Available in PDF, EPUB and Kindle. Book excerpt: Many Minnesota bridges have older barriers or parapets that met the design code at the time of construction in the 1950s. Many of these bridge barriers no longer meet current strength and performance requirements of NCHRP Report 350 or the Manual for Assessing Safety Hardware (MASH). As the Minnesota Department of Transportation (MnDOT) begins to rehabilitate older existing bridges, a determination needs to be made as to whether the existing older type of barrier can remain in place or if it should be rehabilitated or replaced with a newer style barrier. This research documented the number of bridges in Minnesota that have One-Line Rails and type G, J, and F barriers and when they were built. Evaluations were then performed for both the structural strength and crashworthiness of each type of barrier and recommended guidance and evaluation criteria were developed to determine when an existing barrier should be upgraded or replaced.

This book was released on 1980 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic barriers are roadside hardware of various designs and materials which are intended to protect vehicles from such off-the-road hazards as trees, embankments, ravines, signposts, bridge support pillars or abutments, or other hazards. The National Transportation Safety Board (NTSB) has been concerned with the problem of inadequate traffic barriers for several years. The Safety Board has investigated accidents in which barriers failed, and has made recommendations to the FHWA. Of primary importance among these have been recommendations that the FHWA develop and promulgate mandatory performance standards for traffic barriers. The purpose of such standards would be to require that traffic barrier types be crash-tested to demonstrate their ability to meet a set of established safety criteria. At present, barriers are not required to meet such criteria through crash-testing. The purpose of this report is to review past Safety Board concerns regarding the adequacy of bridge and highway rail systems and to evaluate the FHWA's efforts to develop safer traffic barriers. This study analyzes the results of recent crash-testing sponsored by the FHWA and makes recommendations concerning performance standards for traffic barriers.
