• Abstract:
  Asphalt and concrete pavement surface temperatures were compared at a location on U.S. Route 40 in
  
  northern Utah where asphalt and concrete meet end to end at the base of the mountain pass. An environmental
  
  sensor station was installed to facilitate monitoring of asphalt and concrete pavement surface temperatures, as well
  
  as selected climatic variables, at the site. To compare the surface temperatures of the concrete and asphalt
  
  pavements during freezing conditions, multivariate regression analyses were performed on data collected during the
  
  three winter seasons from 2009 to 2012. Equations were generated for three response variables, including the
  
  asphalt surface temperature, concrete surface temperature, and difference in temperatures between the asphalt and
  
  concrete surfaces.
  
  The statistical models developed in the analyses show that the surface temperature of both asphalt and
  
  concrete pavement increases with increasing air temperature and decreases with increasing relative humidity and
  
  wind speed and that the difference in pavement temperatures decreases with decreasing air temperature. For the
  
  studied site, the data indicate that concrete pavement will experience freezing before asphalt pavement for all time
  
  periods except late afternoon, when the pavement types are predicted to freeze at the same air temperature.
  
  Therefore, for material properties and environmental conditions similar to those evaluated in this study, asphalt
  
  would require less winter maintenance, on average, than concrete. Due to the interactions among albedo, specific
  
  heat, and thermal conductivity, the actual thermal behavior of a given pavement will depend on the material
  
  properties and environmental conditions specific to the site.
