OBJECTIVES:
KYSPR 10-401
Continuation of an Approved Study
Anticipated Completion FY 2011
I. Conduct a literature review to determine when high-strength quenched & tempered
(Q&T) steels were first employed on bridges in the U. S. Review the evolution of the
ASTl\lIAASHTO standard steels including adoption of fracture-touglUless tests.
Identify previous problems encountered with those steels including low touglUless,
susceptibility to weld cracking and stress corrosion/hydrogen stress cracking.
2. Review the KYTC bridge inventory to identify existing steel bridges that could have
potentially employed high-strength Q&T steels.
3. Review plans/materials lists for the bridges that potentially could possess Q & T steels
and identify any that contained those steels (and the relevant structural members).
4. Perform hardness tests on potential bridges/structural members where documentation
is lacking to determine if they possess Q&T steel.
5. Provide KYTC with a list of bridges containing Q&T steel along with
reconUllendations/guidelines for fo llow-on investigations, inspections and testing to
preclude the presence of defective material or potential problematic detail s/issues.
