About this file
This document is a technical specification section (Section 10 14 53) for Traffic Signage, specifically detailing requirements for traffic signs at Joint Base Lewis-McChord (JBLM). The specification provides comprehensive guidelines for sign materials, fabrication, and installation, including mandatory compliance with the Manual on Uniform Traffic Control Devices (MUTCD) and SDDCTEA Pam 55-17. Key requirements include using galvanized steel tubing for sign posts, applying retroreflective sheeting that meets ASTM D4956 standards, and using specific materials like aluminum sheeting and reflective materials.
The document outlines detailed technical specifications for sign construction, including requirements for steel posts (various types like flanged channel, perforated steel tube, and structural steel H section), aluminum sign panels, retroreflective sheeting, and hardware. Specific installation instructions are provided, such as how to mount signs, treat signs in different areas (cantonment vs. range/training), and ensure proper positioning and visibility. The specification also includes provisions for delineator posts and retroreflectors, emphasizing safety and visibility standards for traffic signage at the military installation.
