Available in PDF, EPUB and Kindle. Book excerpt: Differential settlement at the roadway/bridge interface typically results in an abrupt grade change, causing driver discomfort, impairing driver safety, and exerting potentially excessive impact traffic loading on the abutment. Bridge approach slabs are used to keep the effects of this differential settlement within tolerable limits. In many cases, however, the final magnitude of settlement exceeds the working range of an approach slab, necessitating costly roadway and slab repairs. Many state DOTs regard the settlement of bridge approach slabs as a substantial maintenance problem. Guidelines affecting the use, design methodology, material specifications, and construction techniques vary greatly from state to state. The purpose of this study was to provide a literature review on the subject and to conduct a survey on the state of the practice. Thirty-nine state DOTs responded to the survey. Summary findings were compiled, and a comparison with current VDOT practices was made. Recommendations for a new set of guidelines, aimed at mitigating bridge approach settlement, were formulated.

This book was released on 2005 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area, regardless of pavement type, has been the cause of poor riding quality. Most problems occurring at bridge approaches can be associated with differential settlement between the highway pavement and bridge deck, rotation and/or lateral movement of the abutment, and poor design of structural components. This report compiles the different problems that have been encountered at approaches to bridges and summarizes corrective measures that have been used or recommended. Based on extensive finite element investigations, a comprehensive literature review, and a survey of state highway agencies, the report makes recommendations on approach slabs, drainage systems, approach embankments, and the use of geotextiles. Different approach slab lengths based on fill heights and assuming granular backfill material are recommended. Points regarding the special attention that must be given to controlling and driving water away from critical areas around abutments summarized. The use of marginal materials and/or inadequate compaction at approach recommendations on materials, compaction, and construction for approach embankments. The study reviewed the use of geotextiles, a technique that is promising, but requires further study to obtain more information on their in-place behavior.
