This report presents a potential framework for a National Bridge Maintenance Database (NBMD). This framework provides a uniform format for collecting, reporting, and storing information on bridge maintenance actions. Use of this framework will promote compatibility of maintenance data reported by different agencies and will provide an effective means for using these data in evaluating cost and performance of alternative maintenance applications or as a basis for cost-benefit analysis and evaluation of cost and deterioration models. The material contained in the report should be of immediate interest to state bridge and maintenance engineers and others concerned with the maintenance and management of bridges.

Development of a Precast Bent Cap System for Seismic Regions
Author: Restrepo, Jose I | Size: 7.76 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 114 | ISBN: 9780309155335
This report develops and validates precast concrete bent cap systems for use throughout the nation's seismic regions. The report also includes a series of recommended updates to the AASHTO "LRFD Bridge Design Specifications," "Guide Specification for LRFD Seismic Bridge Design," and AASHTO "LRFD Bridge Construction Specifications" that will provide safe and reliable seismic resistance in a cost-effective, durable, and constructible manner. The material in this report will be of immediate interest to bridge engineers.

This report presents recommendations for (1) a predictive equation for equilibrium local scour and (2) a potential equation for predicting scour evolution rates at wide piers and skewed piers. These equations provide better estimates of local scour and scour evolution rates than those predicted by currently available equations. Such estimates will reduce over-predictions and the unwarranted need for countermeasures. The material contained in the report should be of immediate interest to state hydraulic engineers and others involved in the design, operation, and maintenance of highway bridges.

This report presents design guidelines for concrete girders strengthened in shear using externally bonded Fiber-Reinforced Polymer (FRP) systems. These guidelines address the strengthening schemes and application of the FRP systems and their contribution to shear capacity of reinforced and prestressed concrete girders. The guidelines are supplemented by design examples to illustrate their use for concrete beams strengthened with different FRP systems. The guidelines are presented in AASHTO LRFD format to facilitate use and incorporation into the AASHTO "LRFD Bridge Design Specifications." Also, the report presents recommended changes to the AASHTO "LRFD Bridge Design Specifications" to introduce provisions pertaining to the use of FRP systems for strengthening concrete girders in shear. The material contained in the report should be of immediate interest to state bridge engineers and those involved in the strengthening and repair of concrete structures using FRP systems.

This report provides an evaluation of existing "AASHTO LRFD Bridge Design Specifications" relevant to the use of high-strength reinforcing steel and other grades of reinforcing steel having no discernible yield plateau. The report also includes recommended language to the "AASHTO LRFD Bridge Design Specifications" that will permit the use of high-strength reinforcing steel with specified yield strengths not greater than 100 ksi. The material in this report will be of immediate interest to bridge engineers.

This report provides guidelines for ramp and interchange spacing based on design, operations, safety, and signing considerations. The guidelines will be valuable to transportation agencies who need to balance system efficiency and safety with the need to provide access for local users. The guidelines are intended to aid the decision-making process when an agency is considering new ramps or interchanges on existing facilities, modifying ramps and interchanges of existing facilities, or when planning and designing new highway and interchange facilities. The guidelines also offer standardized definitions measuring ramp and interchange spacing, which have varied in previous design manuals guides.

This report provides a set of protocols and methodologies for using available recent truck traffic data to develop and calibrate vehicular loads for load and resistance factor design (LRFD) superstructure design, fatigue design, deck design, and design for overload permits. The protocols are geared to address the collection, processing, and use of national weigh-in-motion (WIM) data. The report also gives practical examples of implementing these protocols with recent national WIM data drawn from states/sites around the country with different traffic exposures, load spectra, and truck configurations. The material in this report will be of immediate interest to bridge engineers. This report replaces NCHRP Web Document 135.
