Study on road performance of waste cooking oil regenerated asphalt and recycled asphalt mixture
In order to recover the properties of aged asphalt and promote the high-quality recycling of RAP,the aged as-phalt was regenerated by using waste cooking oil to supplement the light component of aged asphalt,the influence of waste cooking oil on the basic road performance of regenerated asphalt and recycled asphalt mixture were systematically studied,and the suitable amount of waste cooking oil is determined.The test results show that the penetration and ductility of the regenerated asphalt increased with the increase of the waste cooking oil content,while the softening point and viscosity de-creased with the increase of the waste cooking oil content.The optimum amount of waste cooking oil is about 10%.The road performance of waste cooking oil recycled asphalt mixture meets the requirements of the code when the content of RAP is less than 50%.
