Study Finds Waste Cooking Oil Can Enhance Recycled Asphalt for Road Construction
Laboratory research from the University of Missouri and Sharif University of Technology found that waste cooking oil can soften aged asphalt binder, enabling the use of 60 to 100 percent recycled pavement in new asphalt mixtures. This approach addresses the stiffness of reclaimed asphalt pavement (RAP), which can cause cracking and handling issues. While the oil amount is critical to performance, using waste cooking oil could reduce demand for new materials and support sustainable road construction amid rising raw material costs.
