ABSTRACT
Two full-scale vehicle crash tests were conducted on the Iowa Box-Aluminum Bridge Rail. Test I1-1 was conducted with an 1800 lb. vehicle at 15 deg. and 60 mph. Test I1-2 was conducted with a 4310 lb. vehicle at 25 deg. and 60 mph. The Iowa Box-Aluminum Bridge Rail contained two rail splices. Each splice was 26 ft.-6 in. from the rail post on each end. The point of impact for Test I1-1 was directly at a splice. The point of impact for Test I1-2 was directly at the midpoint of the span that contained the second splice. The tests were evaluated according to the safety criteria in NCHRP 230. The safety performance of the Iowa Box-Aluminum Bridge Rail was determined to be unsatisfactory.
