Identifying Risks and Incorporating Them into Bridge Asset Management Planning 2026

  • October 27th, 2026

Departments of transportation (DOTs) manage extensive bridge inventories while facing increasing pressure from aging infrastructure, extreme weather events, and evolving federal requirements for risk-informed asset management. The Federal Highway Administration (FHWA) requires DOTs to develop and maintain Transportation Asset Management Plans (TAMPs) that address risk management for National Highway System (NHS) pavements and bridges. Although […]

Bridge Pile Repair Using Underwater Fiberglass Reinforced Plastic (FRP) Jacket and Steel Reinforced Grout

  • April 18th, 2025

This study explored the feasibility and acceptability of using stay in-place fiberglass reinforced plastic (FRP) jackets and underwater steel reinforced grout for timely bridge piling repairs in Minnesota without dewatering. One of the goals of the project was to determine the current state of practice to this corrosion repair and inspection by researching other projects […]

Incorporating Nondestructive Evaluation Methods Into Bridge Deck Preservation Strategies

  • January 17th, 2025

The use of NDE and structural monitoring (SM) technologies for assessing bridge deck condition is becoming increasingly popular due to cost savings and extended service life from timely interventions. Traditional assessment relies on visual and sounding surveys, but NDE methods, such as those based on physical principles of stress-wave propagation, electromagnetic properties, and electrochemical and […]

Corrosion-Induced Major Tendon Failures in Post-Tension (PT) Concrete Bridges

  • November 12th, 2024

There are two types of PT tendons—bonded or unbonded—depending on the timing of installing the duct, tensioning the strands, and filling the ductwith grout. Injected filler materials afford additional corrosion protection by providing physical barriers to water and air, i.e., oxygen and carbon dioxide.Cementitious grout can also be beneficial, providing a high-pH environment to form […]
