Research Topics Ideas (RTIs)
RTIs are developed into Research Needs Statements (RNS) and 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.  
THE 2014 POLL RATING PERIOD IS CLOSED.
PLEASE SEE BELOW FOR THE RESULTS.  
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:  Compiled Poll Results        

 

1Rapid demolition methods for ABC projects 

Comments:

-Fast demolition in high traffic region will speed up  construction

This has been submitted as a RNS in 2015, but under "Demolition Requirements for Bridge Construction Projects; Best Practices Guideline".   Ref. to RNS No. 5 in our National ABC Research Project Tracker

 
 
 

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

Comments:

-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.

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

Comments:

  -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

Comments:

-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

Comments:

-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.
