• Abstract:
  A normal bridge approach slab in Louisiana is a reinforced concrete slab. It connects ; the bridge deck to the adjacent paved roadway. Its intended functions are: ; 1. To span the void that may develop below the slab due to soil erosion or ; embankment settlement; ; 2. To minimize slab deflection, which could result in settlement near the abutment; ; 3. To provide a ramp for the differential settlement between the embankment and ; the abutment (this function is affected by the length of the approach slab and the ; magnitude of the differential settlement); and ; 4. To provide a better seal against water percolation and erosion of the ; embankment.
