PEACE BRIDGE REHABILITATION

The 62-year old International Peace Bridge between Buffalo, New York and Fort Erie, Ontario is being rehabilitated with styrene-butadiene latex modified concrete (LMC). As traffic volumes mount, LMC is being specified more often for bridge deck overlays, especially in snow-belt areas. The LMC provides a more durable wearing surface combined with a high level of protection from the penetration of chloride ions from deicing chemicals. Trouble-free life of 10 to 15 years is expected for the new bridge deck. Details of the mix, the surface preparation, and LMC placement are described. The method of delivery (described) of LMC to work sites on the bridge was dictated by considerations of traffic control and structural integrity. Based on the success of the first phase, the original project schedule is being reduced by one year.
