30、d Transportation Officials.All rights reserved. Duplication is a violation of applicable law.| viiPREFACEEffective traffi c barrier systems, end treatments, crash cushions, breakaway devices, truck-mounted attenuators, and other hardware are used to achieve the highest levels of highway safety. New

31、systems are continually emerging to address safety problems, and traditional devices and practices for their use are being improved in response to an increased understanding of safety performance, a changing vehicle fl eet, the emergence of new materials, and other factors. Full-scale crash testing

32、has been and will continue to be the most common method of evaluating the impact performance of safety hard-ware. Because many agencies conduct such tests, there is a need for uniformity in the procedures and criteria used to evaluate traffi c barriers and other roadside safety features. Procedures

33、for full-scale vehicle crash testing of guardrails were fi rst published in the Transportation Research Board (TRB) Highway Research Correlation Services Circular 482 in 1962. This one-page document specifi ed vehicle mass, impact speed, and approach angle for the crash tests. In 1974, the National

34、Cooperative Highway Research Program (NCHRP) Report 153: Recommended Procedures for Vehicle Crash Testing of Highway Appurtenances was published to address questions that were not covered in Circular 482. This 16-page document provided a more complete set of testing proce-dures. Transportation Resea

35、rch Circular 191, published in 1978, addressed minor changes needed to address particular problem areas in NCHRP Report 153. In 1980, National Cooperative Highway Research Program (NCHRP) Report 230: Recommended Procedures for the Safety Performance Evaluation of Highway Safety Appurtenances was pub

36、lished to broaden the scope of NCHRP Report 153. This 36-page document incorporated new procedures, updated the evaluation criteria, and brought the procedures up to date with available technology and practices. This document served as the primary reference for full-scale crash testing of highway sa

37、fety appurtenances in the U.S. and in many other parts of the world.During the subsequent decade, the evolution of roadside safety concepts, technology, and practices necessitated an update to NCHRP Report 230. Reasons included signifi cant changes in the vehicle fl eet, the emergence of new barrier

38、 designs, increased interest in matching safety performance to levels of roadway utilization, and advances in computer simulation and other evaluation methods. The resulting document, National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance

39、Evaluation of Highway Features, was published in 1993. The AASHTO Manual for Assessing Safety Hardware (MASH), 2009, is an update to and supersedes NCHRP Report 350 for the purposes of evaluating new safety hardware devices. This publication marks the fi rst time that AASHTO has offi cially adopted

40、crash-testing procedures for use in assessing roadside hardware. Previous editions were published as research reports from TRB and NCHRP. In addition, it should be noted that MASH does not supersede any guidelines for the design of roadside safety hardware, which are contained within the AASHTO Road

Duplication is a violation of applicable law.viii | Manual for Assessing Safety HardwareMASH was developed through NCHRP Project 22-14(02), “Improvement of Procedures for the Safety

42、-Performance Evaluation of Roadside Features,” and contains revised criteria for impact per-formance evaluation of virtually all highway safety features. Updates to MASH include increases in the size of several test vehicles to better match the current vehicle fl eet, changes to the number and impac

43、t conditions of the test matrices, and more objective, quantitative evaluation criteria.An implementation plan for MASH that was adopted jointly by AASHTO and FHWA states that all highway safety hardware accepted prior to the adoption of MASH using criteria contained in NCHRP Report 350 may remain i

44、n place and may continue to be manufactured and installed. In addition, highway safety hardware accepted using NCHRP Report 350 criteria is not required to be retested using MASH criteria. However, new highway safety hardware not previously evaluated must utilize MASH for testing and evaluation. 200
