Small size asphalt mixture that usually refers to asphalt mixture with nominal maximum aggregate size (NMAS) of 4.75 mm and 9.5 mm, is widely used in preventative maintenance program and sidewalk projects. Based on fractal theory, the relationship between passing percentage of aggregate and fractal dimension was founded. Utmost grading fractal dimension, used to design the aggregate gradation, can be calculated based on the aggregate crushing rule. The optimal asphalt content of small size asphalt mixture is achieved through Marshall Design method. Drainage test and Canter test were used to examine the optimal asphalt content. According to the results of aggregate gradation and optimal asphalt content, small size asphalt mixture was obtained. Small size asphalt mixture was tested by the laboratory performance tests including wheel tracking test, skid resistance test and water stability test. Comparing with the performance of SMA5 and SMA10, the small size asphalt mixture designed by fractal theory has a better pavement performance.
