Undergraduate Research: Alexis Light and Asphalt Performance

University of Arkansas Undergraduate Research Symposium Poster Presentation

Author: Alexis Light | Major: Civil Engineering | Semester: Spring 2025

During my time as an undergraduate student, I conducted my honors research on the statistical analysis of factors influencing the rutting and cracking of asphalt pavement. This work was done under the guidance of Dr. Braham in the asphalt research lab. The research aimed to evaluate how various mix design variables impact the performance and durability of asphalt pavements. By using statistical methods to analyze rutting and cracking data, I sought to contribute to the ongoing effort to improve pavement longevity, which has real-world applications in transportation infrastructure, maintenance planning, and sustainability. My research helps engineers and decision-makers identify the most significant contributors to pavement failure, ultimately leading to better road designs and reducing costs for taxpayers.

I chose this research topic after spending my junior year working in Dr. Braham’s asphalt research lab, where I assisted with various experiments related to pavement materials. My exposure to the ongoing work in the lab helped me recognize the critical importance of pavement performance in everyday life – from road safety to economic efficiency. I was particularly intrigued by how much engineering effort goes into something most people take for granted, like the surface of a road. When the time came to begin my honors research, Dr. Braham and I discussed several possible projects, and we settled on a topic that combined his lab’s ongoing work with my interest in data analysis.

Working on this research deepened my understanding of both the technical and analytical aspects of civil engineering. I learned how different mix design variables could influence the performance of asphalt mixtures over time. On a personal level, I discovered how important persistence and critical thinking are when conducting research. I had to learn how to review large data sets, design appropriate statistical models, and interpret the results in a meaningful way. This project also helped me grow more confident in my ability to manage independent work, adapt to setbacks, and communicate technical information clearly.

One of the biggest challenges I faced was dealing with inconsistent data. Because my analysis relied on data gathered from a range of previous lab experiments, I had to spend significant time cleaning and organizing it before I could even begin the statistical analysis. To overcome this issue, I consulted with Dr. Braham and his graduate students regularly. This experience taught me that problem-solving in research often involves seeking out the knowledge of others.

Dr. Braham played a crucial role throughout the entire research process. He helped me refine my research question, provided access to relevant data, and gave valuable feedback on my methodology and results. His mentorship was instrumental in helping me stay focused and motivated, especially during the more challenging phases of the project. In addition to Dr. Braham, other graduate students in the lab were generous with their time and advice, helping me understand the experimental background of some of the data and offering insights from their own research experiences.

As part of the honors program, I had the opportunity to present my findings at the university’s undergraduate research poster symposium. This was an important milestone for me, as it gave me the chance to communicate my research to a broader audience and receive feedback. While I didn’t have the opportunity to travel, this local conference experience helped me develop my public speaking and presentation skills, which I know will be valuable in my future career.

Looking ahead, I will be working for McClelland Consulting Engineers here in Fayetteville, as a project designer. This role will allow me to apply the skills and knowledge I gained during my research in a practical, real-world setting. I’m excited to contribute to infrastructure projects that directly impact the local community, especially in areas related to pavement design and performance. My experience with data analysis and research methodology has prepared me well for the challenges of this position. I look forward to continuing to grow as an engineer while helping design and implement solutions that improve transportation systems in my region.

This research not only enriched my academic experience but also helped me to see how engineering, data, and public service interact. I encourage other students to seek out research opportunities that align with their interests and to take advantage of the mentorship and resources available to them. The skills and confidence I gained through this project will stay with me long after graduation.
