The Arkansas Department of Transportation's Transportation Research Committee conference and equipment expo was recently held in Hot Springs. This annual event serves as a vital platform for presenting the latest advancements in transportation research, technology, and equipment. Civil engineering graduate students Shuyah Ouoba, Tanner Turben, and Amarjeet Tiwari, along with faculty members Ernie Heymsfield, Suman Mitra, Sarah Hernandez, Stacy Williams, Cameron Murrayand Michelle Barry, were among those who presented their research.

The conference featured presentations from industry experts who discussed innovative research projects and future trends in transportation infrastructure. Attendees had the opportunity to participate in workshops and panel discussions covering a variety of topics, including safety improvements, construction techniques, and sustainable practices.

Doctoral student Shuyah Ouoba provided an update on Project TRC2203, which focuses on low shrinkage concrete mixtures for Arkansas. "Transverse cracking affects the durability of concrete bridge decks and primarily results from drying shrinkage. Basic mixtures were prepared using the current Department of Transportation specified mixture proportions and different coarse aggregate types typically used in the state. These mixes were then optimized by adjusting the coarse aggregate gradation and reducing the cement content by 5.9% and 15.4%. Substitution with 20% and 30% Class C fly ash was also made. The fresh and hardened concrete properties, such as the drying shrinkage and electrical bulk resistivity, are tested and compared to evaluate any potential improvements."

Faculty members presented their research projects on several topics:

In addition to the research update sessions, research project posters were displayed throughout the conference, providing more information and updates about the ongoing projects in Arkansas. Master's student Tanner Turben presented a research poster titled "Impact of Equipment Type on Particle Size Measurement of Civil Engineering Materials."

Faculty members also submitted posters for other projects, including:

These projects aim to help Arkansas Department of Transportation design transportation infrastructure that enhances public safety and longevity, ultimately saving lives and tax dollars in Arkansas. The event also provided students with valuable real-world experience that will benefit their future careers.

The equipment expo showcased the latest tools and machinery used in transportation projects, including demonstrations of new construction equipment, traffic management systems, and other technologies designed to improve efficiency and safety in transportation infrastructure.

This annual event fosters knowledge sharing and collaboration between professionals, as well as between the public and private sectors, to enhance Arkansas'transportation systems.
