BACKGROUND
Many new and emerging technologies, offering improved performance or effectiveness, are continually becoming ready for operational implementation. Some of these technologies have been developed through rigorous research and may have been demonstrated in “real world” applications. Some may have been gleaned from international technology scanning tours. Others evolved within practice but are not shared.
The purpose of the AIM is to identify and champion the implementation or deployment of a select few proven technologies, products or processes that are likely to yield significant economic or qualitative benefits to the users.
AASHTO’s Innovation Management encourages the sharing innovation practices nationwide.
WHO: The AASHTO Innovation Initiative accepts innovations for consideration from State and local Departments of Transportation, and organizational units of AASHTO. (AASHTO members include member departments and associate members). Additionally, private industry representatives may work with eligible submitters who have successfully used these innovative practices to nominate technologies. Applications may be developed by DOT partners (academia, industry, other associations, etc.); however, actual submissions must be proposed by one of the agencies listed above.
HOW: Learn more and complete the NOMINATION form that can be found here. All nominations must be submitted electronically. If you have any difficulty with your submission, please contact Glenn Page, gpage@aashto.org or (202) 624-5265.
The IUOE has named the hybrid apprentice program “Earn and Learn.” The first student cohort began class in January 2022.
Strategic Workforce Development, an FHWA Every Day Counts (EDC) Round 6 and 7 innovation, anticipates collaboration between government agencies, trade organizations, private agencies, and communities to prepare individuals for the construction workforce. The demand for workers in highway maintenance, construction, and operations is growing, as is the demand for new skill sets required for work with emerging technologies. The recruitment and retention of women and minorities in the construction sector is integral to the initiative. Through on-the-job training and supportive services program, NJDOT is exploring ways to work with contractors, contracting associations, and unions on shaping the future workforce, including programs aimed at increasing representation of women, minorities, and other disadvantaged populations in the construction and operations workforce.
We spoke with Lori Margolin, the Associate Vice President for Continuing Education and Workforce Development at Hudson County Community College (HCCC) and Greg LaLevee, Business Manager, International Union of Operating Engineers (IUOE) Local 825 for an update on their apprenticeship program entitled Earn & Learn.
Earn & Learn Program Background
The IUOE Earn & Learn program is an advanced manufacturing initiative supported by a NJ PLACE 2.0 grant. HCCC and IUOE Local 825 established the program in November 2021 through an articulation agreement. The program gives students the opportunity to be dually enrolled in the union apprenticeship program and HCCC, where they will earn an Associate of Applied Science in Technical Studies degree after they complete 60 credits.
During an 18-month period, participants earn 30 credits from on-the-job training and education provided by the union and are scheduled to earn the other 30 credits from HCCC over five semesters. They attend HCCC part-time, taking two classes per semester and earning six credits per semester on average. All classes are offered in a virtual modality.
Q. The Earn & Learn program has been operating for a little over one year. How is program implementation going so far?
HCCC Continuing Education and Workforce Development works with employers to provide training to meet a diversity of needs.
A. Implementing the program with this first cohort of students has been a learning experience for both the HCCC and IUOE Local 825, as this initiative is the first of its kind. Program implementation is going well overall, with challenges noted below. Twenty-four of the 30 students initially accepted into the program remain enrolled. Factors influencing departures included health issues and struggles for some with the academic or other program requirements. The program is on-track to initiate a second round of applications later this year for the spring 2024 semester.
Q. Are you making modifications to either the academic component or the hands-on training based on your experience in the first year of implementation?
A. As initially planned, students would earn an Associate of Applied Science in Technical Studies degree after they complete 60 credits. However, we have reconfigured the degree to more closely align with the construction industry; students will earn a degree in Technical Studies with a construction concentration.
The course work has been altered to be more directly relevant to the construction industry and to what students are learning at IUOE Local 825. For example, we have replaced some of the math and science courses more directly aligned with the HCCC construction management course work.
