Research of Fractal Theory to AC-20 Asphalt Mixture Gradation
AC-20 is a widely used in Expressway Close-Graded asphalt mixtures. Based on fractal theory, the fractal dimension range is defined by Marshall Test result analysis of gradation fractal dimension and the Marshall Test parameters. According to the gradation curve of fractal dimension and the degree of fitting, selection of Target Proportioning Design of asphalt mixture, gradation design, optimization test method for reducing test volume has certain guiding role.
