• Abstract:
  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. ; WisDOT’s Bureau of Highway Operations, (BOH) used this software, known as UWFROST, during the ’98-’99 and ’99-’00 winter seasons and ; found the software’s 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.
