Frozen Road Operation Improvements
A research study in 1996-1997, sponsored by WisDOT, was undertaken by the PI of this proposal to develop a computer model to correlate climate and pavement data for the year in progress in order to project when to impose and lift weight restrictions. Our research team collected field data relating to weather and road stiffness over two winter-spring periods, which enabled the development of a six-phase computer model integrating weather conditions, heat transfer, roadway stiffness, stress-strain effects, and estimates of pavement damage load (EDL) for a given road 30, 60, 90, or 120 days into the future based on user-supplied average daily temperatures experienced in the year to date. WisDOTs Bureau of Highway Operations, (BOH) used this software, known as UWFROST, during the 98-99 and 99-00 winter seasons and found the softwares fall freezing and spring thawing projections to be quite accurate for normal winters. Since this study was conducted, additional data has been collected using frost tubes to declare the roads frozen and then unfrozen. Changes in Wisconsin climate have also been noted which will affect the model. More data has been collected at the national level, which relates pavement material moduli to temperature. All of which needs to be integrated into an updated version of the model.
