Although typically used for rigid pavement surface restoration, diamond grinding can be used to eliminate relatively small surface distortions in existing rigid pavement prior to flexible or rigid overlays. Because it roughens the existing rigid pavement surface, diamond grinding also improves the bond between the existing pavement and the overlay.
