Successful implementation and effectiveness of monitoring systems requires good understanding of (1) structure being monitored, (2) existence of various monitoring technologies and their advantages and limitations, (3) monitoring process and (4) roles of involved parties. In the case of tunnels, lack of understanding of …

One of the earliest and most essential decisions that must be made in any infrastructure project is the selection of which project delivery method (PDM) to use. Since the choice of the PDM will dictate the language in the contract and the timing of its signing; state DOTs, local agencies, and tribal governments must make…

The researchers will generate a proposed parameter and recommended thresholds that would allow asphalt mixture suppliers to determine maximum RAP contents based on ex…

The primary goal of this proposal is to develop modeling approaches for the beneficial use of raw and stabilized sediments in engineering applications. First, a robust material characterization and strength laboratory testing program will be performed on specimens of raw and stabilized dredged sediments. These results wi…

In this study, proven pavement preservation treatments are proposed to be re-engineered using innovative materials that can better withstand the environmental and traffic loading conditions of the future.  In addition, recycled materials are proposed to be introduced to help reduce the carbon footprint of the pavement p…

The primary goal of this project is to research post-fire damage assessment of reinforced concrete tunnel liners and provide recommendations on damage assessment procedures for application in practice. The recommendations will cover the type of data to be collected after a fire event and how the data should be processed …

The primary goal of this proposal is to develop cost-effective standard open rib SOBD demonstrating similar performance as CRD.

The new design specifications for open rib SOBD to be developed in this study are expected to be incorporated into the AASHTO Bridge Design Specifications. Additional companion design gui…

The primary goal of this proposal is to evaluate the compatibility of different plastics within asphalt and evaluate the resultant asphalt binder and mixture performance of the plastic-modified material.

The intended outcome of the project is to develop a new material that would provide both a structural material …

The primary goal of this project is to analyze the failure of different types of transportation signage during Hurricane Maria. The specific objectives are:

• determine the causes of signage failure
• suggest improvements to the design and construction to avoid or reduce…
  

The primary goal of this proposal is to analyze pedestrian bridges that were damaged or collapsed during Hurricane Maria. The specific objectives of the project are:

• Develop an inventory of pedestrian bridges that were damaged or collapsed due to the hurricane and document the type of failures exp…
  

The primary goal of this project is to analyze motor vehicle bridges that were damaged or collapsed during Hurricane Maria. The specific objectives of the project are:

• develop an inventory of bridges that experienced damages or collapsed
• determine the causes of failu…
  

Current asphalt design procedures are solely based on volumetric principles and lack a valid methodology to ensure performance of the asphalt mixture considered during design.  This research focuses on a state of the art practice called Balanced Mixture Design (BMD), where the gradation and optimum asphalt content are n…

Rapid-repair cements are important to extending the life of infrastructure. Damage occurs to concrete systems because of poor construction quality, accidents, severe environmental conditions, and general wear and tear. Using rapid-repair materials allows agencies to repair the infrastructure without causing un…

The primary goal of this project is to understand the combined impact of corrosion and earthquake hazards on existing bridges, and the impact of repairs using cementitious composites on the vulnerability of bridges to these hazards. This will be achieved by establishing a probabilistic framework that can then be used to …

The overarching aim of the research is to explore and establish the ability of large-amplitude, forced vibration testing to reveal the current performance and forecast the future system performance of bridges, with the consideration of dynamic soil-foundation-structure effects. With the ability to perform reli…

The electrified pavement in the charging lane provides in-motion power supply for electric vehicles. However, the service life of pavement may be negatively impacted due to the complicated structure design for achieving the function of dynamic wireless charging. This primary goal of this research is to develop new design…

The Port Authority of NY & NJ is a leader nationally in incorporating climate resilience into major capital projects at the design phase. The agency has adopted comprehensive design guidelines to improve the resilience of agency infrastructure. However, the agency is interested in documenting leading practices at pee…

The goal of this research project is to validate and provide a basis to improve and refine a novel de-icing system for stay-cables. This autonomous de-icing system shows significant potential to cost-effectively remove ice build-up without damaging the protective system of the underlying stay-cable. However, currently th…

The public desires less disruption to highway services in addition to cheaper and more aesthetically pleasing structures. To meet these needs, engineers are continuously pushing the limits of current designs. One way to decrease the costs of an expensive structure is to limit the number of supports, provide longer span l…

Pervious concrete has been increasing in popularity as a potential solution to reduce the amount of impermeable surface area associated with sidewalks, reduce puddling, and potentially slow storm water surface high-flow rates. As important as these benefits are to surface runoff mitigation, there are concerns with the ab…

The geosynthetic reinforced soil integrated bridge system (GRS-IBS) is an innovative alternative to conventional bridge technology that utilizes closely spaced layers of geosynthetic reinforcement and compacted granular fill material to provide direct bearing support for structural bridge members. Using this technology, …

The primary objectives are two develop two formulations, one suitable for casting slabs with least amount of creep and shrinkage and eliminate cracking due to restrained time-dependent strains and the second for specialized uses in grouting and gluing for pre-cast construction. The first part of the research will utilize…

Collisions between over height vehicles and bridges occur about 1,000 times per year in the United States. Collision damage to bridges can range from minor to catastrophic, potentially requiring repair or replacement of a bridge beam. For prestressed concrete beams, the traditional repair methods are strand splices and F…

This project for the New Jersey Department of Transportation (NJDOT) was designed to analyze potential closure of uncapped New Jersey landfills using dredge material from existing confined disposal facilities (CDF).
