Low Temperature Crack Resistance of Recycled Asphalt Mixture with Waste Frying Oil Based on Semi-circular Bending Test
Using AC-20 asphalt mixture (Nominal maximum size 19 mm), the semi-circular bending test of recycled asphalt mixture with different amounts of waste frying oils rejuvenators, were conducted and compared with the virgin asphalt mixture. The test results show that the fracture energy of recycled asphalt mixture increased significantly when a waste frying oil rejuvenator was added. When the RAP (reclaimed asphalt pavement) contents were between 30% and 40%, and the rejuvenator contents were between 10.5% and 12.5%, the fracture energy of recycled asphalt mixture can be restored to 62%–72% of that of the virgin asphalt mixture. Therefore, it demonstrated that the waste frying oil rejuvenator was able to effectively improve the low-temperature crack resistance of the recycled asphalt mixtures.
