Abstract:

The objective of this project was to test aesthetic bridge rails for park roads, parkways, and other roads under Federal jurisdiction. Four designs were analyzed and evaluated: the Modified (Kansas Corral bridge rail, the Forest Service glulam bridge rail, the Natchez Trace bridge rail, and the aluminum tri-rail bridge rail with sidewalk. Two designs were tested and evaluated: the Forest Service glulam bridge rail end the Modified Kansas Corral bridge rail. Two full-scale crash tests were conducted with each design. The Forest Service glulam bridge raft and the Modified Kansas Corral bridge rail passed both small sedan and pickup truck full-scale tests. Vehicle behavior during and after impact was, In all cases, acceptable. Computer simulation on the Modified Kansas Corral bridge rail and the Natchez Trace bridge rail indicated that the vehicle would be redirected with no vaulting. The Aluminum Tri-Rail bridge rail has a high snagging potential. Both the Modified (Kansas Corral and Natchez Trace designs should be submitted for certification as acceptable for use on Federal Lands highways, including Indian Reservation roads, National Park roads and parkways. and forest highways. Based on the analyses conducted, the Natchez Trace bridge rail should be tested in Its current design to Performance Level 1 of the 1989 AASHTO guide specifications. The Aluminum Tri-Rail bridge rail should be modified and submitted for full-scale testing to Performance Level 1.
