Abstract :
AC-13 is selected as typical grading, and the asphalt mixture water stability test research is conducted. The influence of mineral aggregate gradation to AC-13 asphalt mixture water stability is analyzed; and the fractal theory is used to analyze the freezing and thawing split test result, then the AC-13 grading fractal dimension number value scope with good water stability is obtained. Based on those conclusions the suggestion on how to choose the surface layer asphalt mixture mineral aggregate grading in the moist and rainy area is proposed.
