CHDT will improve guidance and technical assistance to DOTs and MPOs to minimize negative impacts and disparities from transportation investments on the environment.
Projects
Surface Modification Approaches to Turn Waste Plastics into Beneficial Additive for Concrete (active)
US DOT Priorities: This project directly addresses DOT’s research priority of “Preserving the Environment” by developing novel approaches to turning waste plastics into a beneficial additive for concrete, leading to effective mitigation strategies to address the potential pollution...
View projectAdvancing Sustainable Transportation with Innovative Near-Zero Carbon Emission Cement Derived from 100% Industrial Byproducts (active)
Project Description: The proposed project aims to develop a near-zero carbon emission cement made entirely from 100% industrial by-products. This initiative supports the Department of Transportation's goals by promoting sustainable construction practices that significantly reduce carbon emissi...
View projectInvestigation of Bridge Scour Mitigation with Nature Binding Material: Seaweed (active)
Project Description: Green construction material plays an important role in sustainable development. With the development of construction materials, biopolymers are gradually being used as a soil improvement additive in geotechnical engineering. Seaweed, also known as macroalgae, is a diverse group ...
View projectQuantitative Study of Environmental Condition and PFAS Impacts on Microplastic (MP) Fate and Transport due to Effects on MP Flocculation (active)
Project Description: Microplastics (MPs) are a class of emerging contaminants of concern that result from the degradation products of plastic-based fibers, particles, and films. Transportation related pollution contributes notably to MP pollution in the environment, particularly in urban areas where...
View projectAn Initial Step Towards The Development Of Predictive Tools To Reduce Pollution From Transportation (active)
US DOT Priorities: This project aims at mitigating the particulate pollution from transportation systems towards Preserving the Environment and Climate and Sustainability Outputs: Successful implementation of this project will create a base modelling framework (in-silico) tool that allows optimizati...
View projectDissecting Disparities: How Transportation-Related Air Pollution Influences Childhood Cancer Across Racial/Ethnicity, Socioeconomic, and Geographic Lines in Texas (active)
Project Description: The relationship between environmental exposure and childhood cancer (ages 0-19 years), particularly due to transportation-related air pollution such as benzene and 1,3-butadiene, is increasingly evident and concerning. Despite childhood cancer being relatively rare, it remains ...
View projectEmpowering Sustainability and Equity: Harnessing School Buses for Workforce Transit (active)
Project Description: In addressing the dual challenges of environmental sustainability and transportation equity, the project aims to repurpose school buses for workforce transportation. This strategy emerges against a backdrop where low-income individuals frequently face limited access to efficient...
View projectA Framework To Boost Reactivity And Consistency Of Agricultural Residual Ashes As A Supplementary Cementitious Material (active)
Project Description: Decarbonizing transportation infrastructure is one of the primary goals of the US DOT. This project aims at decarbonizing transportation infrastructure by reducing the cement usage during its construction and maintenance. For this purpose, agricultural residues (corn stover and ...
View projectThermal Treatment Method to Remediate Hydrocarbon-Contaminated Soils (active)
Project Description: Bioremediation, a promising technology, utilizes microbes to break down, transform, and ultimately eliminate specific pollutants such as petroleum hydrocarbons from contaminated soil. This process can be carried out in-situ, directly within the affected environment. However, in-...
View projectInvestigating the Impact of Land Use Disturbance on Streamflow Regime and Sediment Connectivity in Urban Headwater Systems (active)
Project Description: Streamflow regime is defined as the frequency, magnitude, duration, and timing of surface streamflow presence in a stream network. In headwater stream systems—stream reaches that form the start of river networks—streamflow regimes are highly dynamic, helping to maint...
