Corrosion Free Bridge Decks (CFBD) | Print |


"Corrosion-induced damage of bridge decks results in excessive cracking and spalling in the concrete that leads to a loss of serviceability, ultimately affecting the structural safety of the bridge. The rehabilitation costs of deteriorated decks account for about one-third to one-half of total bridge maintenance costs in North America.” Construction Innovation, December 2004 Institute for Research in Construction.

CFBD advantages:

Reduces thickness of deck slabs hence reducing dead load of structure
Produces additional load capacity
Extends life of structure
Costs less to construct
Costs less to maintain
