Structural steel coatings have long proven their cost effectiveness in preventing corrosion of our nation's steel bridge infrastructure. As technology develops in both structural steel (high performance steel) and coatings systems, their superior performance must be better understood.

In the early 1990s, the New England states formed an ad hoc committee dubbed NEPCOAT (North Eastern Protective Coatings Committee). NEPCOAT was instrumental in establishing regional and national standards for the bridge coatings industry. Through the AASHTO Subcommittee on Materials, standards were adopted for materials testing of bridge coatings on bare steel.

For purposes of this NTPEP evaluation AASHTO has contracted a private testing laboratory for all physical testing.

AASHTO lead states and NTPEP Headquarters communicates with the private testing laboratory regarding their services for the NTPEP program. Manufacturers are allowed to be present during actual application of their coatings on control panels at the private laboratory. After that event, for purposes of their NTPEP evaluation, communication is handled through NTPEP Headquarters.

FHWA's Office of Research and Technology has been very supportive of this AASHTO/NTPEP effort. Through the Bridge Coatings Technology Research program, federal funding has been provided for round robin testing. Also, monies are dedicated for correlation between lab testing and field exposure testing through NTPEP samples. This NTPEP Allied Research activity is ancillary to ongoing NTPEP evaluatons.

The NTPEP Project Panel responsible for authoring the Project Work Plan convenes yearly at the NTPEP National (Annual) Meeting. During this working meeting, the Project Work Plan is discussed; changes made, and shortly thereafter balloted for adoption. Improvements are immediately implemented in the next available testing cycle. When compared to other standards development exercises, the NTPEP process is agile, effective and efficient.
