In this research, a W-beam guardrail system was developed for installation with the steel post attached to the top of a low-fill concrete culvert. The guardrail system was constructed with a 2.66-mm (12-gauge) thick W-beam rail totaling 53.34 m in length. The post spacing was 1,905-mm on center for post numbers 1-9 and 33-41, while the post spacing for post numbers 9-33 was 952.5-mm on center. Two full-scale vehicle crash tests, using 3/4 ton pickup trucks, were performed on the W-beam guardrail system.

Download Development of a Plan for Compliance with NCHRP 350 for Temporary Concrete Barriers Book in PDF, ePub and Kindle
The Federal Highway Administration has mandated that temporary concrete barriers (TCBs) used on federally funded projects on the National Highway System advertised after October 1, 2002 shall meet the requirements of National Cooperative Highway Research Program (NCHRP) Report 350. The State's present TCB system design is not approved as meeting the NCHRP 350 requirements, and even with modifications it is not likely to meet those standards. The Arizona Department of Transportation (ADOT) and Arizona industry partners are to evaluate many key factors in the ADOT's effort to develop an NCHRP 350 compliance plan for TCBs. Arizona intends to adopt the most valid non-proprietary TCB design, out of already approved designs, for future use in Arizona.

Download Development of an NCHRP Report 350 TL-3 New Jersey Shape 50-inch Portable Concrete Barrier Book in PDF, ePub and Kindle
For roadside work-zones in areas that have opposing traffic flow, safety is enhanced if the temporary barriers incorporate a "glare-shield" that blocks headlight glare from opposing traffic. Currently-available 32-inch portable concrete barriers require the use of an add-on glare shield attached to the top of the barrier. The add-on glare shields are an extra expense and complicate barrier set-up and handling. An alternative solution was to develop a 50-inch high portable concrete barrier which is tall enough to serve as its own glare-shield. Finite element analysis was used to investigate various barrier shapes and connection schemes to identify a successful crashworthy design that would meet requirments of NCHRP Report 350 Test level 3. A 50-inch portable concrete barrier design was developed based on the results of the finite element analyses and was crash tested at the Transportation Research Center in East Liberty, Ohio. The system successfully met all safety criteria of NCHRP Report 350 and has been approved by the Federal Highway Administration for use on the National Highway System as a test level 3 device.
