本报告提供了混凝土（刚性）和沥青（柔性）路面修复中使用混凝土覆盖层的信息。讨论了粘结面层和非粘结面层的选择、设计和施工。审查的覆盖层类别包括粘结混凝土覆盖层、无粘结混凝土覆盖层、白色面层覆盖层和粘结到沥青的混凝土覆盖层（超薄和薄白色面层）。还提供了有关选择覆盖替代方案的信息。本文件的重要部分基于应用路面技术有限公司为联邦公路管理局（FHWA）编制的综合报告，合同号为DTFH61-00-P-00507。该报告“波特兰水泥混凝土覆盖层:技术综合状态”可从FHWA出版物FHWA获得- IF-02-045。

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.
