Evaluation of the Bonner Bridge Girders: Assessing Residual Capacity, Prestressing Losses and Degradation of the 56 Year Old Members

Sponsor: NC Department of Transportation

Start Date: 1/01/21

End Date: 12/31/22

Abstract

The NCDOT is in the process of deconstructing the 56 year old Bonner Bridge. This deconstruction provides an opportunity to evaluate the aged girders of the bridge and to compare their performance to load rating calculations. Such a comparison will provide a better understanding of the accuracy and assumptions associated with prestressing losses and will allow for refinements to the load rating procedures. This project focuses on a complete performance evaluation of the Bonner Bridge girders including full-scale load testing of 9 of the 61 ft. by 45 in. deep AASHTO Type III girders. The load testing will be conducted in the Constructed Facilities Lab (CFL) located at North Carolina State University. The research will provide recommendations for updates to the NCDOT Structures Management’s Manual guidelines. These assessments will also include directly evaluating the current amount of stress (after losses) in the girder prestressing steel; the condition, strength and stiffness of the concrete materials; and the location and extent of damage and repair of the girders.

Abstract

A project focused on the strengthening of reinforced concrete columns under reverse cyclic loading is proposed. Concrete columns will be produced with integrated foundations and will be strengthened with various types of Fiber Reinforced Polymer strengthening systems. The strengthening will be focused on flexural strengthening through confinement and on shear strengthening through external FRP stirrups. All columns will be loaded under reverse cyclic load histories in the presence of axial load. The goal of the program will be to investigate whether various systems can meet building code requirements for FRP strengthening systems.

Fiber Reinforcement for Latex Modified Concrete Overlays

Sponsor: NC Department of Transportation

Start Date: 8/01/19

End Date: 7/31/21

Abstract

A large number of bridge deck rehabilitations are performed each year in North Carolina. Latex Modified Concrete (LMC) and LMC–Very Early Strength (LMC-VES) are frequently used in these rehabilitations because these materials provide reasonable installed performance and allow for a rapid return to service. Over the last 5 years, the NCDOT has completed an average of about 25 overlays per year using LMC or LMC-VES materials. The vast majority of these projects are highly successful. However, despite comprehensive NCDOT guidelines and specifications (such as PSP003 and PSP004), substantial cracking is sometimes observed in these overlays shortly after installation. Prior research funded by NCDOT has indicated that if placement and curing follows proper construction procedures, then the primary causes of cracking (such as shrinkage and plastic shrinkage) in LMC and LMC-VES materials are unlikely to develop. However, other secondary mechanisms can potentially cause cracking, including vibration of the structure during casting and curing, temperature changes during casting, and slight differential settlement/deflection of supporting decks as overlay placement progresses across a bridge. These suspected secondary causes of cracking are difficult (or impossible) to mitigate in practice. In practice, it can also be difficult to completely enforce proper construction procedure, which can lead to some shrinkage cracking. For example, fogging above fresh LMC-VES is allowable, but allowing water to accumulate on the material during placement and finishing is not – the distinction is sometimes difficult to monitor and enforce in the field.

Durability of Pipe Materials in Soils

Abstract

A large number culvert pipes are installed every year in North Carolina. While the loading and structural requirements for these pipes are considered during the selection process, the exposure condition of these culverts receives less attention. Many pipe choices exist including reinforced concrete, galvanized steel, aluminum, aluminized, and various types of plastic. Choosing the right pipe for the right installation is a non-trivial task that carries significant financial impact. Factors such as structural capacity, environmental durability, anticipated life-span, required pipe size, site conditions, and available construction expertise are all important when selecting a pipe. Existing NCDOT selection tables provide some limited guidance, but often result in highly-conservative selections being made, particularly from the perspective of matching pipe materials to site environmental conditions. Selection of the wrong pipe material (or an overly-conservative pipe material) can result in significant excess cost. If materials degrade too quickly, costly re-work is required, and additional costs and risks may be incurred due to reduced performance of the degraded pipe. If high-cost and high-performance materials are selected in areas where they are not needed, then initial construction costs can increase dramatically. For example, in many situations, aluminized corrugated steel pipe can likely provide the same useful service life as corrugated aluminum pipe at a dramatically reduced cost. Aluminum pipe may be justified in regions with salt-water exposure, however, it is likely an over-conservative choice for regions where contact with salt will be incidental. Accounts from NCDOT personnel have indicated widespread use of aluminum pipe in regions where it is likely not needed (i.e., regions with limited salt exposure).

