Scope

Scope: This specification is applicable to new and modified highway bridges that require the installation of HA-level guardrails. Other highway bridges can refer to this specification for use in their guardrail installations. Main technical content: This specification is based on the technical requirements for the design and construction of eight-level guardrails for highway bridges in China. It is compiled based on on-site surveys, theoretical calculations, finite element simulation analysis, full-scale vehicle collision tests, and engineering applications, combined with the experience gained from the design and construction of eight-level guardrails for bridges in recent years.
