The NJ State Transportation Innovation Council (NJ STIC) convened its 3^rd Quarter Meeting on September 27, 2023 at the NJDOT Bordentown Training Center for Excellence. This in-person event provided an opportunity for attendees to tour the newly opened state-of-the-art training center. An agenda for the meeting was distributed in advance of the event.

Welcome Remarks and Tour of Training Facility. Brandee Sullivan, NJDOT Innovation Coordinator, greeted those in attendance and opened the meeting. Assistant Commissioner Michael Russo gave welcoming remarks, noting that the STIC meeting was the first held “in-person” since the outset of the pandemic. He gave an overview of the day’s agenda and its featured speaker. He noted that Sudhir Joshi, from the Bureau of Statewide Strategies, would assume CIA Team Lead for the Planning and Environment Team.

Ms. Melissa Boyer from the Bordentown Training Center for Excellence spoke briefly about NJDOT’s acquisition of the former property of the New Jersey Department of Military and Veterans Affairs in 2016 and the substantial rehabilitation investments made to convert three buildings and the surrounding land into the transportation-focused training complex. Those in attendance were then divided into separate teams for guided tours that were provided by Ms. Boyer and Eric Walters that included an opportunity for a “hands-on” sampling of the facility’s truck driving simulators.

FHWA Updates. After the tour, Christopher Paige, Innovation and Community Planner in the FHWA NJ Division Office, gave a brief update. He noted that the FHWA had issued its EDC-7 Baseline Report in July 2023 which conveys the innovations and goals for deployment being set by the various states. He highlighted that several FHWA Innovation Exchange Webinars have been delivered since the EDC-7 launch to introduce select topics such as Nighttime Safety and Strategic Workforce Development and available resources. As with prior rounds, EDC-7 will have a two-year cycle, but the period of performance was adjusted to run through May 2025. The first progress report cycle will be due in April 2024. He provided an overview of several resources available through the FHWA’s Center for Accelerating Innovation (CAI) website which leads the national STIC program.

Core Innovation Area (CIA) Updates. The meeting continued with short presentations from Core Innovative Area (CIA) leaders who provided updates on the status of the various innovative initiative topics being advanced during EDC-7. Update reports were given by the various CIA Teams on Safety, Infrastructure Preservation, Mobility and Operations, Organizational Improvement and Support, and Planning and Environment.

Featured Presentation – SJTPO Innovative Approaches to Traffic Safety Education. The South Jersey Transportation Planning Organization (SJTPO) has developed a series of traffic safety education programs to teach the public about traffic safety. The programs are designed to bring awareness to the many traffic safety risks presented to drivers, passengers, bicyclists, and pedestrians on area roadways and teach simple ways to improve safety. Robert Clarke, SJTPO Traffic Safety Specialist, described the various traffic safety education programs, highlighting the length of each program and typical audience. In describing the several trainings, he explained how they were designed to appeal to unique needs, interests and specific age groups such as high school, elementary, and middle school students, adults, and vulnerable older drivers. For example, a driving simulator program was targeted to teens in a probationary period, or the basic physics of driving were emphasized in a training targeted to high school math and physics students. During his talk, Mr. Clark also touched upon the various federal and state funding sources and resource commitments made to sustain SJTPO’s Safety Education and Outreach Program.

Announcements and Reminders

NJDOT Safety Resource Center. Jeevanjot Singh, Section Chief, gave an overview of the NJDOT Safety Resource Center (SRC) and its activities. Ms. Singh explained that NJDOT’s most important mission is ensuring safety – the safety of our customers and the assets that the agency builds. Ms. Singh noted that the SRC is envisioned as a one-stop destination for roadway safety-related information, noting that the SRC seeks to connect safety stakeholders with information about safety projects and programs, funding and grant opportunities, trainings from industry experts, safety campaign materials, technical assistance and other resources.

The SRC has launched a training program and, to-date, nine “Lunch & Learn” sessions have been held with more planned for the future. The SRC is also looking to develop longer in-depth trainings on select topics such as the “safe systems” approach. The SRC is expected to launch a website and a SRC LinkedIn page shortly and develop public campaigns to promote a positive safety culture for all road users.

