~ Eliminating the anchor assembly did not yield significant cost savings.
~ Use of elastomeric bearing pads in integral abutments does not provide a means for field adjustment of girder seats.
~ For interior bents, Structure Design should consider use of disc bearings in lieu of pot bearings.
~ Use of disc bearings will not yield cost savings, but they are simpler bearings with fewer pieces and parts.
~ Access conditions at integral abutment bridge sites may necessitate construction of the reinforced approach fill prior to setting the girders.
~ Design of the approach fill would be based on crane loads which are unknown during bridge design phase, and it would also serve as formwork for the integral abutment diaphragm.
~ Drip beads were not utilized.
~ Culvert inspection issues were discussed, and it was noted that culverts with spans greater than 20 ft. should be documented in the bridge inventory system.
A/I ~ Structure Design will investigate standardizing disc bearings with a goal of increasing their use.
A/I ~ Structure Design will discuss construction of reinforced approach fills for integral abutment bridges at the AGC-DOT Joint Bridge Design Committee meeting.
A/I ~ Structure Design will let a trial integral abutment bridge with the approach fill to be constructed prior to setting girders.
A/I ~ Structure Design will review other States' practices on drip beads and sources such as Mid- Atlantic SCEF and TRB's bridgeaesthetics.org web site.
A/I ~ Bridge Management will investigate the feasibility of documenting culverts with spans over 20 ft. in the bridge inventory system.
