Research on shear strength and fatigue characteristics of bridge deck pavement bonding layers

Big span bridge has become more and more while the configuration become very innovative as pavement traffic development in China especially cement concrete bridge. Therefore the bridge deck pavement bonding layers are emphasized much more as an important part of bridge traffic system, which can mitigate travel impact to bridge and magnify stationary or traffic amenity. The quality and durability of deck pavement bonding layer has directly effect on traffic safety, comfort, durability and investment of bridge. In real project, many early age damage of bridge deck pavement has become serious disease that affecting the function of bridge and arosing traffic problems. In this paper UTM-25 was used to test the shear strength and fatigue life of bridge deck pavement bonding layers.
