This paper presents the details on using the Mechanistic-Empirical Pavement Design Guide (MEPDG) for the local conditions in Poland. In particular, data from the high-quality Weigh-in-Motion (WIM) station in Poland was processed in order to prepare site-specific traffic inputs at the Level 1. After stringent Quality Control (QC), WIM data were used to determine site-specific traffic inputs including the percent of truck traffic in design direction, truck monthly adjustment factors (MAF), FHWA vehicle class distribution (VCD), truck hourly distribution factors (THDF), axle load factors (ALS) and average number of axle groups per vehicle (AGPV). Traffic factors were then input to the MEPDG software and four different trial pavement structures typical for Poland conditions were analyzed. Pavements were designed with the local materials and their properties were simulated at Level 3. In order to address climatic conditions typical for Poland, pavements were placed in two different climate conditions represented by two weather stations located in Evanston, WY and St. Louis, IL. This study demonstrated that there is a noticeable effect of the site-specific traffic inputs on the pavement performance, especially in terms of the AC rutting and total rutting. If the MEPDG or similar concept is implemented in Poland, the traffic inputs should be determined from the local WIM stations rather than the default traffic values incorporated in the MEPDG.
