Project description

The increased use of deicing chemicals requires that some bridge decks be waterproofed to maintain their good condition. A variety of options are available, each of which has varying degrees of effectiveness, cost, and longevity. There are a range of waterproofing options including waterproofing membranes, polymer asphalts and laminates. Some of those can be maintained over the life of a bridge with periodic renewal of the wearing surface. Others can be replaced easily. Some membranes can be applied by state crews while others must be applied by external contractors. These options need to be investigated to create a toolkit of options for treating bridge decks.
