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.
