INTENDED USE Thrie-Beam Bullnose End Terminal (SET03a-b) is a non-proprietary system for shielding of median hazards and gore areas. Lateral clearance between the tangent segments of the bullnose barrier system and the face of the hazard must be considered. Previous testing conducted by TTI on a thrie beam longitudinal barrier system found a maximum dynamic deflection of 26 ¾” [674] and a working width of approximately 46 1/8” [1172]. Based on this data, the minimum recommended lateral clearance between the back of the posts and the face of the hazard is 27.6” [700]. In addition, a minimum of 62’-9” [19.125-m] of guardrail, as measured longitudinally, or five sections of guardrail downstream of post no. 1 of the system is recommended in front of any hazard in order to prevent vehicle impacts with the hazard during end-on impacts with the system. The Thrie-Beam Bullnose End Terminal is TL-3 NCHRP 350 accepted.
