SUMMARY OF CONCRETE OVERLAYS

Rachel Lopez

Open publisher page 1 citations

Abstract

Concrete pavement overlays are new concrete surfaces built over existing concrete pavements as well as bituminous pavements with flexible bases or old concrete pavements which have already had one or more bituminous overlays. Overlays of old concrete pavement may be bonded, partially bonded, or unbonded. The type of overlay and the thickness will vary and depend to a large extent on the type and condition of the existing pavement to be resurfaced. The paper discusses the various types of concrete overlays, including applications and limitations, and reports on a number of projects that have been in service for several years.
