Superpave Pavement Design Temperatures in Estonia

This paper introduces the maximum and minimum pavement temperatures of Estonian asphalt pavements in accordance with calculation models developed for North America Norway. Historical meteorological data from 1992 to 2021 obtained 25 different weather stations Estonia were used as an input respective models. Comparison between demonstrated high variability design temperatures, thus significantly impacting bitumen grade selection. Based on road data, Norwegian Canadian provide most accurate temperature estimations conditions. Calculated upper lower-bound varied +52 °C +58 −22 −34 °C, respectively. All showed milder lower seasonal amplitudes coastal offshore areas. The results also indicated importance validating model suitability well correlation actual Baltic region.
