325.13R-06: Concrete Overlays for Pavement Rehabilitation
| Published By | Publication Date | Number of Pages |
| ACI | 2006 | 39 |
This report provides information on the use of concrete overlays for rehabilitation of both concrete (rigid) and asphalt (flexible) pavements. Selection, design, and construction of both bonded and unbonded overlays are discussed. The overlay categories reviewed include bonded concrete overlays, unbonded concrete overlays, white topping overlays, and concrete overlays bonded to asphalt (ultra-thin and thin white topping). Information is also provided on selecting overlay alternatives. Significant portions of this document are based on a synthesis report prepared for the Federal Highway Administration (FHWA) by Applied Pavement Technology, Inc., under contract number DTFH61-00-P-00507. The report, “Portland Cement Concrete Overlays: State of the Technology Synthesis,” is available from the FHWA as publication FHWA-IF-02-045. Keywords: bond; concrete; joint; overlay; pavement (concrete); rehabilitation; repair.