Ms. Singh spoke about the role that the SRC plays in the implementation of the Strategic Highway Safety Plan, among other topics. She encouraged those in attendance to register for the NJDOT Safety Summit event planned for October 24th at the College of New Jersey.

2023 National Build a Better Mousetrap Award “Bold Steps” Winner: NJ’s Route 71 Over Shark River Road Diet Project. This NJDOT bridge rehabilitation and road project was recognized as the year’s “Bold Steps” Award winner in the 2023 National Build a Better Mousetrap Award Competition. Each year, the FHWA honors state, local, and Tribal agencies for devising innovative solutions to improve transportation programs. Mrs. Sullivan congratulated Gerald Oliveto, P.E. and his team for receiving the national award which developed a breakthrough solution to preserve an old bridge while improving safety and saving taxpayer dollars.

In announcing this year’s award winners, FHWA produced a video explaining the Bold Steps Award and offering a description of the Route 71 Over Shark River Road Diet project which can be accessed here. The FHWA noted that the innovation not only improves transportation performance, but offers a model and transferable solution for other agencies.

Presentation: Route 71 Over Shark River: Road Diet & Safety Improvements Project. Gerald Oliveto, P.E. then gave an in-depth presentation about the award-winning project, explaining the history and location of the bridge and the challenges that NJDOT had to quickly confront after a span-lock failure in September 2021 disrupted the drawbridge’s operation, affecting roadway usage and maritime traffic patterns. Mr. Oliveto explained how the Route 71 drawbridge safety features – opening and closing sequences – were designed to operate to further help set the stage for understanding the challenges and urgency of the project.

He described several interim repair options that were examined for their cost and benefits before the preferred road diet option was selected as a near-term solution. He emphasized that design and implementation of the preferred solution was the product of effective teamwork and extensive internal coordination (e.g., regional operations, structural engineering, traffic engineering, signage, office of government and community relations, etc.).

Mr. Oliveto described how NJDOT implemented a road diet across the bridge, which allowed the Department to address safety issues. Traffic over the bridge was reduced from one northbound lane and two southbound lanes to one lane in each direction. With the lane configuration reduced to one lane in each direction, NJDOT was able to extend bicycle lanes that previously terminated in Avon-By-The-Sea across the drawbridge into Belmar.

His presentation highlighted a key design feature that was used to extend the bike lanes over the bridge. The extended bicycle lanes were accomplished using an innovative fiber-reinforced-polymer mat on the bascule span. The mat is the first of its kind in New Jersey and provided a safe crossing of a steel-grid deck for bicycles. Previously, bicyclists had needed to dismount and walk their bicycle across the bridge. The extended bicycle lanes provided connectivity between both downtown areas and an area heavily utilized by bicycle traffic year-round.

Mr. Oliveto’s talk described several design and community coordination features that were integrated into the project to build needed municipal and community support. His talk made clear the importance of communications, early and often, and working with the affected communities throughout the process to explain the logic behind the selection of the road diet option and identifying other design features (e.g., painted crosswalks, signage) that would be welcomed by the local communities. His talk touched upon various communications and coordination activities that were put into place, including the NJDOT’s Office of Communications use of social media and videos to keep the public informed about the road diet project, and the NJDOT’s Office of Mobility working with GPS companies about routing changes to avoid adverse routing of vehicles onto residential streets, among others.

NJ STIC Exemplary Council Member Award. Assistant Commissioner Russo presented Shivani Patel, CIA Team Lead for Infrastructure Preservation, with the NJ STIC Exemplary Council Member Award as its first-ever recipient. The award recognizes her strong leadership as CIA Team Lead since assuming responsibility and her instrumental role in championing the Environmental Products Declaration initiative by developing an SME team and hosting coordination meetings

Featured Presentation – NJDOT Sustainability Initiatives. 

Three presentations were given on NJDOT Sustainability Initiatives.

