A track panel (half-crossties and rail) were placed on top of the ballast and vertical loads were applied to the rail at the center crosstie using a manual hydraulic jack reacting off of the top cross beam of the loading frame. Pressure gauges were placed in the ballast to record the crosstie-ballast interaction. Tests were performed in September 2020. <\/p>\n\n\n\n
