The Water Stability Prediction Model Of Gac-20 Modified Asphalt Mixture

GAC-20 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 GAC-20 asphalt mixture can be predicted according to the gradation designed. This can reduce the test workload and offer the reference for engineering design.
