• Abstract:
  A critical review of current standard details and specifications for NETC style bridge rails and transitions used by MaineDOT, NHDOT, RIDOT and VTrans was conducted to identify differences in material specifications and dimensional details. An initial performance assessment was made for each bridge rail design based on strength calculations and rail geometrics calculations for MASH loading conditions according to procedures in NCHRP 20-07 (Task 395). Preliminary recommendations were made for NETC bridge rail and AGT design details for further crash performance evaluations in this study.
