AASHTO - M 180

Standard Specification for Steel Components for Highway Guardrail

active, Most Current
Organization: AASHTO
Publication Date: 1 January 2023
Status: active
Page Count: 19
scope:

This specification covers steel components used in non-proprietary highway guardrail, including corrugated sheet steel prepared for use as guardrail beams, transition beams, end sections, buffer sections, terminal connectors, and backup plates; fasteners including standard and high-strength bolt, nuts, and washers; steel guardrail posts; and anchorage wire rope and swage fittings.

This specification covers coating, storage, and handling requirements for zinc-coated, zinc-alloy coated, uncoated, and atmospheric corrosion-resistant components used in highway guardrail.

Although some of the components covered under this specification are used in proprietary guardrail systems, these specifications do not purport to address all components of proprietary guardrail systems.

The values stated in U.S. customary units are to be regarded as the standard. The values given in parentheses are mathematical conversions to metric units that are provided for information only and are not considered the standard unless otherwise noted.
