摘要

Three hundred bridge decks were surveyed for three years to determine the rate of progress of deterioration and effectiveness of asphaltic bituminous covers in preventing damage. Covers were changed on many bridges during the period, leaving only 197 with constant cover. Most of the hot mixes had been on the bridges since their construction six years previously, whereas the other decks were bare in 1961. Although hot mixes and cold mats have similar thicknesses, they are different from each other and from the other categories in construction and behavior. (Author)
