http://www.virginiadot.org/vtrc/main/online_reports/pdf/17-r20.pdf This is a link to a recently released Virginia Department of Transportation research report, Development of Improved Connection Details for Adjacent Prestressed Member Bridges. The report contains analytical and experimental results on longitudinal joints of precast concrete box beams and voided slabs. Alternate connections were shown to perform better than current designs.
http://apps.trb.org/cmsfeed/trbnetprojectdisplay.asp?projectid=3171 This is a link to a report, that as a part of National Cooperative Highway Research Program (NCHRP) 12-91, proposes revisions to the current debonding provisions for pretensioning strand in the AASHTO LRFD Bridge Design Specifications and the AASHTO LRFD Bridge Construction Specifications as a result of a research study.
http://www.trb.org/Main/Blurbs/176394.aspx This is a link to NCHRP Research Report 850: Applying Risk Analysis, Value Engineering, and Other Innovative Solutions for Project Delivery. The report investigates the state of the art in managing project development and delivery through application of value engineering for transportation projects. Tools and techniques are presented.
http://www.fdot.gov/research/Completed_Proj/Summary_SMO/FDOT-BDV31-977-35-rpt.pdf This is a link to Impedance-Based Detection of Corrosion in Post-Tensioned Cables: Phase 2 from Concept to Application, a report released by the Florida Department of Transportation that quantifies corrosion rates and oxide film thicknesses for ASTM A416 steel in simulated pore solutions and grout. Also, indirect impedance is studied as a nondestructive method of detecting corrosion in posttensioned tendons.
https://bookstore.transportation.org/item_details.aspx?id=3734 This is a link to purchase the recently published AASHTO Guide Design Specifications for Bridge Temporary Works, 2nd Edition. The design specifications reflect the current state of the practice for the design and construction of falsework, formwork, and temporary retaining structures and include significant changes to the design loads for falsework.
https://bookstore.transportation.org/item_details.aspx?id=3733 This is a link to purchase the AASHTO Construction Handbook for Bridge Temporary Works, 2nd Edition, developed for use by contractors and construction engineers. This handbook supplements the Guide Design Specifications for Bridge Temporary Works.
