What crash testing has been performed with BRIFEN?

BRIFEN Wire Rope Safety Barrier has been fully crash tested and evaluated according to the specifications for Test Level 3 (TL3) of the AASHTO Manual for Assessing Safety Hardware (MASH).

The MASH specification is an update to and supersedes NCHRP Report 350 for the purposes of evaluating new safety hardware devices.

MASH is also the basis of testing procedures for road safety systems as stated in AS/NZS 3845.1: 2015 Road Safety Barrier System and Devices.

What are the differences between MASH and NCHRP Report 350 for the evaluation of wire rope barriers?

The changes in crash test evaluation can be summarised as follows;

  • The small car test is now performed with 1100kg vehicle travelling at 100km/h and 25 degrees. This is an increase in impact energy of 205% when compared with NCHRP-350.
  • The pick-up test is now performed with 2270kg vehicle travelling at 100km/h and 25 degrees. This is an increase in impact energy of 13% when compared with NCHRP-350.
  • The minimum test article length is now 183m between anchors.
  • The cable tension must be set to the value recommended for 38° Celsius.

Why are the deflections larger for MASH tested wire rope barriers?

Under NCHRP-350, it was common for proprietors to crash test short installation lengths and set the cable tensions to their highest value producing low deflection results.

The MASH evaluation is considered more representative of real-life installations and considers the effects of barrier length and cable tensions.

The increase in vehicle impact energy combined with the changes in barrier setup produces larger deflection results when compared with NCHRP-350.