While all participants take the same coursework, some modifications are available to accommodate students on different pathways. For example, a student seeking to continue their studies at a four-year university should likely take a Calculus course, whereas those not wishing to continue their education beyond an Associate Degree may opt for other available math courses.
Q. What have been the key challenges you have encountered so far in the program implementation? How have you addressed those challenges?
The IUOE Training Center offers simulations to prepare for operating in-field equipment.
A. One of the main challenges can be scheduling as students must meet the demands of their on-the-job training, as well as their classroom instruction requirements. Construction jobs may be located far from one’s residence and/or require off-peak work hours, which compounds this scheduling challenge.
Many of the participants have not had recent experience with balancing academic demands with on-the-job training. Many of the students are 25 years of age or older and have not been enrolled in school for several years. For such students, re-entering the classroom can be a “culture shock,” and requires them to learn how to prioritize academic studies.
This is often an issue in adult learning so both a HCCC Student Success Coach and the IUOE Local 825 chief academic officer are vital partners in the program. Many HCCC initiatives include a Student Success Coach as a best practice to provide adult students with additional supports with navigating the college in terms of scheduling, instruction, and identifying resources to address other demands so they can attain success. The Student Success Coach often functions as a student advocate and navigator. The value of the Student Success Coach to the Earn & Learn program must be emphasized.
Q. What have been some key takeaways and lessons learned so far with the program?
HCCC and the IUOE are training workers for the construction industry, including highway construction.
A. Creating connections among the student cohort has been an important and contributing factor to students’ ongoing success. Students have been able to develop relationships virtually through class, as well as through the Earn & Learn in-person orientation. We also convened an in-person meeting with students after the first semester to discuss issues and challenges with the Earn & Learn program. The students receive both academic and emotional support and camaraderie from one another and benefit from cohort learning.
Also vital to identifying and addressing program challenges has been the open and clear communication channels established and nurtured between the HCCC Student Success Coach and the IUOE Local 825 chief academic officer.
We have learned that overall program flexibility is key as well. For example, to give students the greatest scheduling flexibility and to accommodate diverse comfort levels, they are given some choice with how their HCCC academic instruction is delivered. Specifically, for some classes student can take asynchronous online classes, or opt for synchronous instruction with a live instructor.
Q. What benefits have been achieved so far from the Earn & Learn program?
A. Many students are surpassing their own expectations for their performance in the program, which is wonderful to experience. As one student shared, “I didn’t think I could do school again.” Most are maintaining high GPAs. I feel that the personal growth experienced by these students will also translate into them becoming better members in the IUOE union and better employees.
Q. Are you aware of any other similar programs generating interest in the construction trade?
Students get “hands-on” time for operating heavy equipment at the IUOE Training Facility.
A. The Earn & Learn program is a bit unique. However, I believe the Carpenter’s Union is working on something with the state Community College Consortium for Workforce and Economic Development and they are referring to their training centers as technical colleges. Some of the other construction trades also have arrangements with higher education institutions, such as with Thomas Edison State University.
Other Construction-Focused Career Initiatives
Q. During our interview last year, the goal of bridging the gap between student age when graduating Vo-Tech (17 years) and entry into an apprenticeship (age 18 required) was discussed. You were trying to arrange for a direct entry from Middlesex County Vo-Tech to a union apprenticeship with IUOE Local 825. Have you gotten any traction on that effort?Are there other construction-focused career initiatives you want to bring to our attention?
A. Opportunities are never lost! We continue to work on advancing this goal with Middlesex County Vo-Tech of bridging student age when graduating Vo-Tech and apprenticeship entry with us. The Vo-Tech’s East Brunswick campus is located 2.5 miles from the IUOE Local 825 training center, so there is a genuine opportunity here for those students.
Ocean County has a heavy equipment program in their Vo-Tech and we [IUOE Local 825] had an initial meeting to learn more about that effort. We also had some of their students come to our training center for a site visit.
