Integral abutment bridges are becoming widely accepted for new construction of short to medium
length highway bridges of limited skew. Although they offer an economic alternative to the use of
bearings, integral abutments present their own unique challenges. One area of concern is the
development of passive pressures behind the abutment due to the cyclic loading of the soil during
thermal movement of the superstructure. The challenge of the present work is to present to the

This report, written by Gary S. Wojcik and David R. Fitzjarrald of the University of Albany, describes the field campaign and subsequent data analysis for the Route 30 bridge over the South Chuctanunda Creek in Montgomery County, NY. The two purposes of this work were 1.) to make more detailed measurements of the bridge environment than we have done in the past to better understand the energy budget of a curing concrete bridge and 2.) to provide atmospheric boundary conditions to a model of curing concrete.

This project involved a field campaign and subsequent
data analysis for the Route 30 bridge over the South
Chuctanunda Creek in Montgomery County, NY. The
two purposes of this work were: 1) to make more
detailed measurements of the bridge environment than
we have done in the past to better understand the
energy budget of a curing concrete bridge and 2) to
provide atmospheric boundary conditions to a model
of curing concrete.
New measurements included direct sensible and latent

This report presents the findings and recommendations for the following NJDOT?s technology transfer
projects:
Energy Absorbing Fender Systems
Existing bridge fender protective systems technology, used by other states and countries are grouped into six
main categories: 1) Pile supported; 2) Retractable; 3) Rubber; 4) Gravity; 5) Hydraulic/pneumatic; and 6)
Floating systems. A protection system composed of hardcore composite pile dolphins, composite tubular

This three-part research project examined three different sets of technologies ? energy-absorbing fender systems, pre-cast or prefabricated bridge deck systems, report presents the findings and 'smart bridges' ? and provided recommendations for how New Jersey DOT should proceed with implementing them.

Durability of concrete bridge decks to mechanical and environmental effects is examined for the
purpose of evaluation of effects of blacktop resurfacing of bridge decks. Aggressive environmental
actions on reinforced concrete are described, classified and equivalent environmental loads
presented. To explain effects of aggressive environmental loads, concrete transport properties
dependent on: concrete structure, external effects, mechanisms in concrete, and chemical reactions

Concrete delamination (spalling) in bridge decks is a serious problem. Damage in reinforced concrete structures is caused by many factors, such as alkali-aggregate reaction, faulty design and construction, reinforcement corrosion, corrosive action of chlorides, geotechnical problems, or in general by mechanical, chemical, physical, biological and environmental loads. The project examined the durability of concrete bridge decks to mechanical and environmental effects, for the purpose of evaluating the effects of blacktop resurfacing of bridge decks.
