Background

Maintenance and repair of a concrete bridge deck is costly and disruptive process for a department of transportation. With limited funding available to keep all the bridge decks in a state of good condition, analysis tools are needed to better understand the life cycle of a bridge deck. It is essential to understand what parameters drive deterioration of untreated concrete bridge deck and superstructure components. Department of transportation’s vision is to increase the service life of highway bridge decks. Currently, the standard service life of a highway bridge deck is considered to be approximately 30 years, while the standard design life for a highway bridge is 75 years. Long term bridge performance is currently not well understood quantitatively. In practice, engineers are forced to rely heavily on expert opinion and generalization; with the move towards asset management strategies to reduce life-cycle cost, they are no longer sufficient. As a part of the MAP-21 (Moving Ahead for Progress in the 21st Century Act) requirements for life cycle planning, it is required to establish “a process to estimate the cost of managing an asset class, or asset sub-group, over its whole life with consideration for minimizing cost while preserving or improving the condition.” This requires us to establish a deterioration models for asset conditions that reflect the natural deterioration rate of bridges. The study will record the deterioration parameters during the accelerated testing without inclusion of interventions or treatments. Bridge deterioration is entirely studied using direct observation, NDE, or standard durability tests that operates on small scale. Unfortunately, none of these approaches can generate the type of objective and reliable information on long term bridge performance needed to implement modern asset management system. As a result of these shortcomings, NJDOT has decided to lead a pool fund study of accelerated testing of a full scale bridge deck that can simulates how various deterioration mechanism interact to produce the long term performance in practice.

Objectives

This proposed research will collect and integrate state specific data set to address questions and practices specific to members of the project. The research team will identify parameters and methods needed to assess life cycle & forecast the performance of a - concrete bridge deck; coating system for steel girders; elastomeric bearing; and various type joints. These parameters may affect the design, detailing, construction, traffic load, use of deicers, and other maintenance practices. ? Determination of base deterioration curves and difference in long term performance of the following systems and bridge components during the accelerated testing: • Untreated reinforced concrete decks with various type of reinforcement • New Jersey specific three coat painting system for steel girder • Elastomeric bearing and various types of joints • Influence of axle weights on the deterioration and service life of untreated reinforced concrete decks.

Scope of Work

1.1 – Literature Survey • Provide an important comparative benchmark for the accelerated testing program 1.2 – Development of Detailed Experimental Plan • Detailed plan to satisfy the objectives • Full scale bridge superstructure design and justification for all design decisions 1.3 – Specimen Construction and Instrumentation • Detailed documentation of construction process as well as testing of materials 1.4 – Test Execution and Data Collection • Perform accelerated testing and ongoing interpretation of all data 1.5 – Data Interpretation • Detailed analysis of all data collected to satisfy goals/activities 1.6 – Reporting • Preparation of final report which include testing data, conclusion and state specific recommendation

Comments

Each State total minimum contribution of $50,000. ($25,000/year)

Subjects: Bridges, Other Structures, and Hydraulics and Hydrology Maintenance
