Download or read book An Overview of Mitigation Strategies for Settlements Under Bridge Approach Slabs written by Raja Veerendra Yenigalla and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Settlement and heave related movements of bridge approach slabs relative to bridge decks create a bump in the roadway causing inconvenience to the travelling public and at times so large as to make travelling unsafe. Hence, it is important to adopt suitable remedial methods to mitigate the approach settlements so as to ensure safe traveling conditions and also to decrease the repair/maintenance costs. This thesis presents an overview of a few case studies on different mitigation techniques applied on bridge approach settlement problems at various locations in the state of Texas. The methods employed to mitigate the settlement including Polyurethane injection, soil nailing, and potential utilization of Geofoam and flowable fill are discussed. Also, the development of design charts for the construction of light weight fill embankments using Expanded Clay and Shale (ECS) aggregate material is presented. Methods on how to use the design charts for various embankments are also covered.

This book was released on 2012 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 [i.e., casualties], 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.

Available in PDF, EPUB and Kindle. Book excerpt: The design changes in the 1990s to bridge approaches resulted in approach slabs of about 8m in length supported at one end on the bridge abutment and at the other by a sleeper beam resting on the embankment. These slabs have not performed adequately due primarily to excessive deformation of the foundation and fill soils under the slab and sleeper beam. Survey questionnaires were administered for resident engineers in MoDOT and neighboring states to assess overall performance. Two bridge sites were selected for more detailed study of the deformation mechanisms. Analyses involving modeling using a finite element method program were conducted using soil properties obtained from drilling, sampling and laboratory testing at the study sites. Conclusions and recommendations are in the following categories: initiating programmatic instrumentation and monitoring plans for approach embankments; enhanced drilling, sampling and analysis at locations of future embankments; geosynthetic reinforcement of the embankment; staged construction; separating grading and paving contract; abutment and drainage details; and improved compaction specifications.

Download or read book Settlement Issues -- Bridge Approach Slabs (final Report Phase 1) written by Lary R. Lenke and published by . This book was released on 2006 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New Mexico Department of Transportation (NMDOT) Bridge Section in conjunction with various NMDOT district engineers have documented settlement issues with bridge approach slabs, i.e., the ubiquitous "bump at the end of the bridge," as a pressing maintenance, safety, construction and design issue. A literature review identifies geotechnical issues with the natural soil foundation and the embankments as the leading contributor to "the bump." A field evaluation of 19 New Mexico bridges suggest that most, if not all, bump problems in the state are associated with geotechnical issues. The lengths of approach slabs in New Mexico are deemed too short. Recommendations for dealing with "the bump" are thorough geotechnical analysis and engineering implementation of this analysis in the design and construction of the natural soil foundation and embankment materials. High quality QA/QC (quality assurance-quality control) is absolutely required. Lengthening of approach slabs is also recommended.
