Evaluation of mixed mode I/II fracture behavior of asphalt concretes containing polyvinyl alcohol and coconut fibers

Key Points

• Mixed mode fracture behavior is enhanced in asphalt concretes with added polyvinyl alcohol and coconut fibers, showing improved durability.
• Key evidence shows a significant increase in fracture toughness, making these modified asphalts potentially more resilient under stress.
• Observational analysis characterizes mixed mode fracture in asphalt concrete incorporating polyvinyl alcohol and coconut fibers across multiple tests.
• Findings highlight the need for incorporating innovative materials in asphalt mixtures to improve structural integrity and lifespan.
