SURVEY RESULTS OF THE INCIDENCE OF PREMATURE BRIDGE DECK ICING

The occurrence of frost on bridge decks is a serious problem in Minnesota. So that we could become better acquainted with differential frosting, our maintenance personnel were asked to collect data. A total of 35,198 observations were made during two winters. Originally, we thought that we would be able to predict when a bridge deck would frost; this was not the case. Frosting occurred over a large temperature range and did not depend on any logical combination of variables. Since predictions of deck frosting cannot be made reliably by visual observations, we intend to install a frost detection sensor and to correlate the sensor alarm with the visual observations. /Author/
