Strengthening America’s Roadways with Durable Climate Smart Materials

Safe, reliable, and long-lasting roads are essential to a strong national infrastructure system. Pavements designed to improve water drainage help reduce crashes during heavy rain, but they often wear out too quickly, leading to higher maintenance costs and frequent repairs.

This research supports efforts to modernize the United States infrastructure by developing a more durable and climate-smart road surface using recycled rubber and natural, domestically sourced materials. The study evaluates innovative rubber additives enhanced with bio-based treatments and wood-derived biochar, a material made from renewable resources that can improve pavement performance while reducing environmental impacts.

The project examines how these materials improve pavement durability, maintain drainage performance, and limit the release of harmful substances while also assessing their potential to lower the overall carbon footprint of road construction. By extending pavement life and making better use of recycled and renewable materials, this research aligns with national goals to deliver cost-effective, resilient infrastructure that supports economic growth, environmental responsibility, and safer transportation for American communities.
