Abstract

Highways and railways move the major volume of freight tonnage in the nation. The impact to the freight hauling industry created by disruption due to construction is tremendous. Bridges are the most sensitive components for construction in both railroad and highway systems. While highways and rail lines can be repaired relatively quickly, bridges require special planning, engineering, materials procurement, and longer construction time. This study proposes to develop a bridge replacement/ construction decision-making framework using possible Analytical Hierarchy Process (AHP), and exploit innovative methods for accelerated construction of highway and railway bridges that explicitly address materials, design and prefabrication of bridge elements, and construction machinery for assembling the structural components. The findings will be added to a graduate-level course in transportation asset management at the University of Illinois at Chicago and Illinois Institute of Technology.

Objectives

To advance technology, knowledge, and expertise in the planning, design, construction, and operation of sustainable freight transportation infrastructure through education, research, outreach, and training.

The research will focus on two technical aspects of developing innovative methods for accelerated replacement or construction of highway and railway bridges: 1) a bridge replacement/construction decision-making framework to determine the required level of rapidity in response, appropriate design/construction alternatives, and cost/benefit characteristics of selected processes; and 2) an innovative system for accelerated bridge design/construction.

Tasks

  1. Synthesis of current state-of-practices of accelerated bridge replacement/ construction methods,
  2. A bridge replacement/construction decision-making framework, and
  3. An innovative system for accelerated bridge replacement/construction.
