One of the main issues in design of bridge pavement concerns rutting (permanent deformation). Traditional approach in rutting evaluation takes into account average seasonal temperatures. To get a better approximation, a different approach was developed. Advantages from the different approach were evaluated through a numerical analysis (based on temperatures logged through a specific in situ survey) aimed at predicting ruts depth in two cases, respectively taking into account the average seasonal temperatures (traditional approach) and the actual frequency distribution of the temperatures (different approach, based on the concept of temperature configuration). The comparison of both results with the ruts measured in site showed that, following the traditional approach, the rutting predicted are meaningfully underestimated, whereas the proposed approach allows an adequate and satisfactory prediction.
