TWEE BOTSPROEVEN OP DE SLIPFORM STEP-BARRIER. VERSLAG VAN TWEE BOTSPROEVEN, EEN PERSONENAUTO BIJ 100 KM/UUR EN EEN BUS BIJ 70 KM/UUR, UITGEVOERD DOOR TESTINSTITUUT LIER IN FRANKRIJK

An aim of collision trials on actual scale is to assess whether the developed slipform STEP barrier meets the 'higher containment level' H2. The trials required for assessment are TB 11 and TB 51. TB 11 is a test using a light passenger car with a mass of 900 kg, travelling at a speed of 100 km/h and colliding at an angle of 20 degrees. TB 51 is a test using a bus with a mass of 13,000 kg, travelling at a speed of 70 km/h and colliding at an angle of 20 degrees. This report gives an account of these both collision tests conducted on the Dutch Department of Public Works slipform STEP barrier. The collision with the passenger car is very stable. There is no rolling movement. The angle of exit remains within the accepted values, and is 7 degrees. The Acceleration Severity Index (ASI) value of the passenger car barely meets level B (ASI lower than or equal to 1.4). The collision with the bus also proceeds well, with a small angle of exit of maximally 1 degree. The barrier is not ruptured. The maximal rolling angle is greatest during the 'rear end' effect: about 20 degrees. It is concluded that the slipform STEP barrier meets the 'higher containment level' H2.
