Crash Test of PennDOT's Portable F-Shaped Concrete Barrier. University-BasedResearch, Education and Technology Transfer Program

摘要

The objective of the test program described in this report was to evaluate theperformance of PennDOT's portable F-shaped concrete barrier when subjected to NCHP level-3 testing criteria based on test designation 3-11. The scope of the test program consisted of a single test in which a 1993 Fort F-250 pick-up truck impacted the barrier at 100 km/h (62 mph) at an impact angle of 25 degrees. Following impact with the barrier, the vehicle mounted the barrier and rotated counter-clockwise with the rear of the vehicle crossing over the barrier. The front wheels came in contact with the ground and the vehicle began a passenger-side leading roll, coming to rest in a grassy area after rolling three times. Significant movement of the barrier occurred during impact, resuling in an undesirable trajectory of the vehicles. Spalling occurred at barrier joints 7 and 8, resulting in the separation of adjacent barrier sections in the vicinity of the impact.
