Chapter 12: Guidelines for Crash Cushions & Barrier End Treatments

Chapter 12 Barriers, Crash Cushions and BarrierEnd Treatments IntroducƟon Safety appurtenances are an integral part of a roadway. They are placed on the roadway to protect an errant vehicle from leaving the roadway and entering a more serious hazard. Barrier systems, crash cushions and end treatments systems have been designed so occupants of the errant vehicle sustain a minimal amount of injury when impacted. Barrier systems can be placed on shoulders, which are typically to prevent a vehicle from entering a hazard, or in a median which may be to protect a vehicle from entering a hazard or to protect from crossover incidents. Crash cushion are safety appurtenances designed to protect hazards as standalone system or to protect the ends of barrier when bidirec onal traﬃc is present. Crash cushion may or may not have a specified length of need associated with the system. Barrier End Treatments are designed or to protect an errant vehicle from impac ng a barrier end, and to provide an acceptable ride down from the impact forces. Barrier End Treatments are single sided systems and are used in applica on of direc onal traﬃc. Used on approach ends of barriers and on trailing ends of barriers when the trailing end is within the minimum AASHTO clear zone. Barrier End Treatments will a specified barrier length of need associated with the installa on. All barrier systems, crash cushions, and end treatments have been approved based on crash tes ng conducted by, over scene by the Federal Highway Administra on or by a specific manufacturer who produce a proprietary system. All barrier systems, crash cushions and end treatments used on Utah Highways and are under the jurisdic on of UDOT meet the test requirements of NCHRP 350 Recommended Procedures for Safety Performance Evalua on of Highway Features or the AASHTO document Manual for Assessing Safety Hardware (MASH), and a le er of acceptance has been issued by the Federal Highway Administra on. The Guidelines for Cash Cushions and End Treatments and Approved Products List, intended as a guide for a designer, would be a valuable tool for an inspector to use as a reference and is available on line.

CHAPTER 12 Barrier SelecƟon Process Roadside Barrier ApplicaƟons Before a roadside barrier is designated for a project the designer should be evalua ng the project for barrier based on speed, accident history, hazards and roadway alignment. Where realignment is prac cal then that should be the first op on, if a hazard is present removal of the hazard, if possible, is the best solu on. If through analyses a barrier is warranted the type of barrier to be installed should have input from local maintenance personnel. Median Barrier ApplicaƟons Median Barrier is typically installed to prevent crossover accidents. As with roadside barrier there are warrants that should be met prior to installa on. UDOT developed and adopted a Median Barrier Selec on Process. This process guides the designer through the analyses of warran ng a median barrier, that analyses includes median width, speed, and crash history. The type of barrier selected also goes through an analyses before being designated for a project. The analyses includes but not limited to, expected life cycle cost, roadway geometrics and ADDT with an emphasis on heavy truck volumes. Special Barrier ApplicaƟon In 2012 UDOT approved Standard Drawing BA 1E which requires a TL-5 concrete barrier be placed to protect all bridge columns which fall within the maximum required AASHTO Clear Zone as established in the current edi on of the AASHTO Roadside Design Guide.

CHAPTER 12

12.2 Crash Cushions and Barrier End Treatments Crash Cushions and end treatments are devices designed, manufactured and installed to protect the occupants of an errant vehicle from excessive impact forces that would occur from hi ng a fix object or blunt end of a barrier system. Protec on of these types of hazard contribute to safe use of the facility both during work and a er project is complete. There are a variety of diﬀerent systems approved for use under varying condi ons. It is important that the design and installa on of manufacturer cer fied components are followed to ensure that the system performs its intended func on in case of impact. Crash cushions and end treatments are constructed according to manufacturer’s specifica ons. Systems are selected by the designer using UDOT Guidelines for Crash Cushions and Barrier End Treatments and CC Standard Drawings. The Guidelines for Cash Cushions and End Treatments and Approved Products List, intended as a guide for the designer, would be a valuable tool for an inspector to use as a reference and is available on line. h p://www.udot.utah.gov/main/uconowner.gf?n=9083308252097033 Approved crash cushions and barrier end treatments are all proprietary tems. Installa on contractors are required to be trained and cer fied by the individual manufacturers prior to installing. A trained installer must be an ac ve par cipant during the installa on of a system.

A) Crash Cushions – SecƟon 02843 All crash cushions have passed NCHRP 350 or MASH tes ng criteria. Table 12.2 below shows how these system are categorized for use. The informa on in the chart is general in nature, to get full documenta on of the systems see UDOT’s Guidelines for Crash Cushions and Barrier End Treatments. UDOT has accepted TL-3 as the standard for high speed roadways (>55 MPH). Many of the crash cushion can be configured for various speed and it is acceptable to allow for this configura on when the design speed is less than TL-3 requirements. Many of the crash cushion systems have also been tested at speeds greater than the TL-3 requirements, but FHWA and UDOT do not require systems to be configure for speeds higher than TL-3 requirements, 62 MPH (100 KM).
