Peter J. Weykamp, P.E. NYSDOT Transportation Maintenance Division 50 Wolf Road, POD 51 Albany, NY 12232 (518) 457-8485 [email protected] Synopsis: Bridge maintenance involves performing long term treatments and repairs in a short period of time with minimal equipment under live traffic conditions. Traffic volumes and user delays discourage overnight or long term lane closures. Therefore, innovative and unique repair materials are necessary to get the lane back into service as quickly as possible. Fortunately, there is no shortage of product vendors soliciting the bridge maintenance community to try their new or improved products. Unfortunately, their claims often exceed actual performance. This presentation highlights some of the promising products tried by NYSDOT bridge maintenance forces. New materials suited to common bridge maintenance needs, such as expansion joint and deck repairs, will be presented. The advantages and limitations of each product will be discussed. A few non-material products, such as hardware and equipment, that have proven useful in bridge maintenance will also be presented. About the Presenter: Peter Weykamp received his B.S. from the University of Buffalo in 1983 and his M.P.A. from the State University of New York at Albany in 1988. He is currently the Bridge Maintenance Program Engineer for NYSDOT Transportation Maintenance Division. This work involves establishing bridge maintenance goals, network and project level programming for minor repairs and preventive maintenance for all state-owned highway structures. Pete works closely with Regional Bridge Maintenance Engineers to improve maintenance procedures, evaluate materials and methods, and identify program needs. Pete has over 21 years of experience in bridge design, research, construction, and maintenance on projects for the NYSDOT. SESSION 5.2 New Products in Bridge Maintenance
