Recommendations for Design, Construction, and Maintenance of Bridge Approach Slabs.

摘要

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 departments 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.
