Static Fatigue Experimental Research on Orthotropic Deck with Composite Pavement Layer

Abstract:

The experimental results show that the deck of the bridge displays obviously orthotropic features; shear nails with reasonable density can increase the binding capability of each part of deck pavement and overall mechanical performance. The results of fatigue test on the two groups of specimen indicate that the composite deck pavement added with the shear nails and the transition layer of steel fiber concrete has no sign of fatigue failure after 8.3 million fatigue loading tests, and its fatigue resisting property is obviously better than the deck pavement where the asphalt concrete is directly paved on the surface of deck, that is to say the service life of the deck pavement can be extended by the use of steel fiber concrete layer.
