Prolonging bridge life through innovative approach to de-icing operations

This paper provides a brief review of the adverse effects of rock salt on reinforced concrete bridge structures, the roadside natural environment, the life cycle of highway structures, and the attendant financial cost implications. It addresses the issue of whether the adoption of an alternative method of winter operations for highway bridges, combined with the use of alternate de-icing salts, could constitute a viable, cost-effective and sustainable solution. The University of Surrey and Anglia Polytechnic University in the UK are currently evaluating the effects of two biodegradable de-icers; Calcium Magnesium Acetate (CMA) and Sodium Acetate (NAAC), on the behaviour of reinforced concrete highway bridge structures. Initial results obtained from this study are presented and discussed with respect to the optimum condition for their application on highway structures. Conclusions are drawn on the basis of the practical implication for the life cycle of corrosion-prone highway structures and the natural environment. The need for further investigation is identified.