Presentation # 1 – Foamed Glass Aggregate.  Kimberly Sharp, NJDOT Bureau of Geotechnical Engineering and Geology, spoke about Foamed Glass Aggregate (FGA) which is made from 100 percent recycled glass. Use of the material reduces waste in landfills, alleviates the burden on waste management infrastructure, and promotes a more sustainable approach to handling waste. CO2 emissions and energy use for production is 50 percent less than for other lightweight aggregates used by NJDOT. Due to FGA’s light weight, fewer trucks are needed to transport it, which keeps heavier trucks off the road, and reduces emissions and congestion.

Lightweight and durable, the material is non-leaching, rot-resistant, and non-flammable.  Ms. Sharp discussed the manufacturing process and the various applications of FGA in NJDOT projects, including as fill behind retaining walls and abutments, around utilities, tunnels and culverts to lighten loads, underneath roads to raise the profile in areas of flooding. These projects have saved millions of bottles from the landfill.

In the future, FGA may be used for flood mitigation (underground reservoirs), noise walls, as backfill for Mechanically Stabilized Earth (MSE walls), and in rehabilitation projects for abutments and wall reconstruction.

Ms. Sharp mentioned another process they are investigating that makes pellets from plastic bags and places the material in concrete.

Presentation #2 – NJDOT Initiatives for Sustainability in Pavements.  Robert Blight, NJDOT Pavement and Drainage Management Technology, talked about innovative pavements including rubber pavements made from scrap rubber tires, recycled asphalt pavement, and recycled plastic waste. The use of these materials has the potential to reduce pavement life-cycle costs, greenhouse gas emissions, energy consumption and noise.

Recycled scrap rubber tires is an engineered waste product the use of which could reduce pollution of water and air from landfill storage. Asphalt rubber is ground tire rubber incorporated into open-graded asphalt pavement material. Some applications recycle up to 1,000 tires per lane mile. Winter maintenance became an issue for NJDOT and application in roadways was paused, but the material could be used on shoulders or for parking lots.

NJDOT used an asphalt rubber gap-graded mixture on a project in 2014 which is still performing well, and asphalt rubber binder in asphalt rubber chip seal was used on a project in 2018.

Reclaimed asphalt pavement (RAP) uses asphalt milled during resurfacing projects. Some concerns include performance issues with the binder and the need to process the material to achieve uniformity rather than adding directly to pavement material. A 2012 project that used a high-RAP mixture is still performing well.

There has been a lot of research into using waste plastic in pavements looking for long-term performance and sustainability. NJDOT has an ongoing research project with Rutgers exploring use of plastic waste as a modifier in pavement materials. Safety, health and environmental concerns with using plastic requires reliance on research and engineering expertise.

Presentation #3 – Sustainable Research Projects.  Mansi Shah and Kamal Patel, NJDOT Bureau of Research spoke about current research projects on sustainable materials. Ms. Shah discussed the research process for the Implementation of Pervious Concrete Sidewalks in New Jersey. Ms. Shah described the material which is made of cement, aggregates, water, and admixtures, poured over a stone reservoir that temporarily stores rainwater before infiltration to the subsoil. The material plays a role in stormwater management by reducing puddling and slowing stormwater surface runoff. The implementation phase involved a pilot demonstration sidewalk project in Montgomery Township. Regular maintenance of the material is required to keep the voids free of debris.

Ms. Shah noted that the Bureau of Research seeks to conduct research studies to explore the possibility of recycling scrap tires for use as aggregate in concrete and asphalt. This process addresses a growing environmental problem and threat to health. Ms. Shah suggested collaboration with Robert Blight on this area of mutual interest.

Mr. Patel discussed Energy Harvesting from Roadway and Bridges as an alternative to electricity produced by burning fossil fuels. Energy harvesting uses the current transportation infrastructure to generate electricity for various transportation applications such as powering sensors and other lighting as well as wireless data transfer devices to monitor traffic data and infrastructure. The research explored photovoltaic materials and Piezo electric materials. In the first project phase, researchers explored the configuration of solar panels on noise barriers and found an optimal configuration for maximum power output.

The second project phase employed piezoelectric sensors embedded on bridge structures. Energy harvesting can be achieved by compression caused by traffic traveling over the sensors, or by vibration, caused by traffic loads and winds, detected by sensors attached to the bridge structure. The research focused on sensors attached to bridge structures and what resonant frequency would yield higher voltage outputs. Lab testing and full-scale testing were conducted.

