摘 要: 引入分形理论进行小粒径沥青混合料级配设计,通过对集料破碎规律研究,得到最可能分形维数值。根据分形维数计算得到的集料级配结果,进行了小粒径沥青混合料的目标配合比设计,并对比了设计所得混合料与规范推荐的SMA5,SMA10室内性能差异。 Based on fractal theory, the gradation of small size asphalt mixture is designed. Utmost grading fractal dimension, which is used to design the aggregate gradation, can be calculated based on the aggregate crushing rule. The target proportioning of small size asphalt mixture is achieved, with the contrast evaluation of its laboratory performance with SMA5 and SMA10.
