An aesthetic, see-through concrete bridge rail, Type 80, was built and tested in accordance with National Cooperative Highway Research Program (NCHRP) Report 350. The Type 80 bridge rail is an 810 mm-tall, reinforced concrete barrier. The rail has 280 mm-high by 1620 mm-long gaps, 230 mm above the bridge deck surface. The barrier tested was 23 m-long and was constructed at the California Department of Transportation (Caltrans) Dynamic Test Facility in West Sacramento, California. A total of three crash tests were conducted under NCHRP Report 350 Test Level 4, one with an 820 kg car, one with a 2000 kg pickup truck and one with an 8000 kg single unit van truck.

Texas Department of Transportation (TXDOT) and Florida Department of Transportation (FDOT) frequently receive requests to provide aesthetically pleasing traffic rails for use on select bridges and roadways. TxDOT, in response to providing context sensitive design alternatives, initiated a project to develop additional aesthetically pleasing rail alternatives. Under a previous TxDOT project, the F411 bridge rail was constructed and crash tested to Test Level 3 (TL-3). The TL-3 test is a 4405-lb (2000 kg) pickup impacting the railing at 25 degrees and 62.2 mi/h (100 krn/h). This test requires both containment and stability, and non-overturning. Since some breakage of the parapet is possible, potential for vehicle snagging is likely. Vehicle snagging can contribute to vehicle instabilities in the redirection sequence and potential rollover. The TxDOT F411 bridge rail contained and redirected the vehicle, which remained upright during and after the collision period. The bridge rail met the required specifications for NCHRP Report 350 test 3-11. The objective of this research is the full-scale crash test and evaluation of the F411 to Test Level 4 (TL-4). The most direct approach for accomplishing the objectives of this task is to perform a full-scale TL-4 crash test of this railing design. The TL-4 vehicle is a single-unit box-van truck impacting the railing at 15 degrees and 49.7 mi/h (80 krn/h). While containment is required, overturning of the vehicle 90 degrees is an acceptable test outcome. The TxDOT F411 bridge rail performed acceptably for NCHRP Report 350 test 4-12. Based on the performance of the F411 bridge rail in the full-scale crash test to TL-4 test conditions, the F411 may be used where containment of 18,000 lb single-unit trucks is desired.

"The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.
