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 potentially causing injuries or even casualties, lowered perception of TxDOT's road works, increased maintenance work, and constant delays to rehabilitate the distressed lanes at a cost of $7 million dollars annually to repair them. All these make this bump issue a major maintenance problem in Texas. Several mitigation methods have been employed and the results are not always satisfactory. Hence, there is an important research need to better understand mitigation technologies and then develop and evaluate technologies to reduce bumps for bridge approaches in Texas. Researchers from UTA and UTEP propose two phases to accomplish the research. The first phase is to compile the available documented information that covers various methods used for approach settlement mitigation technologies along with a few recommendations for new and proven technologies that need to be researched in the field environment. The second and final phase will focus on field evaluation of selected methods in producing approach slabs with no bumps. The final deliverables will include two products summarizing syntheses, available best practices, design and construction specifications and cost-benefit studies along with a research report summarizing research findings.
