SMA-16 modified asphalt mixture are designed by referencing the orthogonal design method, the freeze-thaw cycle rutting test are carried out, the related model of the fractal dimension and the water stability evaluation index including freeze-thaw cycle dynamic stability ratio is established by using fractal theory. The water stability of SMA-16 asphalt mixture can be predicted according to the gradation...
Correlation models of fractal volume parameters and fractal dimension of SMA-16 modified asphalt mixture are established. The volume parameters of SMA-16 modified asphalt mixture can be predicted by the known fractal dimension, which is advantageous to the grading test, so as to determine the structure type of asphalt mixture. Thereby the workload can be reduced and the design efficiency can be improved.
