Comparison of Vegetation Types for Prevention of Erosion and Shallow Slope Failure Along Roadways 

Asima, Homayra (2022-08-03)  ETD File Embargoed
Shallow slope failures due to erosion are common occurrences along roadways in Alabama due to the prevalence of high intensity rainfall in the region. The use of vegetative covers is a reasonable solution to stabilize newly ...

A ‘Concentrate-&-Degrade’ Technique for Cost Effective Adsorption and Degradation of Per-and Polyfluoroalkyl Substances in Water 

ZHU, YANGMO (2022-07-25)  ETD File Embargoed
The overarching goal of this research is to develop and test a new class of carbon-photocatalyst composites for enhanced adsorption and destruction of per- and polyfluoroalkyl substances (PFAS) in water and field water. ...

A ‘Concentrate-&-Degrade’ Technology for Cost-Effective Adsorption and Photodegradation of Per-and Polyfluoroalkyl Substances in Municipal Landfill Leachate 

Zulfeqar, Najibullah (2022-11-29)  ETD File Embargoed
Per-and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been widely used in industry and daily consumer products. Due to the wide application of these products and their recalcitrant nature ...

A Critical Opportunity: Lead in Drinking Water at Child Care Facilities 

Stanbrough, Elizabeth (2021-01-19)
There is no safe level of lead exposure. As exposure from point sources like lead paint have been reduced through legislation, non-point sources such as drinking water have become a greater proportional source of total ...

Design and Performance of Open-Graded Friction Course Mixtures Containing Epoxy Asphalt 

Anand, Anurag (2021-11-30)  ETD File Embargoed
Open-Graded Friction Course (OGFC) is a type of pavement primarily composed of coarse aggregates and high asphalt content. Higher permeability, better friction resistance, improved visibility, reduced pavement noise, and ...

Developing a Tool for the Design and Cost Optimization of Permeable Pavements in the Planning Stage of Stormwater Management 

Biessan, Don Guy Virgile Vianney (2021-07-12)
Stormwater runoff, when not managed properly, can represent a threat to the environment especially in today’s urban setting. For small pavement applications such as parking lots, conventional pavements and best management ...

Development and Adjustment of MDOT’s Pavement Condition Ratings (PCRs) 

Brenes-Calderon, Anthony (2022-11-30)
Pavement condition assessment is a fundamental activity of every pavement management system (PMS). It determines the overall road network condition, as well as possible maintenance and rehabilitation activities (M&R) for ...

Development and Application of Composite Beam Theory on FRP Reinforced Concrete Flexural Members
