Abstract:Oregon has twelve sites that are part of the Strategic Highway Research Program (SHRP), Long Term Pavement Performance (LTPP) studies. Part of the data gathering 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 project was completed, CRC produced a paper for SHRP titled, "Piezo-Electric Based Automatic Vehicle Classifier Pilot Project," December, 1989. This purpose of this report is to complement the CRC report and discuss the project from Oregon's perspective.
This project, an installation in asphalt concrete, is the first of two pilot projects planned by Oregon. The second pilot project, in Portland cement concrete, will be installed in the spring of 1990.
