Description

Wooden guardrail posts are subject to splitting and rot as they age. Wooden guardrail posts that have been in service between eight and 15 years are evaluated and scheduled for replacement based on their condition and estimated remaining service life. Approximately 20,000 posts are replaced each year. Recycled plastic posts have a conservative service life of 30 years. The objective of this project was to determine if recycled guardrail posts should be accepted for use in the department's standard W-Beam (Weak Post) Unblocked Wood Post, Flexible, Longitudinal Roadside Barrier System.
