• Abstract:
  Settlement and heave related movements of bridge approach slabs relative to bridge decks create a bump in ; the roadway. Several problems arise from these bumps, which include poor riding conditions, potential ; vehicle damage, loss of vehicle control causing injuries or even casualities, lowered perception of the ; department’s road works, increased maintenance works, and constant delays to rehabilitate the distressed ; lanes. All these make this bump problem a major maintenance problem in Texas. Several mitigation methods ; have been employed, and the results are not always satisfactory. In the present research, two treatment ; methods are investigated for controlling settlements of approach slabs of new bridge construction. ; Researchers from UTA and UTEP performed two phases to accomplish these studies. During the first phase, ; the documented information that covers various methods used so far for approach slab settlement mitigation ; technologies is compiled and presented. The second and final phase focused on field evaluation studies of ; deep soil mixing and light weight embankment fill treatment methods in reducing settlements. A few other ; technologies were also evaluated for reducing settlements of existing bridge approach slabs. Both design and ; construction specifications of the new methods that provided effective treatments in field conditions are ; presented.
