FAST/HAL WOOD TIE AND FASTENER EXPERIMENT

Wood ties and fastening systems were installed in two 5-degree curves and in a 6-degree curve and were subjected to 160 MGT of heavy axle load traffic. Comparison of static force and displacement data collected under similar conditions indicates that rail base displacement and rotation values measured during the program are greater than values measured during the 33 kip program. Other results show rail fastened with cut spikes will displace laterally twice as much as rail fastened with elastic fasteners at L/V ratios around 0.5. Fastener failures and maintenance demand were minimal and limited to one fastener type. Tie plate cutting is limited to the field side of the low rail on the 6-degree curve.
