Book Vehicle Crash Tests of the Type 80 Bridge Rail

Download or read book Vehicle Crash Tests of the Type 80 Bridge Rail written by Robert Meline and published by . This book was released on 1999 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Vehicular Crash Tests of the California ST 20 Bridge Rail

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.

Book Vehicle Crash Tests of the Type 70 Bridge Rail

Download or read book Vehicle Crash Tests of the Type 70 Bridge Rail written by Robert Meline and published by . This book was released on 1998 with total page 90 pages. 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.

Book Vehicle Crash Tests of Steel Bridge Barrier Rail Systems for Use on Secondary Highways

Download or read book Vehicle Crash Tests of Steel Bridge Barrier Rail Systems for Use on Secondary Highways written by John Jewell and published by . 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.

Book Full scale 1 800 Lb Vehicle Crash Test on the Iowa W beam Approach Guardrail to the Concrete Safety Shape Bridge Rail

Download or read book Full scale 1 800 Lb Vehicle Crash Test on the Iowa W beam Approach Guardrail to the Concrete Safety Shape Bridge Rail written by Brian G. Pfeifer and published by . This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A second full-scale vehicle crash test was conducted on the Iowa W-Beam Approach Guardrail Transition Section to the Concrete Safety Shape Bridge Rail. Test I6-2 was conducted with an 1,840 lb. vehicle at 22.0 degrees and 64.5 mph. This installation has been previously evaluated with a 5,400 lb. vehicle. The overall test length of the installation was 64 ft.-6 3/4 in. The installation consisted of four major components: (1) concrete safety shape, bridge rail end-section, (2) the w-beam approach guardrail section, (3) the w-beam breakaway end anchorage, and (4) the w-beam terminal connector. The concrete end-section was 7 ft. long and 2 ft.-8 in. high. A 6-in. concrete curb was constructed 13 ft. beyond the end of the concrete end-section. The w-beam approach guardrail section consisted of 62 ft. - 6 in. of 12 gague standard w-beam. The top of the w-beam was installed at a mounting height of 27-in. The w-beam was supported by 13 timber posts. The design consisted of three 10-in. by 10-in. posts, eight 8-in. by 8-in. posts, and two 6-in. by 8-in. posts. The post spacing between post 1 through 7 and 7 through 13 as 3 ft. - 1 1/2 in. and 6 ft. - 3 in., respectively. The point of impact was 15 ft. upstream from the end of the concrete end-section between posts 5 and 6. The test was evaluated according to the safety criteria in AASHTO guide specifications. The safety performance of the Iowa W-Beam Approach Guardrail Transition Section was determined to be satisfactory.
