Thermal stresses at the extreme temperature conditions can cause various pavement distresses. These distresses may degrade the structural performance of bridge deck pavements (BDP), such as, upheaval, low-temperature cracking, reflective cracking, etc. It is essential to understand the influence of the extreme temperatures on the pavement distresses. Based on the analytical solutions of temperature in BDP, the simplified formulae for calculation of stresses for the extreme temperatures (maximum and minimum temperatures) in BDPs were developed in this study.The calculated results obtained from the developed simplified formulae were then compared with the data measured in the field. The differences between them were found to be within 2°C.
