• Abstract:
  (ADTT) volumes, were selected to characterize axle weight and spacing spectra on Oregon state highways. ; Seasonal variations were considered by investigating data occurring over the four seasons: winter, spring, summer, ; and fall. WIM data were cleaned and filtered, and analyzed. Axle data, including group and individual axle weights ; as well as axle spacings, were evaluated. Hourly truck volumes were also examined. Results were summarized and ; statistics were developed for the characteristic data. The characterized Oregon WIM axle data were incorporated ; into the Mechanistic Empirical Pavement Design Guide (MEPDG) software program to permit State and ADTT ; volume-specific axle weight spectra, average axle group spacing, and hourly volume data to be used in the ; pavement analysis/design. In order to implement the Oregon WIM data, a “virtual” truck classification was created ; in the MEPDG program. The Oregon-specific data that were required for input into the MEPDG were hourly truck ; volume distribution, site-specific axle weight data, average number of axles per truck, and average axle spacing. ; Implementation of the Oregon WIM data will improve the pavement design process in the State by designing to ; more realistic local loading conditions.
