Project 2.16: Enhancing the Durability of Bridge Decks by Incorporating Microencapsulated Phase Change Materials (PCMs) in Concrete

Enhancing the Durability of Bridge Decks by Incorporating Microencapsulated Phase Change Materials (PCMs) in Concrete Project 2.16 Project Summary In Rhode Island and other New England states, combined effects of freeze-thaw-induced damage and chloride ingress (from deicing salts) make it very challenging to maintain the quality of concrete on bridges and road surfaces. This project […]

Project 3.16: CT bridge girder sections with precast decks and FRP girder-deck shear

CT Bridge Girder Sections with Precast Decks and FRP Girder-Deck ShearConnectors Project 3.16 Project Summary UMaine recently developed and commercialized, in partnership with AIT Bridges, a novel, fiber‐reinforced polymer (FRP) composite bridge girder. This project focuses on the assessment of the fiber‐reinforced polymer tub girder (CT girder) with precast concrete decks and new, FRP girder‐deck […]

Project 1.15: Non-Contact Intelligent Inspection of Infrastructure

Non-Contact Intelligent Inspection of Infrastructure Project 1.15 Project Summary The objective of this research is to develop non-contact sensing mechanism for infrastructure monitoring as well as the associated machine-learning based technique for decision making. Currently available sensory systems for structural health monitoring are almost all based on transducers that are directly attached to or embedded […]

Project 1.13: Structural Integrity, Safety, and Durability of Critical Members and Connections of Old Railroad Bridges under Dynamic Service Loads and Conditions

Structural Integrity, Safety, and Durability of Critical Members and Connections of Old Railroad Bridges under Dynamic Service Loads and Conditions Project 1.13 Project Summary Most of the New England railway bridges were designed and built more than a century ago with outdated design codes and materials. The objective of this research project is to investigate […]

Project C17:2020: Durability of Modified Helical Piles Under Lateral and Torsional Loads: Embracing Efficient Foundation Alternatives to Support Lightweight Transportation Structures

Durability of Modified Helical Piles Under Lateral and Torsional Loads: Embracing Efficient Foundation Alternatives to Support Lightweight Transportation Structures Project C17.2020 Project Summary Modified helical (i.e. screw) piles are lightweight deep foundation elements that are screwed into the ground and efficiently generate geotechnical compressive and uplift resistance by mobilizing the shear strength of soil adjacent […]

Project 1.12: Improved UAV-Based Structural Inspection Techniques and Technologies for Northeast Bridges

Improved UAV-Based Structural Inspection Techniques and Technologies for Northeast Bridges Project 1.12 Project Summary Unmanned aerial vehicles (UAVs) or “drones” are revolutionizing some basic reconnaissance, including structural inspections. This project seeks to enhance and expand the range of applications for unmanned aerial vehicles (UAVs) to aid inspection of transportation structures. This project is primarily aimed […]

Damage Modeling, Monitoring, and Assessment of Bridge Scour and Water Borne Debris Effect for Enhanced Structural Life Project C19.2020 Project Summary The objective of this project is to evaluate bridge failure risk due to bridge scour and waterborne debris impacts to enable predictive management for enhanced structural life. The proposed multi-disciplinary project will establish a […]

Project 3.14: FRP-Concrete Hybrid Composite Girder Systems: Web Shear Strength and Design Guide Development

FRP-Concrete Hybrid Composite Girder Systems: Web Shear Strength and Design Guide Development Project 3.14 Project Summary UMaine recently developed and commercialized, in partnership with AIT Bridges, a novel, fiber-reinforced polymer (FRP) composite bridge girder. This project will assess the shear strength of foam-core webs of the girders using a combined experimental and analytical approach. Data […]

Project 3.10: Assessment and optimization of double CT bridge girder sections with longitudinal precast decks

Assessment and Optimization of Double Ct Bridge Girder Sections With Longitudinal Precast Decks Project 3.10 Project Summary This project focuses on the extension of novel, fiber-reinforced polymer tub girder (CT girder) sections to incorporate precast concrete deck panels. This will extend the application of this new bridge technology by modularizing construction, optimizing the use of […]
