NJDOT Research Projects Receive High Value Research and Supplemental Awards by the AASHTO Research Advisory Committee

The Bureau of Research, Innovation and Information Transfer (BRIIT) is active in many national transportation efforts, including the American Association of State Highway Transportation Officials (AASHTO). Dr. Giri Venkiteela, Research Scientist, BRIIT, is the Vice Chair of Region 1 of AASHTO’s Research Advisory Committee (RAC) that serves the Special Committee on Research & Innovation (R&I).

In late July 2024, he attended the RAC’s National Meeting in Columbus, Ohio and accepted two awards on behalf of the New Jersey Department of Transportation.


Every year, the High Value Research Task Force of AASHTO RAC holds a national competition to find four “high value” research projects from each of the four AASHTO regions in the country. In 2024, two research projects sponsored and managed by the New Jersey Department of Transportation were recognized nationally with awards.

Several experimental and numerical research activities were carried out to assess the mechanical properties and long-term durability of Advanced Reinforced Concrete materials

The first project, Advanced Reinforced Concrete Materials for Transportation Infrastructure, was recognized as one of top 16 projects in the country and was managed by Dr. Venkiteela. The Principal Investigator for the study was Dr. Matthew Bandelt from the New Jersey Institute of Technology (NJIT) and championed by NJDOT’s Bureau of Materials.

Transportation infrastructure systems must resist conditioning from the natural environment and physical demands from service loading to meet the needs of users across the state. Reinforced concrete, which is widely used in bridge decks, pavements, super- and substructures, and other systems, deteriorates under environmental conditioning due to electro-chemical processes that cause expansive mechanics stresses at various length scales (e.g., reinforcement corrosion, freeze-thaw, etc.), leading to costly and timely durability and maintenance challenges.

The project report, which provides a background on the state-of-the-art of advanced reinforced concrete materials that are being investigated to improve reinforced concrete transportation infrastructure. A series of experimental and numerical research activities were then carried out to assess the mechanical properties and long-term durability of these systems. Results show benefits across a range of metrics and have the potential to substantially improve the in-service behavior of reinforced concrete transportation infrastructure.

Methods to preheat an excavated pothole prior to repair were described to improve the interface bonding between existing pavements and hot filling material.

The second project, Innovative Pothole Repair Materials and Techniques, was recognized in the Maintenance, Management, and Prevention supplemental categories and was also managed by Dr. Venkiteela. Separate research reports were prepared for asphalt (Volume I) and concrete structures (Volume II). The Principal Investigator for the study was Dr. Hao Wang from Rutgers-Center for Advanced Infrastructure and Transportation.

Pothole repair is one of the most important and frequent maintenance activities for highway agencies. Significant amounts of costs and resources are spent in pothole repair for material, labor, equipment, and traffic control. Cost-effective pothole repair methods can reduce or eliminate the possibility of re-patching and save future repair costs. The good condition of pothole repair with less cracking will also prevent reflective cracking when asphalt overlay is placed. Preheating the excavated pothole prior to repair has been found to improve the interface bonding between existing pavements and hot filling material, which can help enhance the overall performance of asphalt patches.

The long lifespan of a durable patch will reduce travel delay due to work zone and safety risk of highway users and workers. They will better preserve the condition of highway infrastructure and provide better service to the traveling public. The feasible usage of recycled materials can reduce the production of new material, which can contribute towards a more sustainable approach of roadway repair with economic and environmental benefits.

NJDOT’s Research Showcase Recognized as Best Virtual Event by AASHTO Communications Committee

The AASHTO 2023 Best Virtual Event Award recognizes a special event that is held virtually or that includes a virtual component.

AASHTO’s Committee on Transportation Communications – known as TransComm – sponsors an annual skills awards competition to promote the sharing of best practices and to recognize outstanding communications efforts. In October 2023, NJDOT Bureau of Research representatives Amanda Gendek and Pragna Shah accepted the 2023 AASHTO TransComm Skills Award in the Virtual Events Category for NJDOT’s 24th Annual Research Showcase. 

The NJDOT’s Bureau of Research Annual Research Showcase has been held since 1999 and provides an opportunity for the state’s transportation community to experience the broad scope of research initiatives and technology transfer activities conducted by their university and consultant partners. In addition to convening transportation professionals and researchers, the Showcase helps to emphasize NJDOT goals and objectives, share knowledge, and recognize the outstanding and inspiring research being done in the state.

The threat of COVID-19 transmission during the pandemic led to the Research Showcase being held fully online in 2020 and 2021. These fully virtual events resulted in a much larger audience, and even attracted attendees from other state Departments of Transportation. In 2022, as in-person events returned, the NJDOT Bureau of Research sought to find an approach that would maintain that larger audience base.

The 24th Annual Research Showcase, held October 26, 2022, was the first “hybrid” Research Showcase held by NJDOT and allowed individuals to attend the event online, while also allowing those able to gather, network and celebrate in person. Convening in a hybrid format required some additional coordination with the event planning team from Rutgers and Civic Eye Collaborative, a media consultant firm to live-stream the day’s proceedings. In total, 117 virtual participants and 190 in-person participants attended the day-long event.

Whether attending “in-person” or “virtually,” the audience heard from the keynote speaker and panelists on the major theme of the event “Advancing Equity in Transportation.” 

The Showcase theme, “Advancing Equity in Transportation” served as the organizing framework for the keynote speaker and panelists during the morning plenary session. The keynote speaker, Keith Benjamin, Associate Administrator for Highway Policy and External Affairs at the FHWA, spoke about the USDOT’s efforts to advance equity, highlighting the Infrastructure Investment and Jobs Act and the Inflation Reduction Act and various funding and program initiatives to address equity in transportation planning, project development, and other activities, among other topics. A panel session then explored the perspectives of representatives from NJDOT, county government, and transportation management associations (TMAs) who shared examples of the equity initiatives underway in their organizations. Questions and discussion invited panels to further reflect on the challenges and opportunities for advancing equity in transportation in New Jersey.  

The Showcase included afternoon breakout sessions featuring research presentations that continued to address the equity theme as well as other mobility, infrastructure, safety topics in transportation being performed by research faculty, staff, and students and NJ agencies. Several awards were also presented in recognition of research accomplishments and implemented innovations. For a full description of the 24th Annual Research Showcase event, see this recap here.

The 24th Annual Research showcase was recognized with the AASHTO Award for its efforts to enhance accessibility through the virtual platform. In addition to live-streaming the plenary and breakout sessions, the video recordings of the event were posted on NJDOT’s Tech Transfer Video Library and all those who registered were notified of its availability — whether attending in-person or online. Subsequent direct email communications and social media posts have further broadened the audience of potential viewers. To watch recordings from this, and other Research Showcase events, visit the NJDOT Tech Transfer Video Library.

The theme of the 24th Annual Research Showcase was selected in recognition of the significant Federal and state efforts underway to advance equity; Executive Order 13985 established a “whole government approach” to advancing equity and opportunity at the Federal level (left). Dr. Shawn Wilson, then-Secretary of Transportation in Louisiana, headlined a roundtable discussion, “State DOTs: Creating Pathways to Equity” at the Transportation Research Board’s 2022 Annual Meeting (right).
