GUARDRAIL SYSTEMS: SAFETY WITH TREATED W009

This bulletin summarizes significant occurrences that have spurred renewed interest in quardrail research. A state-of-the-art survey has been compiled (Ref. 1) and broad criteria for guardrail construction have subsequently been established. Safety is the paramount consideration. Guardrails must contain and re-direct errant vehicles, while minimizing (1) injury to passengers and (2) damage to both the vehicle and the guardrail system. Pressure treated wood is an ideal material for guardrail posts because it has (1) high resistance to impact loads, (2) long life, (3) pleasing, functional appearance, (4) relatively low cost, and (5) simplified installation through recently-developed techniques for driving. /Author/
