Abstract:
The purpose of the testing reported herein was to evaluate a new Wide Reusable Energy Absorbing Crash Terminal (REACT) system using High-Molecular-WeightiHigh-Density-Polyethylene (HMWIHDPE) cylinders. The Wide REACT is a redirective, non-gating 100 km/h crash cushion that can be used to shield rigid structures up to 2.75 m wide.
The following four National Cooperative Highway Research Program (NCHRP) Report 350 Test Level 3 crash tests are reported: 3-30, 3-31, 3-33, and 3-38. In NCHRP Report 350 test designation 3-30, an 820-kg passenger car impacts the crash cushion end on at a nominal speed and angle of 100 km/h and 0 degree. The test is primarily to evaluate occupant risk and vehicle trajectory. NCHRP Report 350 test 3-31 involves a 2000-kg pickup truck impacting the crash cushion end on at a nominal speed and angle of 100 km/h and 0 degree. The test is to evaluate structural adequacy and occupant risk. For NCHRP Report 350 test 3-33, a 2000-kg pickup truck impacts the crash cushion end on at a nominal speed and angle of 100 km/h and 15 degrees. The test is to evaluate occupant risk and vehicle trajectory. NCHRP Report 350 test 3-38 involves a 2000-kg pickup truck impacting the cushion at the critical impact point at a nominal speed and angle of 100 km/h and 20 degrees. The test is to evaluate the redirectional capability and vehicle trajectory.
All required NCHRP Report 350 criteria were met in each of the four tests.
