MODULAR COMPOSITE BRIDGE

| The Modular Composite Bridge (MCB) Program was a logical follow-up to the successful Composite Army Bridge (CAB) Program. The primary focus of the program was the development of structural bridge joints that would enable modularity and reconfiguration of the composite military bridges. The program culminated with the successful fabrication and testing of two, joined seven-meter (full length ) bridge treadway sections. The joined bridge sections were initially subjected to 1,000 fatigue cycles of 100% Proof Load and then loaded to their ultimate capacity of 166% Proof Load (approximately 750,000 lbs.), surpassing the MCB goal of 150%. This successful demonstration of composite bridge joint technology postures the Army on the path of the development and demonstration of a full-scale protoype composite bridge.
