Abstract
A method for repairing voids such as potholes in asphalt pavement by mixing a lossy microwave material in the tack used for the tack layer. The asphalt patch used to fill the pothole is relatively non-lossy so that a substantial portion of microwave energy applied to the upper surface penetrates through the asphalt patch and is absorbed in the tack layer. The heating of the tack layer is enhanced to improve the interface bond between the asphalt patch and the surface of the pothole.
