On-Going Projects

1st-Cycle Projects (2016-grant)

  • Accelerated Repair and Replacement Of Expansion Joints:  The objectives of this research are to conduct a literature review on replacement and elimination of bridge deck expansion joints; to develop methods for accelerated bridge expansion joint replacement and elimination; and to promote ABC for bridge deck expansion joint repair.
  • Bidding of Accelerated Bridge Construction Projects: Case Studies and Consensus Building:  This research project will consist of a thorough exploration of current bidding methods for ABC projects via surveys, case studies, content analysis, interviews, documentation and observations.
  • Contracting Methods for Accelerated Bridge Construction Projects: Case Studies and Consensus Building:  This research project will consist of a thorough exploration of current contracting methods for ABC projects via surveys, case studies, content analysis, interviews, documentation and observations.

3rd-Cycle Projects (2013-grant)

  • Inspection and QA/QC for ABC Projects:  The objective of this research is to explore available nondestructive testing technology to determine applicability for the inspection and quality control of accelerated bridge construction components.
  • Integral Abutment Details for ABC Projects, Phase II:  The proposed research aims to develop ABC compatible integral abutment connections to marry the two technologies together and continue to advance the quality, performance, economics and constructability of bridges to meet the demands of today’s growing infrastructure.
  • Development of Guidelines to Establish Effective and Efficient Timelines and Incentives for ABC:  The main objective of the proposed project is two folds: 1) Provide guidelines to evaluate the direct and indirect costs (traffic delays and opportunity losses) under following conditions: conventional construction, only ABC techniques, only incentivizing strategies, and combination of ABC and incentivizing strategies; and 2) Develop a decision-making framework to compare the total costs and durations of each of the candidate techniques to optimize for the lowest cost and construction duration techniques accordingly.
