Title

NJDOT Corrosion Study on Steel Structural Members

Abstract

Given the large portion of steel infrastructure in New Jersey, and the need to maximize the service life of new structures, while extending the life of existing structures, it is critical to understand the rate and nature of steel corrosion in the state. The proposed research will seek to provide that understanding and the tools to estimate the corrosion that may be expected for a given member considering its exposure parameters. As such the objectives of this research are as follows:

1. Determine the state of knowledge on steel corrosion and the state of practice for corrosion protection.
2. Ascertain the types of data (condition, maintenance, exposure, etc.) that already exist and may be leveraged for analysis.
3. Determine the parameters influential to steel corrosion, and the effect of those parameters on remaining service life.
4. Develop a predictive model that can estimate the expected rate of corrosion or the remaining service life for a given structural member.
