Even the best pavement will crack and deteriorate after time. But there are ways in which you can extend the life of your pavement. One of these ways, as this article from PaveManPro.com explains, is Pavement Sealer.

Asphalt hardening is an oxidation process and is a function of its exposure to air on the surface and within the pavement. If circulation of air through the interconnected void spaces in the pavement can be prevented or reduced, the rate of hardening of the asphalt will be slowed and the life of the pavement extended. Pavement sealers are used to do just that – close the surface pores to lengthen the life of the pavement.

Pavement sealers come in two basic formulas: Refined Tar-Based Sealer and Asphalt Based Emulsions.

Refined Tar-Based Sealer

Refined tar is a by-product of the distillation of crude coal tar. Refined tar differs from crude coal tar in that during the distillation process, the lighter end oils are removed from the refined tar. Refined tar based sealer is resistant to attack from petroleum based products. This property makes it ideally suited for parking lots or other locations where concentrations of oil and grease leaks are common. Refined tar-based sealer is also highly resistant to ultraviolet light bleaching. It is stable, homogeneous, easy to apply, and has been handled safely by professionals and do-it-yourselfers for decades. Refined tar based sealer has traditionally been used at gas stations, truck and bus terminals, airport aprons and taxiways as well as on residential driveways and commercial parking lots.

Asphalt based emulsions

Asphalt-based emulsions have many of the same beneficial properties as refined tar- based emulsions, but they are less resistant to corrosion by petroleum-based products, ultraviolet bleaching, and salts. An asphalt emulsion is a mixture of liquid asphalt and water. Manufacturers add special chemicals and pigments to the asphalt emulsions to improve performance but they remain susceptible to the damage caused by petroleum products.

Pavement sealers allow homeowners and businesses to maintain their asphalt effectively and economically. Research has shown that when asphalt pavement is maintained properly, the owner can extend the life of their pavement and delay costly reconstruction.
