Duplex Coatings on Kentucky Transportation Cabinet Bridges

by Bobby Meade, Greenman-Pedersen Inc.; and Sudhir Palle and Theodore Hopwood II, University Of Kentucky

Bridges have been historically designed for a theoretical 50-year service life but in many cases remain in service in excess of 75 years. This article discusses one tool that bridge designers can employ to extend bridge coating service life — the use of hot-dip galvanizing (HDG) and duplex coatings.

Evaluation of Surface Preparation Methods to Remediate Chlorides on Bridges

by Bobby Meade, Greenman-Pedersen, Inc.; Michael Baase, Kentucky Transportation Cabinet; and Theodore Hopwood Ii and Sudhir Palle, University Of Kentucky

The cost of maintaining a protective coating during the service life of a bridge can approach the cost of the original construction. The authors describe a KYTC-funded research project that assessed steel panels prepared by application of 32 different cleaning methods for quantity and deposition of retained chlorides.

Application of Two-Component Epoxy Intumescent Coatings for Passive Fire Protection

by Eric P. Rennerfeldt, Graco, Inc.

There is a growing demand to use plural-component proportioning equipment to spray 100-percent-solids coatings, which are usually high in viscosity and composed of materials that make them compressible during application. This article explains the more technical aspects of plural-component proportioning, discussing the different technologies and how each handles 100-percent-solids spray coatings.
