Longitudinal wheel timbers. Flexing tests on laminated timbers (Including screw extraction tests) (TM-CES-55)

Some 5 to 6 years ago, the possible use of fabricated laminated timbers in place of solid longitudinal wheel timbers on bridges, was considered. The Research and Development Division carried out mechanical flexing (and other sundry) tests on 2 samples of laminated timbers, one of which, known as "MICROLAM", has...
