Tack Coat Effectiveness Study.

In the last twenty years, I have personally driven over five hundred thousand miles. In that time I have seen many new pavement projects constructed in many different areas. There is one thing that I have personally witnessed on many occasions when those construction projects fail prematurely. Areas where Tack coat should have been used has failed. Some examples are the following. Within two to three years after construction,... more »

The failure of pavements prior to their design life expectancy is a major cause of the increase in annual budgets. It adds more projects to the list of needed construction, helping to dilute the funds available in each budget cycle. Increasing the life expectancy of our roads will allow for those funds to be directed to many places that are in need, but suffer from lack of funding.

Multi-Hazard Design of Highway Bridges

Civil infrastructure is vital to economic development and critical to response and recovery after extreme events. However, they are also quite vulnerable to natural and man-made hazards such as flooding, earthquakes, storm surge, fire and terrorist threats; especially highway bridges. Therefore, there is a need to move toward multi-hazard deign of bridges.

Multi-hazard approach to design of structures will require emphasis... more »

Corrosion Study

With most of the State's infrastructure in need of maintenance and repair, a main cause particularly on steel structures is corrosion. Corrosion which acts in several different forms results in section loss, which reduces capacity of the affected member. To better service the transportation industry, samples should be taken from bridges near or at the end of its useful service life and compare its as-inspected measurements... more »

Why is this a priority and what are the benefits for the State/County/City?

This is a priority as many bridges within the state are near the end of their service life currently. This study if implemented now can gather critical information to better understand effects of corrosion at the end of a bridge's service life, and help develop models which could be used to predict how steel will respond given a certain environment. This information would allow designers to add these considerations into future bridge designs.

Portable Laser Ablation Sampling Device

During my time in Materials inspection and testing with NJDOT, one thing hampered our ability to ensure the adherence to material specifications. That was the ability to track the samples obtained and definitively connect them to what went into structures and roadways. The most accurate way was to cut samples from what was delivered to the site. However, this caused a number of issues between the Resident Engineer and... more »

The quality of the materials going into roads and bridges is the chief indicator of the lifespan and overall strength of what was built. Current sampling methods can cause contractors to purchase extra materials, which increases costs. Any onsite sampling can cause a delay in construction. Being able to adequately test materials without creating these issues is a benefit to all involved.

Development of Low-Embodied Carbon Concrete Mixtures for NJDOT

The State of New Jersey has independently joined the Paris Climate Accords and uphold the goals of the Paris Climate Agreement. Per this agreement, an overall carbon reduction of 14% needs to be achieved within the United States. Concrete is responsible for around 8% of the world's CO2 production, mainly due to the production of portland cement. Therefore, finding methods to reduce the carbon footprint of concrete can... more »

Meeting carbon reduction targets is a broad goal set by the State of NJ, in which all agencies are expected to participate. This work will support NJDOT in choosing sustainable, lower-embodied carbon concrete solutions that do not sacrifice concrete quality or cost. The benefit of this work will be realized in better concrete durability, lower life-cycle cost, and more sustainable concrete materials that can be used in a wide variety of projects across the state. It is anticipated that the final guidance documents and suggested changes to NJDOT specifications will result in more resilient transportation infrastructure that is being built to maximize performance while minimizing environmental impacts. Implementation of this work will make NJDOT a leader in sustainable concrete construction practices, supporting statewide and regional goals for carbon reduction.

Pulaski Skyway Rocker Bent Rehabilitation

As a part of the ongoing Pulaski Skyway Rehabilitation project, one of the tasks include the rehabilitation of a traditional railroad style truss expansion device similar in function to the more commonly known pin and hanger mechanism, referred to in the original plans as 'Rocker Bents'. However, a key difference being that these members act in compression as opposed to tension. The original detail proved unsustainable,... more »

Extend Service Life of Concrete Bridge Decks with Internal Curing

Curing is a critical step in concrete pavement construction. Due to the large surface area to be covered, external curing methods normally do not provide concrete with necessary moisture conditions for long-term hydration. Insufficient curing often causes internal cracks or shrinkage cracks on the surface of the pavement. These early-age cracks not only hurt the strength, but also increase the permeability so that chlorides... more »

Why is this a priority and what are the benefits for the State/County/City?

Internal curing can minimize concrete cracking at very early age. Early age cracking, most are due to shrinkage caused by lacking of curing, will hurt the long-term performance and the durability of concrete. It may cause severe corrosion of rebars, as chlorides and other aggresive ions from deicing chemicals can easily penetrate deep into the concrete layer. Internal curing can also lead to a denser structure of concrete, so that the material is better performed when freeze-thaw cycles happen.

Considering the geographic location of New Jersey and the dense polulation, the pavement maintenance cost is huge each year. Therefore, improve the quality of pavement can not only save efforts and costs of repairing, but also making it a safer place to commute for NJ residents.
