Optimization of Marshall stability and self-healing performance of asphalt mixtures using response surface technology
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.
