Detection and Monitoring of Material Aging and Structural Deterioration using Electromagnetic and Mechanical Sensors with Virtual Reality and Machine Learning Modeling Project 3.19 Project Summary The problem we are trying to solve is the detection and monitoring of aging civil infrastructure components and systems in New England by using visual information and subsurface images in […]

Project 4.13: Development and Application of a Cost-Benefit Tool for Quantifying External Social Impacts of Small to Mid-Size Transportation Projects

Development and Application of a Cost-Benefit Tool for Quantifying External Social Impacts of Small to Mid-Size Transportation Projects Project 4.13 Project Summary This two-year project will focus on developing methods for quantifying the external social costs of transportation civil infrastructure projects, particularly small to mid-size projects that are common in New England states. Transportation projects […]

Project 3.21: GBeam Bridge Girder Pultrusion: Section Design and Optimization

GBeam Bridge Girder Pultrusion: Section Design and Optimization Project 3.21 Project Summary The GBeam girder system, recently developed by the University of Maine (Dagher et al. 2019; Davids et al. 2022a; Davids et al. 2022b), holds significant promise for widespread application in conventional, slab-on-girder bridges. Its successful initial implementation is driven by enhanced durability, low […]

Project 1.20: Monitoring Rail Bed Infrastructure Using Wireless Passive Sensing

Monitoring Rail Bed Infrastructure Using Wireless Passive Sensing Project 1.20 Project Summary Assessment and monitoring the performance and health of rail structures is an essential aspect of prioritizing the repair and replacement, as well as extending service life, of these transportation infrastructures. Intrusion of fines from the subgrade or surface leads to ballast fouling and […]

Project 3.17: Assessment of CT Girder Load Distribution and Web Buckling Through Field Load Testing and Finite-Element Analysis

Assessment of CT Girder Load Distribution and Web Buckling Through Field Load Testing and Finite-Element Analysis Project 3.17: Field Live Load Testing and Advanced Analysis of Concrete T-Beam Bridges to Extend Service Life Project Summary Recent and ongoing research has highlighted the need to better understand and quantify web shear capacity as well as the […]

Project 1.19: Assessing Presence and Impact of REOB (Recycled Engine Oil Bottoms) on Asphalt

Assessing Presence and Impact of REOB (Recycled Engine Oil Bottoms) on Asphalt Project 1.19 Project Summary Asphalt material producers sometimes incorporate Recycled Engine Oil Bottoms (REOB) into paving asphalt in order to alter its performance grade (PG). State Departments of Transportation express concern that REOB decreases pavement lifetime, even though it does not violate the […]
