A number of bonded overlays using portland cement grout have been employed in resurfacing pavements since 1954. This paper presents results of a survey on a number of these pavements to ascertain the performance of the overlays. The overlays were sounded and their surfaces inspected visually. Cores were taken to confirm areas of bond distress. Some of the specific projects surveyed are described. The introduction to the paper outlines some of the more important published material on the proper methods and techniques of bonding new concrete surfaces to old concrete surfaces.
