• 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.
