January-March 2015 Quarterly Progress Report – Synthesis: Rapid Bridge Rehabilitation

Task 1 –  collecting information 

To complete Task 1 information related to the project were collected.  This included using search engines available online and at the Iowa State University Parks Library.  These pieces of information were documented by creating a working list of identified resources, topical information contained within each one, authorship, date, etc.  The identified resources were then categorized by the topical information contained within each one.  Following the collection of available information, the information was synthesized as part of Task 2.

Task – 2 Synthesizing the Information

To accomplish Task 2 each piece of literature was first read from beginning to end to gain an understanding of the information contained within.  Then each piece of literature was reviewed once again such that the important pieces of information could be extracted.  These important points were logged and added to a complete listing of findings.  Then, each piece of literature was summarized completely making sure to track the important points while also ensuring that the broad scope was well represented. A draft of the project front matter is included below.  This draft front matter gives a good representation of the types of information that has been identified and synthesized.

In short, the results of the synthesis revealed that there has been very little research/development of technologies/techniques that are specifically targeted towards rapid bridge rehabilitation.  This is likely an area where additional research efforts could be made.  Fortunately, it does appear that there are numerous ABC technologies used for new construction that could be used in rapid repair and/or rehabilitation.  As is probably not too surprising, the majority of information that could be adapted from new construction relates to decks.  Further, the information related to decks ranges from rapid protection all the way to rapid full replacement.

Information on rehabilitation of superstructures is available but very limited.  And, information pertaining to substructures is even more limited.  It is felt that the greatest opportunity for developmental work would be in the area of developing rapid means of widening existing superstructures and substructures.  These technologies would be more about how to facilitate widening/etc. without disrupting traffic on the existing portion of the structure.

Task 3 – Preparing a written report 

Results of study are being documented. Compilation of these reports will form the final report.