There are other exciting education-focused initiatives happening as well. For example, Local 825’s sister organization located in the Midwest has developed a mathematics curriculum for high school students that local districts can use. The curriculum speaks to how the student would resolve math questions as an operating engineer. IUOE Local 825’s academic officer is working to bring that curriculum to New Jersey, perhaps in collaboration with the non-profit Junior Achievement organization, which is focused on developing youth skills to promote economic success.
An innovative Rutgers initiative led by the Rutgers Youth Success Program (RYSP) in partnership with Rutgers Center for Advanced Infrastructure and Transportation (CAIT) recently received new funding through a PACE grant. The RYSP program will seek to place under-represented and justice-challenged young people in transportation and infrastructure careers. The grant will support development of a pre-apprenticeship program for Operating Engineers. HCCC will be the training partner for this 18-month program.
Middlesex County is home not only to Rutgers and IUOE Local 825, but also to many of the construction equipment dealers such as John Deere, Caterpillar, and Komatsu. However, there remains limited interaction between all these potential partners to discuss opportunities to diversify and strengthen the construction workforce.
Q. HCCC is a co-leader with Rowan College in the Construction Center of Workforce Innovation. Can you give us a brief update on that work? Do you collaborate directly with Rowan on these initiatives and, if yes, in what way?
A. This Construction Center of Workforce is part of the New Jersey Pathways to Career Opportunities (NJ Pathways), a collaborative program between the NJ Business & Industry Association (NJBIA) and the New Jersey Council of County Colleges. Year one work has been completed. There are ten centers for workforce innovation, including one focused on construction. HCCC is the administrative lead along with Rowan College of South Jersey for the construction innovation.
The Construction Center of Workforce is one of ten workforce centers partnering with the state’s community colleges.
HCCC’s efforts related to the Construction Center of Workforce Innovation, as well as through several other initiatives including the Earn & Learn Program, helped focus our successful work to expand the offerings in our construction management program. We have had an Associate Degree in construction management for a while, and now we also offer a one-year academic certificate requiring 34 credits and 2 proficiency certificates in either construction administration or construction technology requiring 13 or 14 credits. We also offer seven-to-nine individual courses that offer certification in specific areas of construction management. Students can opt to take one or two courses or all the offerings. If students opt to take these offerings as a noncredit course, they can transfer or articulate for credit in the HCCC Construction Management academic certificate or degree program.
HCCC also offers the opportunity to earn a National Institute of Certified Engineers and Technicians (NICET) certificate for the field of Asphalt Testing and other similar offerings, all of which have been very popular. In all, by offering these different degree and non-degree options, students are afforded flexibility to acquire skills that best meets their career advancement goals. This work also helps us advance equity goals as well, as students can learn at their own pace and effectively build their own career pathway beginning where they wish to start.
Q. Do you see any ways that NJDOT’s Civil Rights, Human Resources, or other units could engage with you to advance programs in NJ?
A. The State and NJDOT are seeking greater diversity, equity, and inclusion in the construction field and on job sites. To achieve this goal, we need to operationalize strategies that will encourage greater diversity among persons who are considering construction as a viable career path and who may apply for construction jobs. Incremental progress in this regard is possible if we work together. We must look beyond meeting a requirement for a specific number of diverse workers on a job site – instead we should focus attention on developing a plan to generate overall interest in the field and set mid-point goals toward achieving that plan.
On another note, generating interest for a career in heavy equipment operations among youth, especially among youth living in urban areas, is challenging as these individuals often have little exposure to our trade compared to those who reside in more rural areas and who may have experience or familiarity with farm and other heavy equipment. Working with the Junior Achievement organization may provide another pathway for us to identify a new generation of prospective heavy equipment operators and other construction workers.
We would welcome opportunities to sit at the table with NJDOT to advance careers in construction and are open to developing and refining training and education programs to meet the diverse needs of the workforce.