NJ STIC Meeting notes including presentations and recordings can be found in the NJ STIC section for the website (https://www.njdottechtransfer.net/nj-stic-meetings/)

Sal Cowan spoke about the new NJDOT Bordentown Training Center. In seeking to address the need for a workforce that is right-sized, properly trained and properly equipped, NJDOT has developed a first-class training facility and a business unit dedicated to training the technical workforce. The training facility will be used specifically by Operations. However, in describing key elements of the facility, Mr. Cowan emphasized that it will be available to serve the entire Department.

Mrs. Sullivan spoke about the 10th anniversary of the 2023 American Council of Engineering Companies Design Summit. The Summit gathers people from various areas of the transportation design industry.  This year’s theme was innovation and the event featured several presentations on EDC-7 topics and the role of NJ STIC, and a discussion on the barriers to innovation.

She added that there are free trainings on EDC-7 topics through the Local Technical Assistance Program at Rutgers-CAIT. She shared links to an upcoming schedule of trainings and noted that there will be more trainings  available in the future.

Featured Presentation – Ultra High Performance Bridge Preservation.  Jess Mendenhall, Project Engineer, and Samer Rabie, Principal Engineer from NJDOT’s Structural Value Solutions Unit presented on the design, construction, and evaluation of Ultra-High Performance Concrete (UHPC) Bridge Deck Overlays for NJDOT.  The NJDOT Structural Value Solutions unit has been exploring the use of UHPC in bridge preservation and rehabilitation projects, an emerging application of UHPC in the United States. Bridge deck overlays were placed on four New Jersey bridges.

Mr. Mendenhall described the composition of the material and its superior mechanical and durability properties. He observed that the the advantages to using the material include preservation of bridge elements in good or fair condition and extension of the service life of bridge decks yielding potential life cycle cost savings. The disadvantages include the cost of the material, limited contractor experience with use of UHPC as an overlay, and the workability of the overlay mix. The cost of using UHPC tends to be higher than that of conventional overlay, and lower than replacement of the bridge deck.

Fully understanding the existing bridge condition and determining the remaining service life of primary structural components (i.e., the deck, superstructure and substructure) are crucial in choosing whether to proceed with deck preservation using UHPC overlay or conventional deck replacement and rehabilitation.  Mr. Mendenhall provided an illustrative example of how a life cycle cost analysis can help support the decision of preservation versus reconstruction of a bridge.

Mr. Mendenhall described the research process and criteria used for the selection of the four bridges, among other candidates, for advancement into design and construction for UHPC Bridge Deck overlay to permit testing of UHPC.  Eight candidate structures were fully evaluated and tested before the four bridge structures were advanced. In this stage, testing was performed on current deck conditions.  All structures included in the program were evaluated for suitability based on the structural evaluations, chloride content within the deck, feasible construction stages, traffic analysis results, and existing overlay depths. Chloride content was obtained from concrete core samples on each bridge deck.

The bridges that were ultimately selected varied in their age, size and design. All the bridges had asphalt overlay.  The selected bridges for the pilot program were in good condition to leverage the perceived long life-span of UHPC and not allow other factors to limit the potential service life.  Two of the bridges selected were less than 10 years old, and two bridges were 30-40 years old.

In the design phase, the finished bridge deck elevation was required to match the existing elevations. Various solutions were found for the four bridges including a thin overlay, a 1.5″ overlay with an asphalt topping, and a 2.75″UHPC overlay with no asphalt topping. Design solutions avoided excessive UHPC overlay to control costs.

Mr. Mendenhall described the preferred surface conditions for the application of UHPC and the rationale for a hydrodemolition specification to remove the upper half inch of the existing deck surface. This process results in a roughened surface with exposed aggregate which is the ideal bonding surface for UHPC that limits microfractures that can affect bond performance compared to other technologies such as diamond grinding and milling.

During his presentation he also spoke about the staging of construction into two stages for all bridges, highlighting specifications and joint details to prevent water intrusion and provide structural continuity in the deck slab.  Exposed fiber finish was specified to promote bonding between stages of UHPC application to ensure an exposed aggregate finish suitable for UHPC application. He highlighted the need for full depth and reconstruction with UHPC to full depth at deck joints which can be susceptible to deterioration.

