Available in PDF, EPUB and Kindle. Book excerpt: A bridge rail Type 70 was built and tested in accordance with NCHRP Report 350. The Type 70 bridge rail is an 810 mm tall concrete barrier with a sloping face of 9.1 deg from the vertical. The barrier tested was 22.9 m long and was constructed at the Caltrans Dynamic Test Facility in West Sacramento, California. A total of four crash tests were conducted under NCHRP Report 350 test level 4, one with an 820 kg car, two with 2000 kg pickup trucks and one with an 8000 kg van truck. Both the 820 kg and the 8000 kg tests were within the limits of NCHRP Report 350 guidelines.

Download or read book Vehicular Crash Tests of the California ST 20 Bridge Rail written by John Russell Jewell and published by . This book was released on 2004 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the course of this project a see-through steel bridge rail (Type California ST-20) was developed and tested. The ST-20, as tested, is at the limits of meeting the NCHRP Report 3501 TL-4 test matrix. The bridge rail also met the requirements established in the AASHTO Bridge Design Specifications for use as a bicycle rail and is considered an aesthetically pleasing see-through bridge rail. The barrier, as tested, uses steel posts at 3-m spacing to support four boxbeam rails and one additional handrail to meet the height requirements for bicycles. Because the ST-20 is based on a TL-4 bridge rail from Wyoming DOT3,4, only Test 4-11 (NCHRP Report 350) was considered necessary.

This book was released on 1993 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of seven vehicle crash tests were performed, three involving a Type 115 bridge rail and four involving a thrie beam bridge rail. Additional static testing was done on five steel bridge rail posts with different types of post stiffeners. The Type 115 bridge rail consisted of two tube steel rails (4x4x0.25 in.) supported off the edge of deck by steel wide flange posts at 8 ft 0 in. spacing. The thrie beam bridge rail consisted of 10 ga. thrie beam panels blocked out and supported on the edge of deck by steel wide flange posts at 6 ft 3 in. spacing. The typical heights for the Type 115 and the thrie beam bridge rails were 30 and 32 in., respectively. There were two impact tests on the Type 115 bridge rail, one on the Type 115 bridge rail transition, two on the thrie beam bridge rail, and two on the thrie beam bridge rail transition.

This book was released on 2011 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book TL 4 Crash Testing of the F411 Bridge Rail written by Dean C. Alberson and published by . This book was released on 2004 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Barrier installations are warranted (or justified) only at highway locations where the consequence of an errant vehicle leaving the roadway is judged to be more hazardous than the impact with the barrier installation. A six degree-of-freedom mathematical model was found to be useful in describing dynamic behavior of a vehicle during impact. Predictions of vehicle and barrier behavior correlated with results obtained from full-scale crash tests. Crash conditions simulated with a computer were used to identify and evaluate vehicle static and dynamic as well as barrier parameters. Vehicle weight, yaw mass moment of inertia, and deformation constant were found to be significant.
