Test 2: Midwest Roadside Safety Facility Crash Test TL5CMB-2
Test TL5CMB-2 was conducted by Midwest Roadside Safety Facility MwRSF (MwRSF) to evaluate the crash performance of a new concrete median barrier design according to the testing guidelines of NCHRP Report 350 for Test Level 5 impact conditions. The test involved a 79,705-lb (36,153-kg) tractor-semitrailer vehicle impacting a concrete median barrier at 52.7 mph (84.9 km/hr) and impact angle of 15.4 degrees. The test vehicle was a 1991 White GMC tractor with a 1988 Pines 48-ft (14.6-m) semitrailer. The test article was a 42 inch (1.067 m) tall concrete median barrier with an installation length of 200 ft (60.9 m).

The acceleration data from the test were collected using triaxial piezoresistive accelerometers, and the angular velocities were collected using Analog Systems 3-axis rate transducer. The Electronic Recording Devices (ERDs) were mounted at two locations: 1) the primary ERD set was mounted to the trailer floor on the inside of the trailer near the tandem axles of the trailer and 2) the secondary ERD set was mounted near the tractor tandem axles. Unfortunately, data were not recorded for the secondary ERD set due to a premature triggering of the ERD. Four AOS high-speed video cameras with recording speeds of 500 frames/sec and six digital video cameras with recording speeds of approximately 30 frames per second were used to film the crash test.
