Project C11-2019: Development of a system-level distributed sensing technique for long- term monitoring of concrete and composite bridges

Development of a System-level Distributed Sensing Technique for Long-Term Monitoring of Concrete and Composite Bridges Project C11.2019 Project Summary The problem we are trying to solve is the long-term monitoring problem of bridges (e.g., concrete and composite bridges), using multiple modes of sensing technology including distributed fiber optic, video motion, conventional strain gauge, and electromagnetic […]

Project C07.2018: Alternative Cementitious Materials (ACMs) For Durable and Sustainable Transportation Infrastructures

Alternative Cementitious Materials (ACMs) For Durable and Sustainable Transportation Infrastructures Project C7.2018 Project Summary Concrete produced with Alternative Cementitious Materials (ACMs) often exhibits superior mechanical performances and lower carbon footprint compared to those produced with Ordinary Portland Cement (OPC). ACMs also allow utilizing high-volume of industrial by-products as the binding materials instead of OPC, thus […]

Project C03.2018: Condition Assessment of Corroded Prestressed Concrete Bridge Girders

Condition Assessment of Corroded Prestressed Concrete Bridge Girders Project C3.2018 Project Summary The problem we are trying to solve is the condition assessment of corroded prestressed concrete (PC) bridge girders in New England. The problem is important because that PC bridge girders are a critical component of highway bridges. Concrete spalling and prestressing strand corrosion […]

Project 2.07: High Performance Concrete with Post-Tensioning Shrinking Fibers

High Performance Concrete with Post-Tensioning Shrinking Fibers Project 2.7 Project Summary This research improves upon the technique of reinforcing concrete with dispersed fibers by having the fibers axially shrink after curing to produce a dispersed multi-axial post-tensioned state. Such reinforcing may increase the crack resistance and durability of the concrete. Preliminary benchtop testing with natural […]

Thermoplastic Composites by 3D Printing and Automated Manufacturing to Extend the Life of Transportation Facilities Project 2.4

Project 2.03: Measuring Adhesion Between Binders and Aggregates Using Particle Probe Scanning Force Microscopy at Low Temperatures

Measuring Adhesion Between Binders and Aggregates Using Particle Probe Scanning Force Microscopy at Low Temperatures Project 2.3 Project Summary Low temperature cracking is one primary distress of pavement materials in New England area. It is estimated that only half of the major US roads are in good condition, whereas thirteen percent are in poor condition. […]

Project 1.04: Electromagnetic Detection and Identification of Concrete Cracking in Highway Bridges

Electromagnetic Detection and Identification of Concrete Cracking in Highway Bridges Project 1.4 Project Summary The problem we are trying to solve is the structural assessment of aging concrete bridges (reinforced and pre-stressed) in New England, targeting at concrete cracking and degradation (e.g., carbonation, alkali-silica reaction). The problem is important because that the integrity of concrete […]

Project 3.05: Prevention of Stressed-Induced Failures of Pre-stressed Concrete Crossties of the Railroad Track Structure: Phase I

Prevention of Stressed-Induced Failures of Pre-stressed Concrete Cross-ties of the Railroad Track Structure: Phase I Project 3.5 Project Summary The problem we are trying to solve is to understand and mitigate premature failures of pre-stressed concrete cross-ties (PSCCs), which are an essential structural component of a railroad track structure. The objectives of the project are […]

Project 2.05: Development and Testing of High/Ultra-High Early Strength Concrete for Durable Bridge Components and Connections

Development and Testing of High/Ultra-High Early Strength Concrete for Durable Bridge Components and Connections Project 2.5 Project Summary The objective of the research project is to enhance the robustness of current high-early strength concrete mixtures and develop mixture design specification of a next generation of high-early strength concrete to enable durable, sustainable and economical efficient […]

Project 1.11: Energy Harvesting and Advanced Technologies for Enhanced Life

Energy Harvesting and Advanced Technologies for Enhanced Lifentelligent Compaction with Passive Wireless Sensors Project 1.11 Project Summary The objectives of this project are:• to develop a perpetual pavement system with embedded solar harvesting unit• to perform Infrastructure Assessments Through Solar Energy Harvesting• to perform a thermodynamic analysis of the pavement cooling system and the pavement […]
