Prediction model for low-temperature performance of AC-13 cold patch asphalt mixture

Abstract A set of AC-13 cold patch asphalt mixtures (No. 1-9) was designed using the orthogonal design method. The performance parameters such as flexural failure strain εB and flexural strength R B obtained from the experiment under low-temperature were linearly fitted with the fractal dimension and a correlation model between the low-temperature performance evaluation in the x. The fractal dimension of the AC-13 cold mix mixture was established.
