This synthesis will be of interest to research, specifications, materials, design, and construction engineers; contract and specification administrators; agency project managers and staff; and concrete bridge deck construction contractors. This synthesis describes the state of the practice with respect to the development and present status of waterproofing membranes for concrete bridge decks. This report of the Transportation Research Board describes the use of waterproofing systems applied to new bridge decks and the rehabilitation of deteriorated concrete bridge decks. In addition, this synthesis describes current practice with regard to methods for assessing the effectiveness of membranes, criteria for use, installation practices, and factors that affect the performance of waterproofing systems in new construction and rehabilitation. Suggestions for future research are also included.

This report documents and presents the results of a comprehensive assessment of the protective capabilities of all bridge deck waterproofing membranes known to be available when the project started (1970). An extensive program of laboratory testing supplemented by a limited program of field study led to the selection from an original group of 147 systems, five that appeared most promising for more intensive field evaluation. Materials and construction specifications were prepared for the five systems, in addition to an experimental plan for the field evaluation. The new work is being under taken as a second phase of the study.

Waterproof membrane systems are being studied by many agencies from the standpoint of their effectiveness in protecting the reinforcing steel in concrete bridge decks against corrosion. Trial applications and evaluations of six such systems, including both preformed sheet and liquid membranes, were made in Virginia during the period from 1972 through 1974. These field evaluations included observations of the installation procedures and assessments of the subsequent waterproofing effectiveness of the systems through electrical resistivity measurements. While none of the systems could be considered an unqualified success, four of the systems showed promise, with modification of the application techniques used in the study, of providing the desired degree of long-term protection. Specific details of the application techniques and performances of each of the membrane systems are presented as is an evaluation of the effectiveness of earlier epoxy resin sealcoats.

This study develops a methodology for field appraisal and evaluates the effectiveness of three selected waterproofing membrane installations presently in service in the State of Washington. Based on the information obtained, none of the test installations had completely sealed the passage of salt into the concrete decks. "Active" and "uncertain" corrosion potentials existed at the rehabilitated portions; however, a decrease in corrosion activity since the time of rehabilitation was noted. Concrete deterioration after rehabilitation has occurred mainly within the boundaries of the repair work and original conrete, and it is more evident in areas with a shallower rebar depth. It is recommended that future research include a greater number of bridge decks. In addition, service life performance data should be obtained through long-range monitoring of the installations.
