| 摘 要： | ATB是一种密级配沥青稳定碎石混合料,本文借助分形理论,对其5种不同级配曲线走向沥青混合料的矿料间隙率与矿料级配分形维数的关系进行了研究.结果表明：矿料级配分形维数是一个含有丰富信息的参数,其与沥青混合料的矿料间隙率存在很好的相关性,同时,建立了ATB-25型沥青混合料矿料级配分形维数与沥青混合料矿料间隙率的回归模型.

| Abstract: | ATB is a dense-graded asphalt stabilization macadam base mixture.Using fractal theory in this paper to research relation between aggregate gradations’ fractal dimension and voids in mineral aggregate of 5 different grading curve trend asphalt mixture.It has shown that aggregate gradations’ fractal dimension is an important parameter with rich information content.There is a strong correlation between aggregate gradations’ fractal dimension and voids in mineral aggregate.A regression model for aggregate gradations’ fractal dimension and voids in mineral aggregate of ATB-25 is derived. |