NJDOT’s Route 71 Shark River Bridge Preservation and Road Diet project has been selected as a regional winner in the 2023 America’s Transportation Awards Competition. The competition is sponsored by the American Association of State Highway and Transportation Officials (AASHTO), AAA, and the U.S. Chamber of Commerce.
The Route 71 Shark River Bridge Preservation and Road Diet project received honors in the Operations Excellence, Small category. This year’s regional winners were chosen from a selection of 19 projects nominated by nine states in the Northeast Association of State Transportation Officials (NASTO) region. The NASTO region’s winners will compete for the National Grand Prize, the People’s Choice Award, and $10,000 in cash awards that will be given by the winners to a transportation-related charity or scholarship program of their choosing.
After the Route 71 Drawbridge over Shark River between Belmar and Avon-by-the-Sea in Monmouth County suffered a mechanical failure in September 2021, engineers devised a cost-effective design and implementation solution that would preserve the drawbridge and keep it in safe operation.
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. Previously, bicyclists needed to dismount and walk their bicycle across 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 provides a safe crossing of a steel-grid deck for bicycles. The extended bicycle lanes provide connectivity between both downtown areas and area heavily utilized by bicycle traffic year-round.
Safety improvements to the Rt 71 over Shark River Drawbridge Included a bicycle safe grid on the draw span which allows bicyclists to cross without the need to dismount.
NJDOT was able to improve traffic flow at the Fifth Avenue intersection with the road diet project. Previously, two southbound lanes crossing the drawbridge on Route 71 were a source of traffic backups with left turning vehicles occupying the left lane, compounded by an abrupt merge south of Fifth Avenue. The merge that previously existed on Route 71 south of Fifth Avenue in downtown Belmar was eliminated with the road diet project. The road diet configuration retained one through lane southbound and installed a dedicated left turn lane at the Fifth Avenue intersection. Signal timings were changed, and a protected left turn phase added to further improve traffic flow. Careful monitoring of traffic throughout the year, and especially during bridge openings, have shown that the road diet lane configuration greatly improved traffic flow.
The Route 71 Drawbridge Project over Shark River, completed in May 2022, delivered several benefits, including improved traffic flow, reductions in traffic congestion, increased safety and an enhanced cycling experience for users navigating a busy shore community tourism area.
Road Diets are a safety-focused alternative to four-lane, undivided roadways that can help reduce vehicle speeds and free space for alternative transportation modes. Road Diets were a recognized model innovation during the 3rd Round of the Every Day Counts Program (EDC-3) Program.
Additional information about the rationale, design and benefits of advancing this innovative bridge safety and road diet project can be found in the video here and in this NJDOT press release.
FHWA recently released its EDC-7 Summit Summary and Baseline Report that can be found here.

NJDOT, like other State departments of transportation (DOTs), has become increasingly conscious of infrastructure’s environmental burdens and are seeking more environmentally sustainable materials in construction. Recently, we spoke with Kimberly Sharp, Manager, Structural Design, Geotechnical Engineering and Geology, and Mohab Hussein, Project Engineer, Deputy Chief Technical, Geotechnical Engineering about NJDOT’s adoption of Foamed Glass Aggregate which serves an example of the deployment of an innovative, sustainable material.
To make foamed glass aggregate, crushed container glass is collected from recycling companies, finely ground into powder and mixed with a foaming agent, and sent through a kiln and softened. Bubbles form within the softened glass. When it cools, the material cracks and forms lightweight, coarse, foam-like aggregate pieces that can be used in various transportation construction projects.
Q. How did you learn of this material?
Foamed glass aggregate in use on the pilot project at Rt. 7 Wittpenn Bridge, Kearny
Aero Aggregates in Eddystone, Pennsylvania, reached out to the Department in 2018 to provide a technical presentation on foamed glass aggregate. An industry presentation is an established step in NJDOT’s process for exploring new technologies. If we are interested in the product, as we were in foamed glass aggregate, we start a pilot project.
