NYSDOT Transition between HPBO and Box Beam

Report Number(s): TRP-03-442-25

Description: The test installation consisted of an approximately 187 ft long New York State’s HPBO to box beam transition, as shown in Figures 1 through 38. Photographs of the NYHBT and NYBHT test installations are shown in Figures 39 through 43 and Figures 44 through 46, respectively. The installation for the box beam to HPBO transition (NYBHT) was identical to the installation for HPBO to box beam transition (NYHBT). The only differences between the two systems were the impact points, direction of travel, and the posts were numbered beginning at the upstream end at the box beam instead of the upstream end of the HPBO. The New York Standard sheet for the box beam to HPBO transition is shown in Appendix B. Detailed drawings of the box beam to HPBO transition are shown in Appendix C. Material specifications, mill certifications, and certificates of conformity for the system materials are shown in Appendix D.
