Section 5: End Treatment of GuardrailAnchor: #i1005475
Guardrail systems must be anchored at both ends to acceptable end treatments, buried terminals, wingwalls, concrete traffic barriers, etc., so that full tensile strength of the rail may be developed.
Approved end treatments have been developed and are recommended for the upstream end of a guardrail system. These approved end treatments shall be used unless the guardrail terminal is located on the downstream end [with respect to adjacent traffic—see Figure A-4 of the guardrail and outside the horizontal clearance for opposing traffic. In that case a twisted, buried end terminal anchor section without offset remains acceptable for use.
