| 摘要： | A jointed concrete pavement on I-490 near Rochester, NY, was reconstructed using three different dowel bar spacings in eastbound test sections. Two sections in the westbound direction were instrumented to monitor environmental strain, deflections, and pavement temperatures. Monitoring of the westbound sections was conducted at the time of construction, after 28 days of curing, and at various intervals over the next two years. The instrumentation included deep and shallow linear variable differential transducers (LVDTs) to measure displacements in the center and the corners of the slabs, thermocouples at four depths near the center and at the corner of the slab, and vibrating wire strain gages with built-in thermistors in the center and the left wheel path. Air temperature data were also gathered during monitoring periods. Data were taken from the instruments at the time of construction, and at 37 days (after curing), 12 months, 16 months, and 28 months after construction. In addition to instrumentation readings taken over an approximately 24-hour period, each visit included slab shape measurements made with a Dipstick(trademark), and deflections measured with a falling weight deflectometer (FWD) on the westbound sections. The final data collection visit, in October 2004, also included FWD testing and profilometer measurements on the eastbound sections. / Supplementary Notes: See also PB2006-105741, PB2006-110546 and PB2007-106467.
