In 2005, North Carolina researchers put recycled nylon carpet fibres into asphalt; lab tests gave the mix 85% higher fracture energy, helping fight cracks

Innovative research from North Carolina State University reveals that incorporating nylon carpet fibers into asphalt significantly enhances its crack resistance. Testing demonstrated an impressive 85% increase in fracture energy. With carpet waste often posing landfill challenges, this sustainable approach could fortify road surfaces, potentially minimizing repairs and maintenance costs. However, substantial field trials are necessary to validate these promising laboratory results.
