Culvert Rehabilitation using 3D Printed Diffusers Project 2.11

Project C20.2020: Advanced Sensing Technologies for Practical UAV-Based Condition Assessment

Advanced Sensing Technologies for Practical UAV-Based Condition Assessment Project C20.2020 Project Summary The problem we are trying to investigate is the synergistic application of unmanned aerial vehicles (UAVs) with active acoustic sensing (AAS) and synthetic aperture radar (SAR) for the underside inspection of bridge decks. The problem is important because that employing such UAV-AAS-SAR system […]

Project 4.11: Safety Assessment of New England Roadways during the COVID-19 Pandemic

Safety Assessment of New England Roadways during the COVID-19 Pandemic Project 4.11 Project Summary Safety assessment of roadway facilities is a critical task to maintain the system operational efficiency of transportation infrastructure. The comprehensive stay-at-home orders implemented in response to the COVID-19 pandemic have resulted in massive reductions in traffic volumes, especially on major highways. […]

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 4.10: Road Salt Impact Assessment (Safety Study)

Road Salt Impact Assessment (Safety Study) Project 4.10 Project Summary The proposed study supports a project sponsored by Maine DOT titled as “Road Salt Impact Assessment.” Winter weather and maintenance treatments have significant impact on highway safety and operations. Understanding the safety impact of these factors directly influence decisions on diminishing maintenance funds, and cost-benefit […]

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 […]

Project 2.02: Concrete Systems for a 100-Year Design Life

Concrete Systems for a 100-Year Design Life Project 2.2 Project Summary The overall objective is to develop a suite of highly durable concrete systems suitable for a range of transportation infrastructure applications, given the range of constituent availability (e.g. appropriate aggregates, supplementary cementitious materials), conventions for structural details, and typical New England exposure conditions ranging […]

Project 3.11: Assessment of Micropile-Supported Integral Abutment Bridges

Assessment of Micropile-Supported Integral Abutment Bridges PHASE 2: Flexural Strength and Durability of Micropile Threaded Connections Project 3.11 Project Summary Integral abutment bridges (IABs) are the preferred method of construction by Maine Department of Transportation (DOT) and other transportation agencies throughout the United States due to their durability and reduced upfront and life-cycle costs. Shallow […]

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 […]
