Road testing: Research team studies potholes in quest for better asphalt sustainability

A research team at Missouri University of Science and Technology is examining asphalt binders, the polymeric materials that hold aggregates together in road construction. Because road surfaces are constantly exposed to sunlight, fluctuating weather and the stresses of daily traffic, these binders can degrade over time, leading to cracks, potholes and reduced lifespan. The team’s work focuses on characterising how different binder formulations perform under simulated environmental conditions and on developing reliable laboratory tests that mirror real‑world wear. By understanding the mechanisms of binder breakdown, the researchers aim to recommend formulations or additives that improve durability and reduce maintenance costs for Missouri’s highway network. The study comes amid broader concerns about infrastructure aging and the need for sustainable, long‑lasting road materials. Results are expected to inform state transportation agencies and could shape future specifications for asphalt mixtures used across the region.
