Techniques for Preventing Shrinkage Cracking and Early Corrosion of Concrete Bridge Decks In Reserve

Demand for rapid construction procedures has resulted in the development of concrete mixtures with faster strength gains so that roads and bridges can be opened up quickly. This move has, however, resulted in the formation more drying and plastic shrinkage micro-cracks in concrete bridge decks and pavements. These micro-cracks are fast paths for the ingress of water and aggressive chemicals that can cause corrosion of... more »

How to fix the Portal Bridge and other possible single points of failure? In Reserve

The Portal Bridge, an important commuter rail bridge connecting New Jersey to the hub of New York City, is a vital component of our transportation system. When it gets stuck, commuters get delayed, complaints go up, and satisfaction with NJ TRANSIT services go down. Underfunding has delayed a bridge repair or replacement, and it may be worthwhile to look into ways of funding and creating a repair/replacement for the Portal... more »

Improved Climate Inputs for Pavement Design in New Jersey In Reserve

Environmental conditions have significant effects on performance of both flexible and rigid pavements. In the current AASHTO Pavement ME, an Enhanced Integrated Climatic Model (EICM) uses climatic data to simulate internal pavement temperature, moisture, and freeze-thaw conditions as a function of time. EICM requires historical records of five weather-related parameters reported on an hourly basis: air temperature, precipitation,... more »

Innovative materials for subgrade reinforcement in New Jersey In Reserve

The engineering characteristics of subgrade materials are important to the integrity and serviceability of pavement. The most critical characteristics include load bearing capacity and volumetric change. The subgrade must be able to support loads applied on pavement without excessive deformation, and able to maintain its volumetric structure under severe temperature and groundwater level variations. To enhance the shear... more »

New Jersey has the third-most movable bridges of the 50 states, with an average age of approximately 40 years and more than 50% of these bridges are structurally deficient mainly due to their bridge decks. Moreover, many of these bridges, whether state or locally owned, are subjected to significant amounts of average daily truck traffic (ADTT). Because of their condition and their location on significant commerce routes... more »

Influence of Platooning Trucks on Bridge Strength, Serviceability and Durability In Reserve

Given the significant savings in fuel consumption (due to improved air dynamics) and the relatively simple control schemes required (compared to other autonomous vehicle scenarios) truck platooning is expected to be one of the first applications of autonomous vehicles. Although much work is ongoing in the realm of control schemes, communication protocols, signage, driver training, and policy, little (if any) attention... more »

Plastic Roadways In Reserve

From India and Scotland, to Texas USA, plastic additives are utilized in patching potholes, repairing cracks, and could be mixed with bitumen to create full paved roads. This action could help with a reduction of plastic waste, a decrease of material cost, a stronger durability with roads, and done without causing leeching or harm to the environment.
