A MIX MATCH : GROUP OF REPAIR TECHNIQUES MAY BE THE RIGHT WAY TO GO

This article describes education efforts by the American Concrete Pavement Association to dispel misconceptions about the difficulty of rehabilitating concrete pavements. Among the mistakes the campaign hopes DOTs will avoid are placing flexible overlays on concrete pavements that need only restoring or resurfacing, or premature destruction of concrete pavements and their replacement when other alternatives would have served just as well and cost less. Among the alternatives discussed are concrete pavement maintenance, restoration and reconstruction, which include engineered procedures to manage the rate of concrete pavement deterioration. Preventive and corrective techniques include joint and crack resealing, retrofitting concrete shoulders, edge drain work, dowel bar retrofits, slab stabilization, full-depth patching, partiale9epth patching and diamond grinding. Concrete overlays are also discussed.
