Field Evaluations Of Waterproof Membrane Systems For Bridge Decks 1972 1974 PDF Download

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.
