Roads in cold climates and coastal regions face constant threats from harsh weather conditions, leading to rapid deterioration and posing safety risks to motorists. This project aims to strengthen asphalt roads, reducing the need for repairs and lessening their impact on the environment, economy, and society.

Drawing inspiration from mussel-binding proteins, the research team will develop specialized materials to enhance the bond between asphalt binders and aggregates. The team will investigate how these materials function at a molecular level, conduct practical strength tests, and collaborate closely with a road expert to ensure their practical utility. The ultimate objective is to create more durable asphalt, thereby minimizing issues like potholes and cracks. Increasing road resiliency will reduce waste and energy consumption associated with repairs, as well as pollution from asphalt processing. Prolonging the lifespan of roads will also save money and enable funds to be allocated to other essential projects.

The research team hopes that by enhancing road safety and reducing traffic congestion, more durable roads will contribute to improved quality of life for communities, alleviating stress on commuters and travelers.
