A 1/2 to 3/4-in.-thick (12.7 to 19.1-mm) hot-mixed membrane has been evaluated as a protective interlayer on bridge decks in seven states since 1966. Permeability, bonding, and stability under heavy traffic have been satisfactory and equivalent to other effective membrane systems at all locations. Requirements for mixing and placing with standard paving equipment are described. Compared with other membrane systems, the primary advantages of the hot-mixed membrane appear to be low cost, minimal deck preparation, use of standard paving materials and equipment, and ability to withstand heavy traffic for extended periods before there is a need for a wearing course. For one installation on a truck viaduct in Illinois in 1972, stone chips were pressed into the hot-mixed membrane mat to provide a textured surface in place of a wearing course. The hot-mixed membrane has been approved for use by the Illinois Department of Transportation. It is currently being used for bridge deck protection on a number of Inter-state highways. /Author/
