• Abstract:
  In 2003, Engineered Materials of Maine (EMM, Bangor, Maine) fabricated forty-eight (48) 8-inch wide, 10-inch deep, 12-foot long Advanced Engineered Lumber (AEL) mixed hardwood glue-laminated (glulam) railroad bridge ties. Over a two day period in September of 2005 the AEL ties were installed on the east span of the New Meadows railroad bridge as shown in Figure 1. During the same time period, the solid sawn 8-inch wide, 10-inch deep southern yellow pine ties were installed on the remaining three spans. On June 7, 2007 the AEL ties were visually inspected by Olivia Sanchez (AEWC Center, UM), Brian Marquis (MDOT) and George Jackman (MDOT, Railroad Division). Overall, the ties remain in fair condition, with the ties showing face bonding delamination along the overhang portion of the ties, as well as longitudinal cracks along the top lamination.
