Available in PDF, EPUB and Kindle. Book excerpt: This paper is based on a research study aimed at determining the relative effectiveness of three bridge deck protective systems (i.e., latex-modified concrete (LMC) overlay, low-slump dense concrete (LSDC) overlay, and cathodic protection (CP) in preventing or halting reinforcing steel corrosion and corrosion-induced deterioration in salt-contaminated concrete. The paper documents the results of testing five LMC, five LSDC, and two CP bridge decks. The test bridges had experienced severe corrosion-induced deterioration and/or severe salt contamination before protection. At the time of testing the average age of both the LMC and LSDC overlays was about seven years, and the average age of the CP installations (slotted system) was five years. Also, among the concrete overlaid decks, seven had been subjects of previous similar investigations. Thus, the study determined changes in the effectiveness of concrete overlay protective systems with time.
