conditions have on asphalt is quite tremendous in retrospect to what one may originally believe. The changes in temperature and abrupt increases in precipitation can not only increase moisture containment in the asphalt that creates faster than usual oxidization but the added liquid can be retained in small cracks and when the freeze/thaw cycle occurs at a more frequent rate which initiates a faster deterioration without a layer of sealcoating added for protection. While it does not prevent oxidization, sealcoating does slow down both the oxidization process as well as the hardening process, thus keeping the asphalt in its neutral position. The continuous interaction with different chemicals cause withering and deterioration that is visible via brittle asphalt that cracks easily. Some of these chemicals are petroleum/oil, and with weight being added on weaker asphalt by continuous traffic the longevity of its lifespan decreases drastically.
Sealcoating helps to slow down all of these processes and coincidentally increase the amount of time between asphalt replacements. The liquid coating acts like a temporary shield that initially erodes away and keeps the strength of the original asphalt.
