Asphalt Seal Coating Rejuvenators

One of the first asphalt seal coating rejuvenators available which is still used today is Reclamite.  Reclamite is a lube oil base derivative that provides the asphalt the necessary maltenes to help keep the binder healthy.  The major drawback to Reclamite is that in most cases it is necessary to sand the product heavily to prevent tracking.

Another of the first products to come available was Gilsonite.  Gilsonite was a blend of Gilsonite ore and select asphalts blended together with a fast drying petroleum cutter stock.  Gilsonite has proven to provide the binder with the maltenes necessary to enhance their binding ability and as an added bonus Gilsonite contains a high carbon content that provides excellent UV protection from the sun. Gilsonite dries dry and requires no sanding.

Another product that was developed approximately 20 years ago is the DISSCO RS-90.  DISSCO RS-90 is a product made to meet today’s demands for a penetrating sealer and binder for existing asphalt pavement.  RS-90 was engineered to penetrate the pavement surface and rejuvenate the surface by replacing the oils and binders (maltines and polar compounds) that the sun and weather bake out of the pavement through time.  These maltines and polar compounds are necessary to keep your asphalt pavement in good repair by binding the surface together.  RS-90 keeps the pavement flexible thus preventing the surface from deteriorating and becoming brittle.  Keeping eh pavement flexible helps prevent the pavement from cracking thereby keeping water from entering and softening the base course which can result in pavement breakup and costly repairs.

RS-90 can be used on old asphalt, new asphalt, shoulders, curbs, chuckhole patches, and also as tack coat.  It may also be used to black out pavement markings, any asphalt markings, and in any asphalt maintenance program requiring superior sealing and binding characteristics at low cost.

RS-90 is a liquefied bitumen consisting of selct grade asphalt binders and plasticizers blended with a fast drying petroleum cutter stock.  RS-90 contains antioxidants, adhesives, and chemicals not present in highly refined crude oil base asphalts.  Properly applied, RS-90 seals out water to protect the base; eliminates water stripping; seals in resins and oils necessary for pavement flexibility; adds antioxidants; binders; and a tough, durable surface to modern, highly refined asphalts.  RS-90 formulations are designed to replace and preserve the chemicals beneficial to pavement life.  AS an integral part of the pavement mat, RS-90 adds many years of serviceable life to asphaltic concretes.

DISSCO RS-90 along with other rejuvenators are generally very cost effective and easy to apply.  Application of RS-90 asphalt seal coat can be achieved using almost any positive pressure spray applicator utilizing a hand wand or using any standard asphalt distributor truck with computer controlled rate controls.
