Frost index value in Serbia from 2014 to 2020

Over time, the pavement structure deteriorates. Factors that contribute to the deterioration of the pavement structure are traffic load, material properties and climate influences. Low temperatures lead to freezing of water and the appearance of ice lenses, which raises pavement structure. It is necessary to check the resistance of the pavement structure to the harmful effects of frost. This paper presents the calculation of the frost index value for six meteorological stations in Serbia for the period from 2014 to 2020. Relevant frost index value for the 20-year and 10-year project period are also given.
