Optimizing asphalt mixtures to be heated by microwave
To heat the asphalt mixture specimens, a microwave oven was used with an output of 1200W and a 230V, 50 Hz power supply. The oven can produce microwaves of up to 700W with a frequency of 2.45 GHz. However, in this research a medium power of 350W was used. The asphalt mixture specimens were cut into two semi-cylindrical halves; then, Latest research is focused on predicting the fatigue behavior of asphalt mixtures through cost-effective and simple test methods on asphalt mastic level (asphalt binder + mineral fines). There are numerous fatigue test methods for asphalt binders and mastic using the dynamic shear rheometer (DSR). However, up to now, the results of the Comparing different fatigue test methods at asphalt mastic level
