Prior to 1970 many bridge decks in virginia were constructed with aggregates that polish when subjected to traffic. in the seventiesmany decks were constructed with insufficient macrotexture to provide a good bald tire skid number. to provide adequate macrotexture, atined texture has been applied to most decks constructed in the eighties. because of problems with achieving a uniform texture with tining, grooves were being sawcut on new decks constructed in the latter part of 1989. other techniques that have been used experimentally to increase the skid resistance of decks include shotblasting and sealing, application of a latex modified slag slurry and application of thin polymer overlays. the paper describes the techniques and compares them from the standpoint of skid number, the permeability to chloride ion of the top 2 in. of the deck, cost, and application requirements. this paper appears in transportation research record no. 1290, third bridge engineering conference, march 10-13, 1991, denver, colorado, volume 1.