Samer Rabie discussed UHPC materials specifications and testing, specifications for construction processes, lessons learned, the evaluation process, and the focus of future assessments. He shared video examples of UHPC placement in the field and discussed design and construction special provisions, use of specialized equipment, mixing and application of UHPC, the importance of exposed fibers, the expertise required of the workforce and contractors, and proper curing and finishing, among other topics.

Several lessons learned were shared, including an expectation that NJDOT would seek in the scoping and concept development stage to identify project locations that could use UHPC as a final riding surface (rather than asphalt) to enable its evaluation, inspection and characterization for representative condition ratings for the future.  However, if an overlay is needed on top of UHPC for geometry or profile, the agency will consider BDWSC (Bridge Deck Waterproof Surface Course) or High Performance Thin Overlay materials.

To measure the existing conditions, the use of ground-penetrating radar (GPR) should be used to determine concrete cover, overlay thickness and reinforcement locations and to determine the causes of delamination.

Two special provision items will emphasize the use of surveys to inform depths of hydrodemolition and material qualities required for placement to ensure continuous operation and to specify watertight forms, top forms, minimum overfill, and surface grinding.

Mr. Rabie also outlined construction considerations and challenges in the application of UHPC and proper staging.  He described how UHPC slurry with no fibers was placed in air voids in response to surface defects before asphalt paving and emphasized that proper repair methods in contract documents should be defined to address aesthetic or structural anomalies.

Mr. Rabie also described in some detail the testing methods that have been used for annual evaluations for two bridges, including non-destructive impact echo testing and ultrasonic tomography, as well as physical sampling and lab testing. The ultrasonic tomography and impact echo testing indicated that the bond between UHPC and concrete substrate is sound and that the chloride content was within expectations.

In his concluding remarks, Mr. Rabie observed that the baseline testing was successful, with no significant defects encountered. NJDOT is considering installing UHPC overlays on newly constructed decks as well as decks with lower condition ratings for future projects. A deeper overlay (with deeper existing deck removal) will be regarded as a viable alternative for structures that need a major deck rehabilitation. NJDOT is also incorporating UHPC for several applications in the new design manual, including P&R.  In future studies, the team will seek to better understand deterioration rates of UHPC.  The presenters also responded to questions related to the approximate service life of UHPC and its tensile capacity.

Reminders and Updates.

Mrs. Sullivan (Chapman) announced that NJDOT received the 2022 America’s Transportation Award for Best Use of Technology and Innovation for the Implementation of Drivewyze on 647 miles of NJ’s Highways.

Mrs. Sullivan (Chapman) provided reminders on the online location of several resources that highlight the NJ STIC and other innovation topics funded through research and technology transfer activities, including:

• NJDOT Tech Transfer Website – http://www.njdottechtransfer.net/
• NJ STIC Website – https://www.njdottechtransfer.net/nj-stic/
• NJ STIC Meetings – https://www.njdottechtransfer.net/nj-stic-meetings/

She reminded the attendees to save the dates for the FHWA EDC-7 National Summit and the NJ STIC Caucus. The EDC-7 Summit will be held from February 14-16, 2023 as a virtual event, featuring some states that have used the initiatives successfully, and an Innovation Showcase. The Summit will be followed by the NJ STIC Caucus on February 22, 2023 from 10:00am-12:00pm. During the Caucus, the NJ STIC will discuss the opportunities and barriers of the new initiatives and consider what initiatives New Jersey should pursue.

STIC Incentive Program funds are still available for 2022 and more funds will be available soon for the coming year. The FHWA offers these funds, as well as technical assistance, to support the costs of standardizing innovative practices in a state transportation agency or other public sector STIC stakeholder. NJ STIC receives $100,000 each year. Mrs. Sullivan (Chapman) asked that the STIC network members communicate these grant opportunities through their networks. Local public agencies are eligible to apply. Find more information, including examples of allowable activities and prior recipients, here.

Mr. Russo provided closing remarks.
