Application of High-Performance Concrete Overlays (Whitetopping) for Safety at Signalized Intersections

In 2002, the Rhode Island Department of Transportation began a whitetopping demonstration project. The location, in a suburban area, included a downhill, signalized intersection that had severe rutting and shoving of the asphalt pavement. The department's Research and Technology Development section worked with a team from the Design, Construction, Materials, and Maintenance sections to accomplish location selection, planning, design, drafting of contract documents, and construction management of the project. This summary highlights the issues involved with the project and elucidates its problems, issues, and successes. It covers planning, selecting a project site, defining design procedures, developing a materials quality control/quality assurance (QC/QA) plan, and partnering with the concrete construction industry to devise plans, specifications, and contract special provisions--quantities and scheduling. Covered are preliminary operation requirements, such as mix design and placement of a test slab, operation, relevant (QC/QA) data, and monitoring over the last year.
