Guardrails are one of the widely used passive safety devices designed to absorb loads applied by impacting vehicles. In this paper, development process of a new lightweight L1 containment level steel guardrail, called AG04-2.0, is explained. A series of full-scale crash tests were performed for the crashworthiness evaluation of AG04-2.0 system. AG04-2.0 failed to meet the EN1317 criteria at 10,000 kg truck test, called TB42. In the subsequent TB42 test when another brand truck was used the identical system successfully met the criteria. Additional crash tests, TB11 and TB32, were performed on AG04-2.0 system with 900 and 1500 kg passenger cars, respectively. To determine the effect of rail type on crash test performance both A and B type rails were utilized in the tests. Based on the extensive evaluations AG04-2.0 successfully passed all six crash tests and met L1 containment level requirements for both A and B type rails. Test results show that the difference in performance for the guardrail incorporating either A or B rail is fairly small. Moreover, it was concluded that variation in properties of 10,000 kg truck plays an important role in crash test outcome and thus a more detailed vehicle selection criteria in EN1317 are recommended.
