The development and testing of a steel fence and the construction and testing of a concrete barrier are described; both fence and barrier were impacted with vehicles ranging from a small car to a 38 tonne articulated heavy goods vehicle. The cars at 112 km/hr and the 16 tonne heavy goods vehicles at 80 km/hr were contained and redirected by the fence and the barrier after impacting at an angle of 15 degrees; in addition, a 38 tonne articulated heavy goods vehicle and a 51 seat coach were redirected by the steel fence. Further work is needed to improve the fence response to 25 degree impacts. Modification to the concrete barrier may be necessary before impact testing at 25 degrees. (A) This is paper 1 of the TRRL papers presented to the 1986 TRB annual meeting.
