Samenvatting
Thrie-beam corrugated steel rail was tested as a single rail upgrading for discontinuous bridge rail panels, and as a guiderail and double faced median barrier on posts. Tests were performed to determine rail deflection characteristics, structural adequacy, vehicle decelerations, and vehicle damage. As a guiderail or median barrier the thrie-beam appears to be suitable as a longitudinal barrier, based on tests with 2250-5500 lb vehicles.