Q. When did NJDOT begin using foam glass aggregate?
Our pilot project was the Rt. 7 Wittpenn Bridge in Kearny, NJ in 2019. Use of this material replaced 32,000 cu.yds. of regular fill and saved almost 28 million bottles from the landfill. We used the material for a crossover from one side of the road to the other. We built it and let the contractor use the area for six weeks with heavy equipment traveling over it. We maintained survey equipment at the site and looked for settlement and any lateral spreading and nothing moved.
Q. What have been the most common uses?
For us at NJDOT, the most common uses have been as fill underneath roadways to raise the profile, behind existing abutments where we were putting in a new backwall and new girders and we wanted to lighten the lateral forces on the backwall, as backfill to the approach to a bridge, to resolve sheeting issues on a project, and as backfill behind a temporary wire wall.
Foamed glass aggregate placed behind an abutment on I-80 over Rockaway River, Denville
We have very soft, compressible soils beneath some of our roadways, and in areas of high tide or frequent flooding, therefore we want to raise the elevation of the roadway. Using heavy, natural fill material beneath the pavement box can lead to pavement that ultimately would ride like a roller coaster due to uneven settling. A less costly approach is to over-excavate the existing soil and place with the foamed glass aggregate. At 22 lbs./cu.ft., the aggregate is buoyant, so regular weight soil is placed over it to weigh it down, and then the pavement box is built on top of the soil. Use of the aggregate lessens the amount of settlement and results in a nice smooth roadway.
Q. Who are suppliers of this material?
Aero Aggregates is the supplier that we work with. They recycle glass from Pennsylvania and from a southern New Jersey recycling center. We appreciate that they are using local materials.
Q. What are the environmental benefits of using this material? What is it replacing?
Foamed glass aggregate is saving millions of bottles from landfills. This material is made of 100 percent recycled material. In addition, the material replaces traditional backfill that would be quarried, and so minimizes depletion of natural resources. It also minimizes use of other material such as rebar, concrete and other foundation elements. In addition, it is lightweight, about half the weight of regular lightweight fill material, and so reduces transportation emissions. There are associated cost savings to its use.
Aggregate being applied behind wire wall on Fish House Road, Kearny
Q. Is there an ongoing assessment process for use of this material, or is it an established process?
We had questions in the beginning. The material was so light that we worried about its durability. The manufacturer provided results from testing and we tested the material in the field. Use of foamed glass aggregate is an established process at NJDOT. The material was first used in Germany in the 1980s, and in Norway in the 1990s to prevent rutting of pavements because it has good insulating qualities. It is useful in cold regions.
Q. Are there limits to the transportation construction applications where this material can be used?
Foamed glass aggregate has its own compaction requirements; it is lightly compacted or graded out with lightweight equipment to avoid crushing of the aggregate. As mentioned above, it requires capping to weigh it down. Pavement design engineers want several inches of regular weight soil between the lightweight aggregate and the pavement box.
Q. What is the state of industry knowledge and acceptance of the use of this material?
It is still early in the process of nationwide adoption. New Jersey is one of the first states to implement use of the material on our projects. We have received calls from many state DOTs asking how we began using it, and about our experience of using it in lieu of other lightweight material, so word is getting around. Aero Aggregates used it in Philadelphia around I-95. The industry is working on starting up new plants. Word is spreading through the contracting community. The first contractor that used it with us liked it so much they eliminated all other lightweight types of materials in the contract bid items. Through word of mouth, other design consultants and Contractors have picked up on use of the material.
Q. Do you have current projects where this is being used and do you anticipate continued use of the material in the future?
View video on YouTube or access it from the NJDOT Platform
Yes, and we have some in design, and we will include foamed glass aggregate in the contract for future projects for consideration.
For future projects, we have not used foamed glass aggregate behind structural walls as yet, although we know it has been used in Philadelphia, and we are considering that application.
