Rowles Asphalt offers an alternative to emulsion sealers, in a premium Asphalt Rejuvenator Sealer, which only needs to be reapplied every 3-5 years. Installation is by high production, computer controlled equipment which results in a more accurate and even application. Since this product needs to be applied less frequently, its actual cost can be lower when broken down over the longer term. In addition to the cost savings, fewer applications also result in less disruption to your residents or customers. Asphalt Rejuvenator is best suited for use on new overlays or pavements that have not been seal coated. This product is a penetrant not a surface coating. It penetrates into the asphalt to chemically replasticize or rejuvenate the asphalt binder to improve pavement condition and reduce costly future cracking and repairs.
