Investigation of Bridge Deck Protection Systems
The study evaluated the effectiveness of various protection systems used for rehabilitation of existing salt contaminated bridge decks. Protection systems placed and tested included a Stratfull design type cathodic protection; low slump and latex modified concrete wearing surfaces; sheet types Protecto Wrap M-400A and Heavy Duty Bituthene; and liquid types Gacoflex UWM-2811, and Superseal 4000LT membrane systems. All protective systems were overlaid with asphaltic concrete except for low slump and latex modified concrete. Each of the protective systems provided a relatively maintenance free overlay for a five to eight year period. Rutting and shoving of the asphaltic concrete was minor but was the predominant problem with membranes and cathodic protection systems. Low slump and latex modified concrete overlays provided the smoothest riding surfaces. Membrane systems protected the deck concrete from ingress of chloride ions.
