Book Description
This report covers the application of four membrane systems on eight new bridge decks in 1977. Information includes data on the membrane systems, laboratory test results, condition of the bridge decks, observations made during the membrane applications, cost information, preliminary field test results and discussions on the applications. The report also includes summaries of field and laboratory observations on membrane systems applied in the years 1971 through 1976. Two of the three experimental membrane systems discussed in this report were applied in an attempt to reduce or eliminate the formation of initial and post-construction blisters. Both products were basically successful in reducing the amount of air entrapped beneath the materials during placement and in doing so probably reduced the occurrence of blistering during the pavement application. The reduction in entrapped air was accomplished by the presence of self sealing vent holes in the Royston No. 10PV membrane and by the increased adhesion developed by the Royston No. 15 system. The Tri-Ply system shows merit although a more definite means of obtaining adhesion between membrane and substrate would be desired on any future application. Four of five control decks treated with the standard Royston Membrane No. 10 were free of significant concentrations of entrapped air and remained free of blisters or cracks during the pavement applications. All three types of Royston Membrane will be inspected periodically for any sign of post construction blistering.

Book Description
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.

Book Description
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.

Book Description
An electrically conductive asphalt concrete was made by substituting coke breeze for the natural aggregate. Paving a bridge deck with the electrically conductive asphalt concrete indicated that cathodic protection could be applied to the reinforcing steel. The cathodic protection was measured to be effective when the corrosion of steel strips embedded in concrete containing 10 percent calcium chloride by weight of the cement was stopped.
