This bridge comprises five-lane double deck carriageways carrying more than 180000 vehicles per day. The concrete deck was last surfaced in 1963 with a spray coat application of Shell's Guardkote 140 gritted with fine aggregate. Tests are described which were undertaken to determine the best type of material for resurfacing the bridge deck. These consisted of 16 trial sections laid in 1971 in the right-hand lane known as the 'truck lane' heading west to San Francisco, and which included epoxy asphalt, several epoxy-type chip seals, polyester chip seals and two polyurethane chip seals. Normal asphalt and portland cement concrete were not considered because the thickness required for these materials would have resulted in excessive weight. The material eventually chosen for the project in 1976 was concresive epoxy asphalt, and the work was carried out at night during September and October of that year. Information is presented on the preparation of the deck to receive the new surfacing, traffic control, quality control, the materials used and application techniques. /TRRL/
