SPR 775

Titanium for Strengthening Existing Reinforced Concrete Bridges
 Project Coordinator:
 Matthew Mabey
 Research Agency:
 Oregon State University
 Principal Investigator:
 Chris Higgins
 Start Date at ODOT:
 July 1, 2014
 Completion Date for ODOT:
 September 30, 2016
 
 
Overview:
The characteristics of titanium reinforcement, particularly its ability to be bent, open up possible cost savings for a wide range of strengthening situations.  Three areas have been identified for further research to exploit the advantages of titanium reinforcement for strengthening:
 
• Develop a splicing method that allows supplemental reinforcing bars to be deployed along the full length of girders including through the intermediate diaphragms that protrude from most beams.
• Develop an unbonded strengthening detail that eliminates the need to cut grooves into the concrete surface, thereby reducing labor costs, epoxy material costs, and construction time.
• Develop methods to apply exterior titanium bars to strengthen girders with inadequate transverse reinforcement.

 Quantifying Noise Impacts from ODOT Aggregate Source Operations
 Project Coordinator:
 Kira Glover-Cutter
 Research Agency:
 SLR International Corporation
 Principal Investigator:
 Jessica Stark
 Start Date at ODOT:
August 21, 2015
 Completion Date for ODOT:
 June 30, 2016
 
Overview:
The sage grouse as “endangered” by US Fish and Wildlife has the potential for significant impact to ODOT aggregate source operations.  The data collected in this research will assist in developing maps and other information and be used by ODOT environmental staff to work with ODFW to establish the area and degree of impact that ODOT aggregate production has on sage grouse.

SPR 777

Chip Seal Design and Specifications
 Project Coordinator:
 Jon Lazarus
 Research Agency:
 Iowa State University
 Principal Investigator:
 Douglas Gransberg/Chris Williams
 Start Date at ODOT:
 July 18, 2014
 Completion Date for ODOT:
 July 31, 2016
 
 
Overview:
 
The RFP defines the problem as a need to “revisit” ODOT’s chip seal design methodology and specifications using common chip seal design methodologies found elsewhere in the US and internationally as a benchmark to identify potential approaches to improve the ODOT chip seal program. ODOT requires a rational chip seal design methodology based on quantitative measurements that can be successfully replicated by contractors in the field and which does not demand the current amount of professional judgment to be successful.

SPR 779

 Risk Factors for Pedestrian and Bicycle Crashes
 Project Coordinator:
 Mark Joerger
 Research Agency:
 Portland State University/Oregon State University
 Principal Investigator:
 Chris Monsere/Haizhong Wang
 Start Date at ODOT:
 November 10, 2014
 Completion Date for ODOT:
 August 31, 2016
 
Overview:
Oregon has identified pedestrian and bicycle crashes as a primary focus area for investing infrastructure funding and has marked approximately $4 million in the All Roads Safety Program to help address this key need. Preliminary work towards this problem, ODOT TRS hired a consultant in Spring 2013 to prepare a plan and objectives to match effective safety systemic infrastructure countermeasures with potential high risk locations for improvements.

SPR 780

Strategies to Increase the Service Life of Existing Bridge Decks
 Project Coordinator:
 Matthew Mabey
 Research Agency:
 Oregon State University
 Principal Investigator:
 Burkan Isgar
 Start Date at ODOT:
 July 1, 2014
 Completion Date for ODOT:
 September 30, 2016
 
 
 
Overview:
 
This research is to provide ODOT with a protocol to select bridges for its ongoing bridge deck treatment operations using quantitative tools that are practical and quick. The quantitative tools will be in the form of concrete SR measurements, time-to damage predictions, and when necessary, strategically-selected chloride depth profiles.
 
It is anticipated that the Bridge Design and Drafting Manual will be revised to detail acceptable corrosion test methods for concrete structures and identify corrosion mitigation actions for different levels of chloride exposure.