Abstract

Abstract: The NSF IUCRC for Integration of Composites into Infrastructure (CICI) is specialized at innovating advanced fiber-reinforced polymer (FRP) composites and techniques for the rapid repair, strengthening or replacement of highway, railway, waterway, bridge, building, pipeline and other critical civil infrastructure. The Center consists of West Virginia University (WVU) as the lead institution in the current Phase II, with North Carolina State University (NCSU), the University of Miami (UM), and the University of Texas at Arlington (UTA) as partner university sites. CICI is currently establishing an international site at the Center for Engineering and Industrial Development (CIDESI) in Queretaro, Mexico, through a collaboration between NSF and the National Council of Science and Technology (CONACYT) in Mexico. The primary objective of the Center is to accelerate the adoption of polymer composites and innovative construction materials into infrastructure through joint research programs between the university sites in collaboration with the composites and construction industries. In Phase III, CICI aims to broaden its scope of research in composites to include: 1) nondestructive testing methods; 2) manufacturing techniques, such as 3D printing; 3) inspection techniques, such as the use of drones with high resolution cameras; 4) in-situ modifications of infrastructure systems, resulting in enhanced durability and thermo-mechanical properties; and 5) cost-effective recycling of high value composites, enabled by the addition of CIDESI.

Mechanically Fastened CFRP to Retrofit Existing Prestressed Concrete and Steel Bridge Beams

Sponsor: NC Department of Transportation

Start Date: 8/01/17

End Date: 12/31/20

Abstract

Prestressed concrete C-channels and cored slabs, and steel beams of various shapes and forms make up a significant percentage of the common bridge superstructure systems used by NCDOT. Many such bridges are in varying states of distress and require retrofit to extend their useful service life prior to major rehabilitation or superstructure replacement. The challenge is to develop retrofit techniques that are durable, easy to install, monitor and maintain, and that may be applied to the range of prestressed concrete and steel beam types. Critically, NCDOT must also be able to rate the proposed retrofit using approved AASHTO methods before it may be applied in the field. In many cases the retrofit may be considered temporary since the bridge may be scheduled for replacement in the near future. Temporary strengthening is intended to provide the ability to maintain a sufficiently high operating rating to keep the bridge functional while replacement is scheduled. In lieu of an acceptable retrofit, the bridge may need to be load posted or closed, often resulting in significant detours and disruption.

Abstract

Traditional concrete protective structures encountered by ground forces typically have unconfined compressive strengths of between 3,000 to 6,000 psi. Recent advances in concrete technology have resulted in new concrete materials with compressive strengths of 30,000 psi or greater. No field instrument currently exists that can simultaneously determine the compressive strength, thickness, and rebar configuration of concrete structures across today’s wide range of possible compressive strengths. In STTR Phase I/II efforts, NLA Diagnostics LLC (NLAD) developed a prototype instrument that measures both compressive strength and concrete thickness up to 33,000 psi and 6 ft, respectively. NLAD has also mapped out a technical course to locate rebar within the concrete. This proposed project will take input from military operators to improve packaging of the existing technology and to implement a rebar mapping capability in order to enhance military capabilities to defeat concrete protective structures, accelerate the ability to deploy concrete characterization instruments with operating forces, and reduce the technical risks associated with engaging concrete protective structures in tactical situations.
