INTRODUCTION Non-prestressed steel reinforced concrete solid structural slab bridges are commonly used by several Departments of Transportation (DOTs) in the United States. Structurally, a continuous deck slab runs parall
22、el to the longitudinal axis of the bridge, and is supported by the abutments at the ends and piers at intermediate locations. The decks typically are between 11 inch (280 mm) and 27 inch (685 mm) in thickness. One of the primary factors affecting concrete bridge durability is deck cracking. Cracks a
23、re caused primarily by low tensile strength of the concrete, volumetric instability, and/or deleterious chemical reactions. Crack openings and spacing are affected by bar size and the effective concrete area surrounding the bar (Soltani et al. 2013). Regardless of the causes, cracking on bridge deck
24、s is a serious concern, because cracks provide access to harmful, corrosive chemicals that deteriorate the reinforcing steel embedded within the concrete. Once chloride and other corrosive agents penetrate concrete, corrosion of the embedded steel can initiate and cause concrete spalling. Such deter
