STUDY OF FROST AND ICE PREDICTION SYSTEM ON THE ROUGE RIVER BRIDGE

The objective of the study was to predict the formation of frost and ice on bridge decks using trends in the local meteorological conditions in time to apply countermeasures. In order to predict frost or ice formation, meteorological equipment was installed to measure air temperature, humidity, and deck temperature on a bridge. Based on results of the study, the roadway temperature is not normally more than 5 degrees below the air temperature indicating any prediction of frost would require at least 80% relative humidity. Two major detrimental effects precluded the use of the method as described. One was that the necessity of a sufficient amount of humidity in the air is the prime contributor to a frost condition, and this variable was the least predictable. The second was that salt used for removing snow and ice from the bridge deck remained on the roadway for approximately a week after application depressing the freezing point on the road surface and precluding any frost formation during the study period.
