A recent transportation technology report outlines a study that has evaluated five different types of bridge deck fasteners used in the United States and Canada. This article describes that study which involves the mechanical description of each of the five systems, their heavy-axle-load (HAL) capacity in millions of gross tons (mgt), and what types of problems may be found in each sort. The most effective system with regard to HAL capacity and amount of maintenance (i.e. no maintenance and 460 mgt capacity) involved two nuts and a thread locking material. The least effective system in these terms uses a lock nut and a spring lock washer, which only withstood 30 mgt of HAL before requiring maintenance.
