Title:	Evaluation of Bridge Approach Settlement Mitigation Methods
PI:	Sam Helwany Department of Civil Engineering and Mechanics University of Wisconsin-Milwaukee
Project:	Two to five high potential technologies will be evaluated for eliminating the "bump at the end of the bridge." Test sections will include both new and rebuilt bridge approaches. Instrumentation will be installed to make key performance measurements over a period of six years. A cost comparison of the various methods will also be performed.
Task List:	Phase 1 Conduct a critical review of literature and current practices both in Wisconsin and at the National Level. Investigate innovative technologies and assess potential applications and limitations of methods. On the basis of findings from Task 1 and 2, a refined research plan will be developed, which proposes technologies, test sites, and measurements that will be employed in Phase 2. An interim report will be prepared within six months of documenting Tasks 1 through 3. Phase 2 From Task 2, performance measures and associated instrumentation for monitoring the performance of bridge approaches were identified. Build several bridge approaches using the high potential technologies and the proven instrumentation in Year 2001. Provide an interim report of the as-built information. Collect and analyze field data to demonstrate the performance of the test bridge approaches. Provide a final report documenting information from all tasks.
