Hi-Lite's Techniques for Making Pavements Last
Asphalt Pavement Rejuvenation - RejuvaSeal®
Once it has penetrated, RejuvaSeal dramatically reduces the viscosity and brittleness in the top one-half inch of asphalt while significantly increasing ductility and flexibility.
In addition to its ability to rejuvenate, RejuvaSeal is a very effective sealer. The capability to penetrate gives RejuvaSeal unique sealing characteristics. Asphalt surfaces treated with RejuvaSeal are fuel, water, and chemical resistant.
RejuvaSeal is durable. During thermal cycles, RejuvaSeal contracts and expands at the same rate as the asphalt. In comparison, coal-tar emulsions and other seal coats simply lay on the surface. They undergo a markedly differing expansion and contraction rate from the asphalt. This eventually leads to cracking, pin-holing, and delaminating. RejuvaSeal does not suffer from these problems; through penetration, it becomes an integral part of the asphalt.
RejuvaSeal should be applied to pavements before they begin to show the deleterious signs of age. The sooner the aging process is arrested, the easier and less expensive it will be to maintain the pavement. Application of RejuvaSeal® every four to five years will not only extend the life of the asphalt pavement indefinitely, but can reduce the life-cycle cost by sixty-seven percent or more.
Asphalt pavements, left unprotected, will be damaged and eventually destroyed by the effects of thermal and UV induced oxidation, erosion caused by moisture, gasoline and oil drippings, salt and chemicals. Coal tar emulsion pavement sealers, due to the refined tars unique chemical and molecular structure, are inherently resistant to these elements and provide protection superior to asphalt based pavement sealers. Regular application of coal tar emulsion pavement sealers will extend the life of the pavement and protect the investment it represents.
