Book Description: Bridge approach settlement and the formation of the bump is a common problem in Iowa that draws upon considerable resources for maintenance and creates a negative perception in the minds of transportation users. This research study was undertaken to investigate bridge approach problems and develop new concepts for design, construction, and maintenance that will reduce this costly problem. As a result of the research described in this report, the following changes are suggested for implementation on a pilot test basis: Use porous backfill behind the abutment and/or geocomposite drainage systems to improve drainage capacity and reduce erosion around the abutment; On a pilot basis, connect the approach slab to the bridge abutment, change the expansion joint at the bridge to a construction joint of 2 in., use a more effective joint sealing system at the CF joint, and change the abutment wall rebar from #5 to #7 for non-integral abutments; and For bridges with soft foundation or embankment soils, implement practices of better compaction, preloading, ground improvement, soil removal and replacement, or soil reinforcement that reduce time-dependent post construction settlements.

Book Description: Over 140 experts, 14 countries, and 89 chapters are represented in the second edition of the Bridge Engineering Handbook. This extensive collection highlights bridge engineering specimens from around the world, contains detailed information on bridge engineering, and thoroughly explains the concepts and practical applications surrounding the subject. Published in five books: Fundamentals, Superstructure Design, Substructure Design, Seismic Design, and Construction and Maintenance, this new edition provides numerous worked-out examples that give readers step-by-step design procedures, includes contributions by leading experts from around the world in their respective areas of bridge engineering, contains 26 completely new chapters, and updates most other chapters. It offers design concepts, specifications, and practice, as well as the various types of bridges. The text includes over 2,500 tables, charts, illustrations, and photos. The book covers new, innovative and traditional methods and practices; explores rehabilitation, retrofit, and maintenance; and examines seismic design and building materials. The second book, Superstructure Design, contains 19 chapters, and covers information on how to design all types of bridges. What’s New in the Second Edition: Includes two new chapters: Extradosed Bridges and Stress Ribbon Pedestrian Bridges Updates the Prestressed Concrete Girder Bridges chapter and rewrites it as two chapters: Precast/Pretensioned Concrete Girder Bridges and Cast-In-Place Post-Tensioned Prestressed Concrete Girder Bridges Expands the chapter on Bridge Decks and Approach Slabs and divides it into two chapters: Concrete Decks and Approach Slabs Rewrites seven chapters: Segmental Concrete Bridges, Composite Steel I-Girder Bridges, Composite Steel Box Girder Bridges, Arch Bridges, Cable-Stayed Bridges, Orthotropic Steel Decks, and Railings This text is an ideal reference for practicing bridge engineers and consultants (design, construction, maintenance), and can also be used as a reference for students in bridge engineering courses.

Book Description: This volume presents the second half of a diverse collection of chapters in the field of materials and infrastructures in transport systems, which illustrate the technological and methodological innovations required to rise to the challenge of building more sustainable transport infrastructures for the future. The authors explore the potential of these sustainable solutions to improve the performance and efficiency of materials and infrastructures, with a reduced environmental impact and lower cost. Theoretical and practical case studies address a variety of topics including circular economy and sustainability, the impacts of climate change, durability, lifecycle, auscultation and the monitoring of infrastructures. This book provides transport researchers and professionals with a better understanding of the current and future trends in these innovative fields, enabling them to put into practice new technologies and methods of design and management, so that new solutions can become current practices to truly improve modern transport systems.

Book Description: The main objective of this research is to correlate the deformation and internal force of the approach slab with the approach embankment settlements and the approach slab parameters such as length and thickness. Finite element analysis was carried out in the present study. This correlation will be used to evaluate the effectiveness of approach slabs and develop guidelines for their structural design. This information will also help determine when settlement controls are necessary. While flat approach slabs may be used for some short span applications, longer span lengths would require very thick slabs. In such cases, ribbed approach slabs (similar to slab-on-beam bridge decks) are proposed in the present study because they provide advantages over the flat slabs. Based on finite element analysis, internal forces and deformations of ribbed slabs were predicted and their designs were conducted. In addition, special studies on a few issues that were not included in the original scope of work were conducted. These special studies including investigating (1) the skew angle effects and the applicability of the developed methodology for right approach slabs to skewed approach slabs; (2) the failure mode/mechanism of the approach slab end and the abutment connection; (3) the applicability of the developed methodology to AASHTO LRFD highway loads; and (4) rating of the developed approach slabs in terms of special trucks.
