- 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.
- Material Design and Structural Configuration of Link Slabs for ABC Applications: The objective of this research is to develop details and recommendations to properly implement a link slab in joint-less bridges constructed with ABC techniques. This will be accomplished through a comprehensive set of experimental tests and numerical simulations.
- Investigation of Macro-Defect Free Concrete for ABC including Robotic Construction: The goal of this project will be to assess important characteristics and to develop conceptual uses for this new material with a specific focus on accelerated/robotic bridge construction.
- An Integrated Project to Enterprise-Level Decision Making Framework for Prioritization of Accelerated Bridge Construction: This project aims to develop a decision-making algorithm that brings together the project-level decision process that involves the choice of optimized construction techniques together with the enterprise-level process that implements regional prioritization schemes considering indirect costs (such as drivers’ delay, economic impact, opportunity losses, economic growth, and social investments) in addition to the direct costs associated with implementation of the ABC techniques.
