ABSTRACT
It was decided for chloride levels above 1% with respect to cement mass, options 4 or 5 would be selected as option 3 becomes less effective at high chloride levels. Certain portions of bridges B1292, B1293 and B1294 fell in this category. This included the soffit edges and cross beams on bridges B1292 and B1293, and the canal column on bridge B1294. A life cycle cost analysis was performed to select between options 4 and 5. It was decided to apply ECE to selected portions of bridge B1292 and B1294 and to rebuild B1293.
