Investigation and Assessment of Effective Patching Materials for Concrete Bridge Decks

项目名称：	Investigation and Assessment of Effective Patching Materials for Concrete Bridge Decks
摘要：	Patching of deteriorated portions of concrete bridge decks is an important repair activity that has to be conducted in a timely manner to maintain the serviceability and extend the longevity of these vital links in our transportation infrastructure. Currently, the South Carolina Department of Transportation (SCOOT) specifies the use of ready-mix concrete (plant-produced) for bridge-deck patching. Alternative rapid set patching materials that are amenable to on-site batching and mixing with excellent bond characteristics and accelerated cure rates are desirable. The objectives of the research are to: (1) develop of a curated set of alternate repair materials; (2) develop a process of rapid investigation techniques through non-destructive testing to identify the cause and extent of deterioration in the bridge deck; and (3) develop guidelines, based on the above, to appropriately select suitable repair methods and materials.
