Available in PDF, EPUB and Kindle. Book excerpt: Performance of protective coatings for bridge decks is evaluated. Applications to bridges on the New York State highway system from 1961 through 1967 included 1) surface overlays, 2) membranes between the structural slab and bituminous wearing course, and 3) surface sealants. Overlays and membranes consisted of epoxies, polyesters, polyurethanes, latexes, neoprenes, silicone rubbers, and asphalt cutbacks. Surface sealants included silicones, distillate oils, and linseed oil. None of the surface overlays lasted more than 2 to 3 yr. However, a flexible polyester resin with fiber glass has provided satisfactory service for 1-1/2 yr and will remain under observation. Leakage of box-girder bridges with a membrane was primarily due to shear-key construction (since modified), while the same materials applied to composite bridges were associated with leakage that could not be explained. A more comprehensive survey of membranes is planned. Silicone and distillate oil sealants on non-air-entrained concrete did not improve long-term durability. Air-entrained concrete, both with and without linseed oil treatment, showed no evidence of deterioration after 4 yr of exposure.

Available in PDF, EPUB and Kindle. Book excerpt: Intrusion of moisture and deicing chemicals into reinforced concrete bridge decks results in premature deterioration of the concrete and corrosion of the reinforcing steel. Vermont's search for an effective waterproofing system which would seal bridge decks and thus prevent intrusion of the moisture and chlorides has resulted in the application and evaluation of 29 different membrane systems since 1971. A number of the protective membranes have been in service for sufficient time to draw conclusions on their effectiveness. The results of followup evaluations show that several systems have provided complete protection to the bridge decks while a number of other materials have prevented chloride intrusion except in areas where deicing chemicals are often trapped due to the ponding effect of curb lines and expansion dams. Such results suggest that the simple and inexpensive materials could be specified for sealing the major portion of a deck surface if a compatible and impervious membrane material is placed over poorly drained areas. Difficulties encountered with the application of sophisticated and expensive membrane systems have resulted in a theory that the search for the most effective waterproofing system should concentrate on uncomplicated and less costly materials which could be applied without difficulty.

Available in PDF, EPUB and Kindle. Book excerpt: Measures to reduce or eliminate bridge deck deterioration by the use of various protective systems have been the subject of a series of reports begun in 1976. This report presents current observations of latex modified deck topping concrete protective systems. Latex modified concrete topping has not provided long-term protection for the ten structures under evaluation in Colorado, Cost comparison are made between repair with latex modified concrete and deck replacement. Over a 40-year period, replacement costs are slightly less than rehabilitation costs. Greater control of the curing of deck topping material may reduce shrinkage cracking. Nightime paving, cooler calmer weather and higher humidity would increase the probability of success on latex modified concrete to rehabilitation projects. Asphalt membrane and asphalt overlay are also suggested to increase the probability of success. Implementation: Latex modified concrete is not recommended as a rehabilitation option in Colorado at this time. Further evaluation of two structures using latex modified concrete under nigh paving and tight control of curing methods is currently underway on I-25 North of Longmont.

Available in PDF, EPUB and Kindle. Book excerpt: From 1976-1981 the Minnesota Department of Transportation (Mn/DOT) conducted a research study to evaluate several new types of bridge deck protective systems in an effort to reduce the extent of reinforcing steel corrosion. These systems included membranes with bituminous overlays, modified concrete overlays, and coated rebars. When the study concluded, it was felt that a long term study was needed to provide a better indication of service life. Two decks from each system type which appeared promising were selected for extended testing. This extended study continued the evaluation program through 1990
