摘　　要：采用级配分形理论对AC-13型沥青混合料的级配分维特征进行了研究,并根据水稳定性试验、高温稳定性试验相关结果,探讨级配分维特征与混合料路用性能之间的相关性。结果表明:随着级配的逐渐变粗,AC-13型沥青混合料分维值逐渐减小,可以用分形维数表征其级配状况。同时分形维数和混合料的水稳定性和高温稳定性等有一定的相关性。This paper using the fractal theory to study the gradation fractal dimension characteristics of AC-13-Graded asphalt mixture.According to the result of water stability test,high temperature stability test,Studying of the correlation between fractal characteristics of gradation and mixture performance.The results show that： with the gradation became thick,AC-13-Graded asphalt mixture fractal dimension is gradually diminishing.The value of fractal dimension can be used to describe its graded status.At the same time,there were certain correlation between the fractal dimension and the mixture water stability and high-temperature stability.
