Assessment of The SPS-7 Bonded Concrete Overlays Experiment: Final Report

PDF Version (2.41 MB)

PDF files can be viewed with the Acrobat® Reader®


The Long Term Pavement Performance (LTPP) program Specific Pavement Studies 7 (SPS-7) experiment was undertaken to explore the use of bonded concrete overlays as a means for rehabilitating concrete pavements. However, only four of the planned 12 SPS-7 projects were built. This report documents an assessment of the SPS-7 experiment as it exists today. It was prepared to provide a factual basis for discussions, with the participating State highway agencies and other agencies involved in research concerned with bonded concrete overlays, as to how we might best use them to maximize our learning on this important topic.

Due to the nature of this report, broad dissemination is not planned. Copies will be provided to the States participating in the SPS-7 and other bonded concrete overlay experiments. Others may obtain the report through the National Technical Information Service.
