Investigation of Material Requirements for Highway Guardrail Systems
Manufacturers and hardware suppliers use significant time and resources to provide guardrail
materials according to one state agency’s design and material standards, only to start the process
all over again to satisfy another state’s specifications. Such inconsistency often leads to increased
fabrication costs for hardware suppliers that are ultimately passed along to transportation agencies.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 1020: Investigation of Material Requirements for Highway Guardrail Systems
provides a comprehensive review of the various current standards and proposes needed revisions
to bring specifications into conformance with current requirements and the state of practice for
highway guardrail systems.
