Task Force 13

Task Force 13 develops, recommends, and promotes standards and specifications for bridge and road hardware used by highway and transportation agencies on the nation's roadways.  Task Force 13 is a committee of concerned and experienced representatives from industry, academia, and state and federal transportation departments.  Task Force 13 serves the Joint AASHTO-AGC-ARTBA Subcommittee on New Highway Materials and Technologies, whose mission is to develop guide specifications for new materials and technologies identified for use in highway construction projects.  The present Joint Committee was established in 1972 uniting the American Association of State Highway and Transportation Officials (AASHTO) and Associated General Contractors of America (AGC) committee with the American Road and Transportation Builders Association (ARTBA).  Task Force 13 is the longest standing of all existing subcommittee Task Forces.

Standards are documented agreements containing technical specifications and criteria to be used consistently as rules, guidelines, or definitions to ensure that material, products, processes and services are fit for their purpose.  For example, the construction details of the guardrail barrier common on America's roadside are derived from a 1995 standard "A Guide to Standardized Highway Barrier Hardware."  Adhering to this standard ultimately means that highway barriers will perform consistently from State to State to make roadsides safer for errant vehicles that leave the roadway.  Standards thus contribute to making life simpler, and to increasing the safety, reliability and effectiveness of the goods and services we use.

Roadside Design Guide, 3rd Edition

The Roadside Design Guide is an AASHTO publication that synthesizes current information and operating practices related to roadside safety presented both in metric and U.S. customary units. It focuses on safety treatments that can minimize the likelihood of serious injuries when a motorist leaves the roadway.

Chapters 3 through 9 of the Roadside Design Guide refer to many of the systems available in the online guides offered by Task Force 13. The links below DO NOT point to AASHTO's Roadside Design Guide, but rather to the specific types of systems refered to in those chapters.
