Corrosion Resistance of Using Very High Strength Steel Reinforcing Bars in Reinforced Concrete Beams– An Experimental and Analytical Approach
Project Description: Advancements in manufacturing methods and the growing demand for high-strength materials in reinforced concrete have led to the development of steel reinforcing bars with strengths exceeding 100 ksi. These ultra-high-strength bars hold significant promise for bridge construction...
View projectFeasibility of Engineered Cementitious Composites (ECC) as Joint Material for Accelerated Bridge Construction (ABC)
Project Description: Advancements in manufacturing methods and the growing demand for high-strength materials in reinforced concrete have led to the development of steel reinforcing bars with strengths exceeding 100 ksi. These ultra-high-strength bars hold significant promise for bridge construction...
View projectEffect of Supplementary Cementitious Materials (SCMs) and waste products on Critical Chloride Threshold, CT, of Concrete
Project Description: Chloride-induced corrosion of reinforcing steel is one of the most significant durability challenges facing concrete infrastructure, especially for bridges, pavements, and marine or deicing-salt exposed structures. A critical parameter controlling corrosion initiation is the cri...
View projectUnraveling the Causes of Fatal Crashes in the U.S.: A Machine Learning Approach to Safer Roads
Project Description: This project investigates the underlying causes of fatal traffic crashes in the United States using advanced machine learning (ML) techniques to enhance road safety. Each year, traffic crashes claim over 42,000 lives nationwide, inflicting significant social, economic, and healt...
View projectAn Initial Step Towards the Development of Predictive Tools to Reduce Particulate Matter from Transportation
Outputs: Successful implementation of this project will create a base modelling framework (in-silico) tool that allows optimization of exhaust systems to reduce disruptive particulate matter. Outcomes/Impacts: Availability of a reliable optimization tool allows for efficient design of various compon...
View projectThermal Treatment Method to Remediate Hydrocarbon-Contaminated Soils
Project Description: Bioremediation, a promising technology, utilizes microbes to break down, transform, and ultimately eliminate specific contaminants such as petroleum hydrocarbons from contaminated soil. This process can be carried out in-situ, directly within the affected region. However, in-sit...
View projectDevelop an Agent-based Modeling Tool to Promote Electrical Vehicle (EV) Deployment and Reduce Lung Cancer Risks
Project Description: The goal of this project is to develop a modeling tool capable of simulating Electrical Vehicle (EV) infrastructure design and user adoption scenarios to facilitate the planning and design of EV infrastructure systems and reduce transportation-related lung cancer risks. Outputs:...
View projectTransport and Mitigation of Tire and Road Wear Microparticles in Stormwater Runoff from Highways
Project Description: The overall goal of this project is to identify transport and mitigation of tire and road wear microparticles in stormwater runoff from highways. Expulsion of microplastics (MP), metals, and other organic contaminants occurs in heavy traffic areas. Microplastic (size range...
View projectRemediation of Oil Products Spillage During Transportation
Project Description: This proposal aims to mitigate the oil spill from the road and water surface using commercial and sustainable dispersants. Frequent spillage of crude oils and refined products during transportation devastates the transportation lines, sewages, and surface waters, which can have ...
View projectA Sustainable Snow-Free Pavement to Mitigate the Negative Effect of Road Salts on Soil and Water
Project Description: Extreme weather in winter, characterized by prolonged and severe conditions, is anticipated soon due to climate change. Consequently, the utilization of deicing chemicals such as salts (including Chloride-based, Formate-based, and Acetate solutions) is inevitable. These chemical...
