Thermal analysis of pavement for the east Bielsko-Biala bypass

Road surface temperature and road longitudinal temperature gradient value, may present a considerable challenge in the matter of traffic safety. The awareness of thermal conditions with due regard to location of significant temperature variability areas could be desirable information for road infrastructure operators. That knowledge would allow to select an appropriate location of traffic signs, variable message signs and road weather stations. In the wintertime it would enable road maintenance authorities to take more efficient actions. In the study authors present road surface temperature variability analysis based on measurements conducted on a 6.25-kilometer section of eastern bypass of Bielsko-Biala city. In analysis authors used the data from mobile road weather sensor. The sensor enables to measure road surface and dew point temperature, water film height and calculated friction.
