Since the early 1970 s, AASHTO ARTBA AGC Task Force 13 has worked to standardize roadside hardware through developing guides. Printed guides in 1973 1979 1995. Slide 3
Today: Online Guide Slide 4
Today there are really NINE guides Components Original Barrier Hardware Bridge Rail Systems Transition Systems Sign Support Systems Luminaire Support Systems Work Zone Systems Under development Crash Cushion Systems Under development End Treatment / Terminal Systems Under development Standardization of nomenclature System to system compatibility and interactivity Listing of components used in systems systems used by components Online accessibility no need to install anything Browser-based interface removes compatibility issues between computer types (Windows, Macintosh, Linux, ios, Android, etc.) Constant and continual updates THE definitive guide, recognized by RDG; Free to all!

4 th Edition Roadside Design Guide Slide 6 Section 5.1.2: The AASHTO-Associated General Contractors of America (AGC)-American Road and Transportation Builders Association (ARTBA) Joint Committee Task Force 13 report, A Guide to Standardized Highway Barrier Hardware is a depository of engineering drawings for a multitude of guardrail components and systems. Each system is given a unique designation used to catalog the different systems and variations of each system. A web site has been established for each supported system, and is available at http://www.aashtotf13.org
What is a Designator? An identifier that unambiguously refers to a particular part or system. Slide 7
Each Designator Contains: Category System or Component Function Kind of System or Component Type Material / Compatibility / More Specific Information Sequence # - Assigned Numerically Option Assigned Alphabetically Slide 8
