The safety shape portable concrete barrier (PCB) has been approved for use when placed on a bituminous or concrete pad. Construction personnel would like to use PCBs in temporary situations along roadways where the use of a bituminous or concrete pad is impractical and costly. However, when PCBs are placed on soil foundations with no anchorage, they tend to dig into the soil, causing the barrier sections to rotate or overturn. The objective of this research was to develop a device which will allow temporary PCBs placed on soil foundations to translate without significant rotation when impacted by errant vehicles. This device was developed and successfully tested to Test Level 3 of the National Cooperative Highway Research Program (NCHRP) Report No. 350.

Download Evaluation of the Performance of Portable Precast Concrete Traffic Barriers Book in PDF, ePub and Kindle
The portable precast concrete traffic barrier is used to separate high speed vehicular traffic and construction activities. However, since there was a lack of information on the barrier's performance in a construction zone environment, officials of the Virginia Department of Highways and Transportation requested that the Virginia Highway and Transportation Research Council evaluate the performance of the barrier during the widening of the Virginia Beach-Norfolk Expressway (Rte. 44). The scope of the evaluation included (1) a review of the literature on the performance of the concrete "safety shape" barriers, (2) an examination of the accident data before and during construction on Rte. 44 to determine the effects of construction on the frequency and characteristics of traffic accidents, (3) an analysis of tire marks and barrier-involved accidents to determine the effectiveness of the barriers in safely redirecting vehicles, and (4) an examination of the effects of construction on traffic characteristics. The literature review revealed that in using the precast concrete traffic barrier the following factors should be considered: (1) the end of the barrier should never be exposed to oncoming traffic; (2) the barrier joints must be tight for the barriers to act as a system; (3) the longitudinal axis of the barriers should be placed parallel to the roadway, except when the barrier system is started with a flare; (4) the barrier system should have a minimum length of 100 feet (30 m); and (5) the barrier system must have lateral support in order to prevent vehicle penetration. For conditions on Rte. 44, it was found that (1) there was an average of 49 vehicle contacts with the barrier for every reported accident in which the barrier was involved; (2) there was a definite tendency for motorists to stay out of the barrier lane, but avoidance of the barrier lane was reduced as volume increased; and (3) with a 55 mph (88 km/h) posted speed limit, the vehicular speeds were reduced by only a few miles per hour when the barriers were in place. Evaluation of the barrier's performance during the widening of I-95 is recommended, since that highway carries a much higher volume of tractor-trailers than does Rte. 44.

Download Develop Guidelines for Inspection, Repair, and Use of Portable Concrete Barriers Book in PDF, ePub and Kindle
The purpose of the tests reported herein was to assess the performance of the damaged portable concrete barrier according to the safety-performance evaluation guidelines included in the American Association of State Highway and Transportation Officials Manual for Assessing Safety Hardware (MASH), Second Edition. The crash tests were performed in accordance with MASH Test 3-11, which involves a 2270P vehicle weighing 5000 lb impacting the longitudinal barrier while traveling at 62 mi/h and 25 degrees. This report provides details on the damaged portable concrete barriers, the crash tests and results, and the performance assessment of the damaged portable concrete barriers for MASH Test Level 3 (TL-3) longitudinal barrier evaluation criteria. The damaged portable concrete barriers met the performance criteria for MASH TL-3 longitudinal barriers.
