Samenvatting
Development of the slotted-Rail Breakaway Cable Terminal (SRBCT), a low-cost end treatment for W-beam guardrails, is presented in this paper. Longitudinal slots in guardrail segments are used to weaken the W-beam for head-on impacts, thereby allowing a nearly standard BCT design to meet nationally recognised safety standards. Static and dynamic laboratory testing of buckling characteristics of modified W-beam sections are presented. Full-scale crash tests of the SRBCT are described.
