NCHRP Project 14-30 3 CHAPTER 1 Background, Project Objectives, and Research Approach 1.1 Introduction Of the approximately 614,000 bridges in the FHWA National Bridge Inventory, about 170,000 are steel bridges that rely on protection from corrosion damage by thin film coatings or paints. Those coatings have a finite lifespan in relation to the steel they protect.

NCHRP Project 14-30 4 • Qualify spot coatings for spot painting repairs over specific existing coatings on bridges, and • Assess their potential service lives for those applications. Provide guidance for state highway agency officials to deploy spot painting - Identify commonly employed structural painting methods that constitute: • Best practices for spot painting on bridges incorporating the selection process, proper materials handling, cleaning, soluble salt remediation, mechanical surface preparation, verification of ambient conditions, coatings application, and compliance with worker safety and environmental regulations, and • Best practices for cleaning/mechanical surface preparation to the SSPC-SP 3 standard.
