Project 1.18: Vision-Based Detection of Bridge Damage Captured by Unmanned Aerial Vehicles

Vision-Based Detection of Bridge Damage Captured by Unmanned Aerial Vehicles Project 1.18 Project Summary Bridge inspection is a vital component of any bridge management strategy of a state DOT. Significant funds are allocated to keeping the over 600,000 bridges in the U.S. safe. A routine bridge inspection is the most common type of inspection and […]

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 […]

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 2.17: Design and Development of High-Performance Composites for Improved Durability of Bridges in Rhode Island

Design and Development of High-Performance Compositesfor Improved Durability of Bridges in Rhode Island Project 2.17 Project Summary Transportation infrastructure is the backbone of our economy. But the current condition of America’s deteriorating transportation infrastructure network has raised serious concerns on safety, quality of life, and economic impacts. According to the recent American Society of Civil […]

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 1.17: Determining Layer Thickness and Understanding Moisture Related Damage of State-Owned Roads Using GPR and Capturing Such in a GIS-Based Inventory

Determining Layer Thickness and Understanding Moisture Related Damage of State-Owned Roads Using GPR and Capturing Such in a GIS-Based Inventory Project 1.17 Project Summary The Rhode Island Department of Transportation (RIDOT) has a significant inventory of state-owned roads of which layer thickness and moisture related damage is uncertain. Discrete methods of assessment like coring and […]

Project 3.15: Nonstructural approaches to reduce sediment and pollutant runoff from transportation

Nonstructural Approaches to Reduce Sediment and Pollutant Runoff from Transportation Infrastructure in Urbanized Areas Project 3.15 Project Summary Stormwater management is a critical component of transportation infrastructure and reduces sediments and pollutants delivered to waterways. The primary goal of this proposed study is to assess the performance and cost-benefit of including enhanced street cleaning program […]
