If you know of a completed or ongoing project that should be included in the tracking spreadsheet, have a new research idea, or would like to sponsor a project - please send your information to the following email link: ABC Research Topic     
   Research Topics Ideas (RTI)
Research Topic Ideas (RTI)  that are developed into Research Needs Statements (RNS) are submitted to TRB, AASHTO, FHWA, State DOTs, and other entities for further consideration. 
To indicate the level of interest for a particular RTI, please rate them as noted below. Rating an RTI is open to all - one vote per person. 
Volunteers are needed to develop RTIs into RNS.  If there is a particular RTI of interest to you, please submit your contact information when prompted under the corresponding "Rate this RTI" link.        
Compiled results from the March 20, 2014 poll can be found at the following link:  3/20/14 Compiled Poll Results        


1Rapid demolition methods for ABC projects 


-Fast demolition in high traffic region will speed up  construction


Chart 1


Chart 2


2. Workforce fatigue on ABC projects using PBES: safety and project quality


-Can this be combined with No. 7?

-I think this is an imporatant aspect of ABC that needs to be given consideration in the planning and procurement of projects - particularly on a programmatic basis.

-Should this be expanded to include night-time work or round the clock work.  I guess that this is probably already included in the idea.

3. Contractor's means and methods on ABC projects using PBES: a side by side comparison - (Synthesis)

-This could help provide insight to actual cost and time elements of PBES

-This subject can help designers develop specifications that are consistent with the current installation practice of PBES on bridge projects.

-Maybe make into more of a synthesis topic?

4. Material considerations for ABC projects

-Seems like this is something that really holds back some use of ABC.

-Closure and joint grout type material I presume.

5. Construction Engineering Inspection for ABC projects using prefabricated bridge elements and systems


-Consider combining w/ No. 9?

6. Current state of practice of ABC projects using Self Propelled Modular Transporters: domestic and international update

-Could include lessons learned.

7. Quantifying safety improvements for ABC projects using PBES


  -Combine with No.2?

8. Modern survey and site scanning technologies to facilitate prefabricated bridge elements and systems for ABC Rate this RTI

9. Design, fabrication, and field fit up considerations for prefabricated bridge elements and systems


-Ref. No. 5, should this be combined?

-Consider renaming to: Designing for fabrication and field fit up considerations ..." and keeping it seperate from No. 5

-How is it packaged and assembly is very important, and effect the whole project.

-NCHRP 12-98 may cover this?

-Do we mean 'tolerances'

10. Overall project delivery impacts of ABC projects - planning through completion: cost and schedule comparisons


-This may be a synthesis.  Once complete, it may lead to more research work.

11. In-service bridge inspections for ABC projects built using PBES technologies

-Let's collect information as early and as much as possible to gage the quality of using PBES and "debug" and improve ABC. Inspection data is so valuable.

-Concerned with life cycle and inspectability.
