MASH & NCHRP-350 TL3 Crash Tests

FREE-STANDING

Highways: Free-standing NCHRP-350, Test Level 3, Crash Tested

Meets & exceeds requirements for Jersey, F-Shape, Constant Slope, and Other Barrier Profiles.

Certified Crash Test Results: NCHRP-350 Report Test Designation 3-11

"SUMMARY OF FINDING: The J-J Hooks Jersey shape PCB system contained and redirected the vehicle. The vehicle did not penetrate, underride, nor override the installation. Maximum deflection of the barriers was 1.30 m. Fragments from the PCB were small and did not penetrate nor show potential for penetrating the occupant compartment, nor would they present undue hazard to others in the area. Maximum reduction of space was 7.9% in the instrument panel to the floor pan area, which was judged to not cause serious injuries. The vehicle remained upright during and after the collision event. The vehicle did not intrude into adjacent traffic lanes as it exited the test site ... Exit angle as loss of contact with the PCB was 9.4 degrees which is 38% of the impact angle."

Since May 26, 2017 (FHWA Open Letter), the FHWA will not issue Federal-aid Eligibility Letters unless the full suite of recommended tests described in AASHTO MASH-16 are completed. For that reason, both 3-10 and 3-11 tests are shown below. To determine the maximum dynamic deflection, refer to the 3-11 tests.

Certified Crash Test Results: FREE-STANDING MASH Report Test Designation 3-10

"SUMMARY OF RESULTS: The J-J Hooks Free-Standing PCB contained and redirected the 1100C vehicle. The vehicle did not penetrate, underride, or override the installation. Maximum dynamic deflection during the test was 26.2 inches. No detached elements, fragments, or other debris was present to penetrate or show potential for penetrating the occupant compartment, or to present undue hazard to others in the area. No occupant compartment deformation or intrusion occurred. The 1100C vehicle remained upright during and after the collision event. Maximum roll and pitch angles were 25° and 10°, respectively. Maximum longitudinal OIV was 14.4ft/s, and maximum lateral OIV was 22.0ft/s. Maximum longitudinal occupant ridedown acceleration was 4.2g, and maximum lateral occupant ridedown acceleration was 9.6g. CONCLUSION: The J-J Hooks Free-Standing PCB preformed acceptably for MASH TL3 test for longitudinal barriers.”

"SUMMARY OF RESULTS: The Easi-Set MASH Free-Standing Barrier contained and redirected the 2270P vehicle. The vehicle did not penetrate, underride, or override the installation. Maximum dynamic deflection during the test was 64.2 inches. Only small pieces of the concrete spalled off the installation; however, these pieces did not penetrate or show potential to penetrate the occupant compartment, nor present hazard to others in the area. No occupant compartment deformation or intrusion occurred. The 2270P vehicle remained stable during and after the collision event. Maximum roll and pitch angles were 24 degrees and 13 degrees, respectively. Occupant risk factors were within the preferred values specified in MASH.” “Longitudinal Barrier Test 3-11 was performed in accordance with MASH (2009) which is consistent with MASH (2016) 2nd Edition”

Highways: Free-standing MASH, Test Level 3, Crash Tested (12" J-Hook, 20' section)

Certified Crash Test Results: FREE-STANDING MASH Report Test Designation 3-10

"SUMMARY OF FINDINGS AND CONCLUSION: The Easi-Set J-J Hooks barrier system successfully contained and redirected an 1100C test vehicle impacting the test article at 25.1 degrees and a velocity of 98 km/h (60 mph). Maximum dynamic deflection of the barriers was 32.3 inches. No debris or detached elements penetrated or showed potential to penetrate the occupant compartment. No fragments were distributed outside of the vehicle trajectory. The trajectory of the vehicle was such that it would not have presented an undue hazard to other traffic, pedestrians or work zone personnel. The vehicle remained upright during and after the impact and vehicle stability was considered satisfactory. Occupant risk factors satisfied the test criteria and the vehicle exit trajectory remained within preferred limits. The J-J Hooks barrier system was judged to have satisfied all of the evaluation criteria for the MASH Test 3-10."

"SUMMARY OF FINDINGS AND CONCLUSION: The Easi-Set J-J Hooks barrier system successfully contained and redirected an 2270P test vehicle impacting the test article at 24.7 degrees and a velocity of 99 km/h (61.5 mph). Maximum dynamic deflection of the barriers was 63 inches. No debris or detached elements penetrated or showed potential to penetrate the occupant compartment. No fragments were distributed outside of the vehicle trajectory. The trajectory of the vehicle was such that it would not have presented an undue hazard to other traffic, pedestrians or work zone personnel. The vehicle remained upright during and after the impact and vehicle stability was considered satisfactory. Occupant risk factors satisfied the test criteria and the vehicle exit trajectory remained within preferred limits.
