• Abstract:
  This volume reports on experiments at three pavement sites in New York, I490 in Rochester, RT9A in New York City, ; and I86 near Angelica. I490 included JPCP sections instrumented to monitor loss of support from curling and warping ; during curing and early use, plus an experiment on different dowel bar and tie bar configurations. Instrumentation ; included linear variable displacement transducers (LVDTs) measuring displacement and vibrating wire strain gauges ; (VWSGs) measuring strain, stress, and temperature. Data were gathered by applying falling weight deflectometer ; (FWD) and with a Dipstick® and a profilometer. Environmental and response data from the embedded instrumentation ; were collected from construction in June 2002 through 2004, and FWD responses were measured during 2006-2011. ; In conclusion, evidence for loss of support resulting from both warping and built-in curling was found. Among the ; three dowel bar configurations, E2, which had the narrowest spacing and the smallest bar cross-sections, had test ; sections with the least curling and the best FWD load transfer efficiency (LTE) under negative temperature gradient ; (morning). All sections performed well under positive temperature gradient (afternoon), with LTE>93%. ; Instrumentation of a PCC section on RT9A adjacent to the Freedom Tower site in Manhattan, New York City, was ; installed in June 2008 to monitor the heavy construction related traffic. Instrumentation included LVDTs, VWSG, ; other strain gauges, and thermocouples. FWD data were collected after two months, but further data could not be ; collected due to restrictions accessing the site. ; On I86 near Angelica, a JRCP pavement was rubblized and covered with a 20 cm (8 in) asphalt pavement. A ; special test section substituted a perpetual pavement structure for the standard design, and included four layers ranging ; from 100 mm (4 in) to 40 mm (1.57 in) in thickness. The test pavement was instrumented with LVDTs, ; thermocouples, strain gauges, and pressure cells. FWD testing was conducted November 2006 through August 2011. ; After nearly five years of service, very slight distress could be observed in the standard AC pavement, and no distress ; was observed in the perpetual pavement section.
