B. Problem Statement
In recent years, substructure repair of bridges has become
increasingly common in New York, largely because of the presence of
soluble chlorides from winter deicing salts. These chlorides from
leaking joints and road spray penetrate substructure elements,
resulting in corrosion, delamination, and spalling. Conventional
concrete (and in some cases shotcrete) is used for repair of larger
distressed areas. Concrete patching materials, including various
types of vertical patching mixes and concrete with super-
plasticizers, are used in smaller areas. Shrinkage cracking and
debonding of all these materials have been reported.
C. Objective
A literature search will be conducted to identify any ongoing
projects in New York and other states with similar climate and
highway conditions that may be relevant to this project. The
objective is to develop improved methods and/or materials for
substructure repairs, with special attention to the impact of
cracking on repairs. This study will help develop. greater
understanding of the performance of current repair methods, as well
as improved materials and/or methods.

D. Background
Maintenance and repair of substructure elements can be complex,
time—consuming, and costly. Numerous techniques have been used
with varying degrees of success. This project will consider all
types of maintenance and repair work on bridge substructures, and
report on techniques, materials, and their effectiveness.
E. Benefits
The work is directly applicable to New York’s needs, and may also
prove beneficial to other states with similar climate and highway
conditions. The final report will include an evaluation of New
York’s current practices and materials, as well as a survey of
repairs on New York bridges.
F. Implementation
New or improved methods and/or materials for substructure repairs
will be implemented by the Highway Maintenance Division. In the
event that new methods or materials are identified, the Materials
Bureau will revise specifications and issue a new list of approved
materials.
G. Work Plan
A literature search of various types of products and techniques
used in New York and other states will be conducted and reviewed.
Current practices for repair of substructure concrete include
conventional concrete, shotcrete, and concrete patching materials,
including various types of vertical patching materials and concrete
with superplasticizers. Surveys will be conducted to determine the
adequacy of current repair procedures, especially the impact of
cracking on those repairs. Data collected in the field will be
statistically analyzed, with results and recommendations published
in a final report. This project is expected to last about 24
months.
H. Report
A report will be prepared to document field evaluations, results,
and conclusions. It will be published and the information made
available to the Department, FHWA, and other interested agencies.
