Abstract: To ensure a long lasting pavement, and safe and excellent service, a new technology in asphalt mixtures, which includes self-healing property, was developed. The binder was modified using magnetic particles, homogeneously distributed on its bituminous mixture that can be activated using microwave radiation under various magnetic particle content (0%, 49.6% and 99.2%), varying bitumen content (8%, 10% and 12%), and different concentrations of coconut fiber filler (0.5%, 0.75% and 1%). The mechanical behavior based on Marshall Stability Test (ASTM D 1559) and air voids were evaluated using response surface modeling; stability and %air voids of the binder as responses. The self-healing property of the binder was evaluated after subjecting it to microwave heating. A quadratic response model was obtained for both stability test and %air voids. Increasing the magnetic particle up to 49.60% has increased the stability of the binder while using 0.75% filler content resulted to highest %air voids. Accordingly, asphalt samples with 99.20% magnetic content presented the fastest heating rate after subjecting it to microwave heating for 120 seconds which denotes best self-healing performance. The optimum design was achieved at 65.98% magnetic content, 0.95% coconut fiber filler content, and 12% bitumen content.
