In 1994, a ramp containing two AC and two PCC sections in the SPS-8 experiment was constructed on the Ohio SHRP Test Road. In 1996, 36 more sections in the SPS-1, SPS-2 and SPS-9 experiments were opened to traffic on the mainline pavement. The response and performance of these sections, climatic information from an on-site weather station, and subsurface environmental conditions from sensors installed in several test sections, and traffic loading from an on-site weigh-in-motion (WIM) system have been monitored and incorporated into the national LTPP database. Analyses of these data have been published in a number of reports, technical papers and bulletins. The research project documented in this report was the latest effort by ODOT to continue monitoring the response and performance of many of the original 40 test sections and several sections constructed later to replace the lighter designs which, as anticipated, showed early distress. Data in this report cover the years 2000-2005. In addition to the new response and performance data obtained on the test road, this report includes: an analysis of current methodologies to mathematically model AC and PCC pavement structures, a petrography analysis of concrete from three different PCC pavement mixes and a lean concrete base, and an in-depth analysis of WIM data. / NOTE: Technical rept. / Supplementary Notes: Sponsored by Ohio Dept. of Transportation, Columbus.
