LAWRENCE CO. – Asphalt rejuvenation is the process of restoring chemical properties that have been deteriorating since the moment new asphalt was laid down. Unlike conventional asphalt emulsion sealers that are water-based, asphalt rejuvenators are made from coal tar blended with aromatic oils and solvents.
According to Highway Superintendent Brandi Webb the new procedure will begin soon.
“This is a new procedure for us,” said Commissioner President Rodney Fish. “It will be good to see how this progresses in the county.”
An asphalt rejuvenator penetrates the asphalt well below the surface to chemically revitalize and protect the asphalt binder by replacing the tars and oils lost due to oxidation. This process also seals the pavement against air, water, and chemical contaminants thereby slowing oxidation and deterioration which extends the effective service life of the pavement.
Highway crews continue to cut brush, mow, and patch county roads.
