Integral Bridge Abutment to Approach Slab Connection
This paper presents the findings of a performance investigation of two approach slabs (a cast-in-place slab and a precast panel slab) integrally connected to two parallel bridges. The goal of using the integral connection is to eliminate the bump at the end of the bridge. To measure the performance, a long-term structural monitoring system consisting of various vibrating wire transducers was installed. From the year-long monitoring, the following general conclusions were made: (1) the integral connection functions well, with no observed distress or relative movement between the approach slab and bridge; (2) most of the force at the integral connection is induced by forces at the pavement/approach slab expansion joint; and (3) the observed responses generally followed an annual cycle, with short-term ratcheting patterns also apparent.
