LEAP Connection — November 2025

LEAP Program: University of Arkansas Tour —

Submitted By: Alan Campos, Pavement Recycling Systems

Dr. Andrew Braham, Professor of Civil Engineering at the University of Arkansas (U of A), hosted the LEAP Program for an exclusive tour of the university and its graduate asphalt program. The visit began with a networking session between LEAP professionals and PhD candidates. This exchange allowed industry representatives—including lab managers, emulsion plant managers, and logistics experts—to demonstrate the vast scope of the asphalt industry.

In return, students presented their semester-long group projects, which covered:
• Comparison of Lab-produced Asphalt Emulsions by Measuring Equipment Type
• Comparative Life-Cycle Cost Analysis of Flexible and Rigid Pavements
• Development of New Storage Stability Testing Methods for Asphalt Emulsions
Following these thought-provoking presentations, Dr. Braham led a walking tour of the campus, highlighting the Bell Engineering Center, the stadium, and the university's famous Senior Walk.

The second day began at the Engineering Research Center (ENRC) with technical presentations regarding material particle size, sealant materials for FDR, and prime and tack coat optimization. The itinerary concluded at the new state-of-the-art Grady Harvell Civil Engineering Research Center. This facility featured impressive setups, including vertical 3-D printing and structural stress analysis testing. Attendees also inspected the TREAT Mobile lab and specialized equipment, such as the R.C. chip sealer and slurry spreader which are impressive as they open the door to new constructions techniques and safety.
