This structural drawing is the APPROACH SLAB detail design given in the AutoCAD 2D drawing. The approach slab acts as a transition between the bridge and the road pavement. The segment of the embankment directly behind the abutment/back wall that was dug to build the abutment/back wall is spanned by the approach slab, which serves as an intermediate bridge. For more knowledge and detailed information download the AutoCAD 2D dwg file.
