• Abstract:
  Bridge deck simulators (BDSs), 6 in. (15 cm) concrete cubes with an embedded temperature probe, are intended as a cost-effective substitute for RWIS pavement sensors to represent conditions likely on bridge decks in an area near an RWIS station. In this study, the effectiveness of the BDSs to predict the temperature on nearby bridge decks was evaluated. Nine sites were selected by Ohio Department of Transportation (ODOT) across the state of Ohio (six in northeastern region and three in southwestern region) which were instrumented in BDSs and Nu Metrics pavement sensors on the bridge deck and (with one exception) on the road surface off the bridge. The use of BDSs appears to be unique to Ohio.
