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.

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.