The Department is also considering applications related to temporary water storage in flood areas. Our current and past projects are using closed cell foamed glass aggregate, but an open cell aggregate is available. Its porosity might be beneficial in flood mitigation and other resiliency projects.
We really like the product and look forward to expanding its use. We are always looking for new technologies and this is one that will continue to be of great benefit.
Q. What do you consider to be the keys to the successful adoption of the material?
Agency willingness has been the key to successful adoption of this innovative material.
The American Association of State Highway and Transportation Officials (AASHTO) Innovative Initiative (AII) program recognized NJDOT’s Sawcut Vertical Curb as one of seven Focus Technologies in 2022. AASHTO held a webinar on Wednesday, April 12, 2023 during which NJDOT practitioners and contractors offered their first-hand experience with implementing the saw-cutting method on their projects successfully. The innovation was also recognized as the NJ’s Build a Better Mousetrap Winner in 2022 and a video description of the innovation can be found here.
Below is a reprint of the AASHTO Innovation Initiative Page that features the Saw Cut Vertical Curb and can be accessed here.
NJDOT’s Saw Cut Vertical Curb is featured as an AASHTO Innovation Initiative.
The AASHTO Manual for Assessing Safety Hardware (MASH) establishes uniform standards for the installation of roadway safety features, including longitudinal barriers. In accordance with the recent MASH standards, the New Jersey Department of Transportation (NJDOT) has updated the installation requirements for guide rails. Per this new requirement, curbs in front of and along guide rail end terminal treatments should be limited to a maximum 2-inch exposure. The typical exposure of existing curbs is four inches. To make guide rail installation MASH compliant, the conventional practice is to remove existing curbs and replace them with 2-inch curbs. The practice typically requires seven days of field operations for the removal, replacement, and curing of concrete. Not only does this timeframe add to labor costs, but also exposes work crews and motorists to work zone traffic for longer periods of time.
NJDOT has developed an innovative method in which the existing curbs can be saw cut to two inches in lieu of removal and replacement. The existing guide rail can remain in place during saw-cutting, while the construction crew can return at a later time to remove and upgrade the guide rail. The saw-cutting approach requires only two days of labor. The process uses a power-driven vertical curb saw fitted with horizontally-oriented, diamond-edge blades or abrasive wheels that are capable of sawing to the required dimensions without causing uncontrolled cracking. The saw is water-cooled, circular, and has alignment guides. The saw is also capable of immediately collecting the slurry produced from cutting the concrete. Traffic control in work areas requires a moving operation set up that includes channelizer barrels and drums, construction signs based on the Manual on Uniform Traffic Control Devices (MUTCD) and DOT standard details, and a truck with a mounted crash cushion.
NJDOT’s Division of Local Aid & Economic Development continues its efforts to make its project management processes more efficient by implementing electronic plan review. The Division is preparing to implement electronic plan review, a feature that was previously incorporated in the Project Management and Reporting System (PMRS), initially launched in 2021, to establish electronic document management, electronic plan review, and other 21st century project management innovations to make project management more efficient.
Training Sessions in an Innovation Context. The adoption of electronic plan review seeks to accomplish key goals aligned with the Department’s commitment to using technology to enable staff to perform routine tasks more efficiently. Ultimately, the transition to an electronic process will reduce paper consumption and centralize and standardize some project management activities. The shift will allow Local Aid project managers, NJDOT Subject Matter Experts (SMEs) and designers to collaborate efficiently, to enable easy file sharing and to track and manage the comment resolution process.
Local Aid’s objectives to improve program delivery through electronic review is well-aligned with EDC-3’s e-Construction initiative. The online training sessions targeted to NJDOT and Local Public Agency and consultants are being funded, in part, through a State Transportation Innovation Council (STIC) Incentive Funding Grant.
Each year the New Jersey STIC seeks to advance the deployment of innovations through the use of STIC Incentive Funding Grants. Click on NJ STIC Incentive Funding Grants to get more information on the purpose, eligibility and uses of NJ STIC Incentive Funding in recent years.
