PIEZO-ELECTRIC AUTOMATIC VEHICLE CLASSIFICATION SYSTEM. FINAL REPORT

Oregon has twelve pavement test sites that are part of the Strategic Highway Research Program (SHRP), Long Term Pavement Performance (LTPP) studies. Part of the data gatherng on these sites involves vehicle weight and classification. This pilot project was to help SHRP show others how to specify, procure and install equipment that would provide the necessary data to characterize the sites for the LTPP program. Castle Rock Consultants (CRC) provided specifications and technical aid for the first phase of this project. After the first phase was completed, CRC produced a paper for SHRP titled, "Piezo-Electric Based Automatic Vehicle Classifier Pilot Project," December, 1989. This report complements the CRC report and discusses the total project from Oregon's perspective. This report covers procurement of equipment and installation on two pilot sites, one for asphalt concrete and the second for portland cement concrete. Oregon used the results from this study to write the specifications for contractor installation of the ten remaining sites.
