Abstract
A precast concrete road repair panel is configured to be received in a prepared portion of an existing road under repair. The underside of the panel is textured to receive a grout or other settable composition suitable to affix the repair panel to the existing road sub-base or underlayment. The panel is provided with leveling plates that can be adjusted to ensure that the top surface of the repair panel is flush with the existing road surface. Openings are provided throughout the panel for introducing grout or other similar composition to fix the precast panel in place. Dowels, rods or rebar may be incorporated into the junction between adjacent precast panels or between the precast panel and the existing road surface.
