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1.13 Project Summary Most of the New England railway bridges were designed and built more than a century ago with outdated design codes and materials.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 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 1.16: Wireless Joint Monitoring System (w-JMS) for Safety of Highway Bridges

Wireless Joint Monitoring System (w-JMS) for Safety of Highway Bridges Project 1.16 Project Summary Infrastructure in the United States is currently confronting critical demand and supply challenges. A significant number of existing highway bridges have reached the end of their service life, while the load on these structures has significantly increased due to rising traffic […]

Project 2.15: Incorporation of Pollinator Plantings to Enhance Ecosystem Functions and Durability of Transportation Right-of-Way Infrastructure

Incorporation of Pollinator Plantings to Enhance Ecosystem Functions and Durability of Transportation Right-of-Way Infrastructure Project 2.15 Project Summary Highway right-of-ways (ROWs) provide numerous ecosystem services beyond erosion control. Incorporation of native grasses and flowering plants into ROW plantings can further increase the services by providing habitat for endangered native pollinators while improving aesthetics, erosion control, […]

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 2.18: Recycling Large-Scale 3 D-Printed Polymer Composite Precast Concrete Forms

Recycling Large-Scale 3 D-Printed Polymer Composite Precast Concrete Forms Project 2.18 Project Summary Large-scale thermoplastic composite extrusion-based 3D printing has been used in research labs and is moving into industry. One significant use of large-scale 3D printing has been to make forms for manufacturing precast concrete parts. Once the forms have been used for casting […]

Project 1.14: Exploring the Safety Impact of Rumble Strips on Prevention of Lane Departure Crashes in Maine

Exploring the Safety Impact of Rumble Strips on Prevention ofLane Departure Crashes in Maine Project 1.14 Project Summary Enhancing safety of roadway segments is a critical step towards maintaining durable transportation infrastructures. Due to significant costs associated with construction of roadway segments, redesigning or rebuilding a roadway segment is not always a viable solution for […]
