　　Crushing and screening RAP is necessary to meet the grading requirements of recycled asphalt mixture design, and old aggregates with severe damage must be screened out.

　　(1) Broken. Generally speaking, RAP recovered by milling does not require crushing or only requires one level of crushing to meet the requirements. However, RAP recovered through traditional methods needs to undergo secondary crushing and screening treatment to minimize the content of large particle aggregates and reduce the impact of differences in recycled materials, in order to obtain a recycled mixture that meets the grading requirements.

　　(2) Screening. Screening can effectively reduce the impact of variability in recycled materials and ensure the accuracy of secondary design. Recycled materials need to be screened in different grades. Japan divides old materials into three grades: 0-5, 5-13, and 13-25mm, while the United States usually uses two grades: 0-13 and 13-19mm. In China, the screening is generally divided into two grades: 0-13 and 13-25mm. Large particle size particles are heated slowly and are not easily covered by asphalt in mixing equipment, so some experts suggest not using screening materials larger than 13mm.
