Duplex Coating on KYTC Bridges

Duplex Coating on KYTC Bridges
Available for download

The 2014 US bridge inventory lists over 610,000 highway bridges. Industry experts believe that the cost of maintaining those bridges for repairs due to corrosion is at least $30 billion annually. Bridge owners do not have the resources to maintain bridges in good condition. New bridges are being constructed, at the rate of approximately 3,000 nationally each year. Those new bridges must not pose additional maintenance burdens on the already inadequate bridge maintenance budgets.

Bridge owners do not have the resources to maintain bridges in good condition. New bridges are being constructed, at the rate of approximately 3,000 nationally each year. Those new bridges must not pose additional maintenance burdens on the already inadequate bridge maintenance budgets. The Federal Highway Administration (FHA) has long sought a 100-year bridge design. Bridges have been historically designed for a theoretical 50-year service life but in most cases remain in service for 75 plus years. To seek design service lives of 100 years, implies that the foreseeable service lives will actually exceed 100 years. One tool that bridge designers can employee in seeking this goal is the use of hot dip galvanizing (HDG) and duplex coatings for bridges where appropriate.

Putting the Pieces Together: Integrating Steel Repairs with Bridge Painting Projects

Many bridge painting projects include steel repairs as part of the contract. Painting and steel repairs are performed by separate trades and often separate contractors. Even designers may see them as separate activities. However, steel repairs and coatings must work together and be installed as a system to perform as intended. This paper is a discussion about the process of installing steel repairs and painting a bridge at the same time.

Key Points Specifically For Transmission Pipeline Coating

Product Number: 51322-17760-SG
Author: Ron Raphoon
Publication Date: 2022
$20.00

The bulk of a pipeline coating is shop applied and those processes are typically automated. Because
the automation of pipeline coating has so many controls, there is little need to address the inspection on the body of the mainline coatings. As such, this paper will address inspection of pipeline specific coating types and their unique considerations in a field environment. It will address concerns around tie-ing into other coating types and compatibility.
