Abstract
AbstractThe events of recent years indicate climate change in nature. Climate change could affect the lifetime of transport infrastructure. Changes in the temperature, humidity, and use of de‐icing material may stimulate the development of damages in road and bridge structures. According to Latvian Environment, Geology, and Meteorology Centre data, average air temperature values have increased by 0.7 °C (1981‐2010 compared to 1961‐1990 g). Road maintenance organizations need information on the actual weather conditions on each road: above the road pavement, on the surface, and below the surface. Sixtyfive meteorological stations on roads throughout Latvia's territory provide this information. This paper analyzes data from six road metrological stations obtained from 2001 to 2021. The results show that over the 20 years period, the average temperature determined nearby asphalt pavement of the road has increased by 1.4 C. This is because the road asphalt pavement heats more, and the temperature measured in its vicinity is higher and should be considered when modeling the development of damage to the transport infrastructure.
