ABSTRACT

Other agencies use a reinforced concrete slab because they believe the rigid approach slab is successful in preventing the bridge approach settlement (Wahls, 1990). In this case, one end of the slab is connected to the main structure by two methods. e rst option connects the slab directly to the bridge deck by extending the main reinforcement from the bridge deck to the approach slab. e second option connects the approach slab to the abutment by using a dowel/tie bar (White et al., 2005).
