Title: RESEARCH PAYS OFF--AVOIDING THE COSTS OF CLOSURES AND DETOURS DURING BRIDGE DECK REHABILITATION

Availability: Find a library where document is available Abstract: The conclusion of NCHRP Synthesis of Highway Practice 86: Effects of Traffic-Induced Vibrations on Bridge-Deck Repairs is that no convincing evidence exists to indicate that the performance of a concrete deck is degraded by traffic-induced vibrations during placement or curing. Accordingly, the practice (now used under certain circumstances by many highway agencies) of allowing traffic in adjacent lanes during bridge repairs can be continued and expanded without unnecessary concern for its effect on the long-term durability of the new concrete. The Minnesota Department of Transportation reported that more than $104,000 was saved in a typical deck-repair project by the elimination of temporary median crossovers on two sets of bridges over minor crossings on Interstate and divided highways. Engineers in the New York State Department of Transportation estimate that by adopting the practices supported by this research, the state will save approximately $3 million each year. Similar savings are projected by the Texas Department of Highways and Public Transportation. On the basis of present levels of deterioration, the Federal Highway Administration estimates that the cost of needed bridge deck repairs over the next decade might be more than $25 billion. Thus, as these research findings are used to avoid the cost of closures and detours on many of these deck-rehabilitation projects, enormous savings will be realized nationwide. (Author)
