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 […]
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 […]
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 […]
