• Abstract:
  The Midwest States Pooled Fund has been developing a new non-proprietary cable median barrier. This system ; incorporates four evenly spaced cables, Midwest Weak Posts spaced at 8 to 16 ft (2.4 to 4.9 m) intervals, and a bolted, ; tabbed bracket to attach the cables to each post. Full-scale crash testing was needed to evaluate the barrier’s safety ; performance. According to the Manual for Assessing Safety Hardware (MASH) updated/proposed testing matrix for cable ; barriers installed within a 6H:1V or median ditch, a series of eight full-scale tests are required to evaluate the safety ; performance of a system. A ninth test is required to establish the working width for systems with variable post spacing. ; Three full-scale crash tests were performed. Test no. MWP-4 was conducted according to MASH test no. 3-11 and ; utilized a 2270P pickup truck impacting the barrier on level terrain. The vehicle was contained by the barrier, and the test ; was deemed acceptable. Test no. MWP-6 was conducted according to MASH test no. 3-10 and utilized a 1100C passenger ; car impacting the barrier on level terrain. The vehicle was contained and redirected by the system. However, the system ; posts penetrated the occupant compartment through tearing and rupture of the vehicle floor board, and the test was deemed ; unacceptable. Test no. MWP-7 was also conducted with a 1100C vehicle according to MASH test no. 3-10. Alterations ; were made to the system posts. Although the vehicle was contained by the system, occupant compartment penetration by ; line posts was again observed. Test no. MWP-7 was deemed unacceptable.
