• Abstract:
  From April 1982 through October 1983 surface temperatures were measured on seven asphalt concrete pavement test sections in Fairbanks. The seven test sections included an untreated asphalt concrete pavement, white-painted pavement, yellow-painted pavement, white marble C-chips, B-chips, dark grey C-chips and dark grey E-chips. Air temperatures were also measured throughout the experiment. Incident and reflected shortwave radiation, incoming and emitted longwave radiation, wind speed, wind direction and surface albedo observations with a hand-held radiometer were measured during the 1982 summer. Each of the test sections was approximately 16 ft wide by 50 ft long. The n-factors varied from 1.53 on the untreated pavement to 1.22 on the white-painted pavement during the 1982 suummer. The n-factors on the white- and yellow-painted pavements increased substantially during the 1983 summer because the test areas were not repainted. Values for all of the test sections except the white- and yellow-painted ones were lower than expected due to traffic-induced turbulence. (Author)
