FRACTALS OF AGGREGATES CORRELATED WITH CREEP IN ASPHALT CONCRETE
The authors conducted laboratory tests to determine the influence of shape and surface texture of coarse aggregates on the deformation characteristics of asphalt concrete mixtures. Fractal dimension analysis was employed to determine shape and surface texture of aggregates. Seven different aggregate blends of similar gradation containing coarse aggregate from 100 percent uncrushed to 100 percent crushed were used to prepare the asphalt concrete mixtures. The material properties measured were Marshall and Hveem stability and creep and permanent deformation. Fractal dimension analysis proved to be a suitable method for characterizing aggregate particle shape and surface texture. A direct correlation was found to exist between permanent deformation of asphalt concrete mixtures and surface texture of coarse aggregate particles used in the mixtures. Therefore, fractal dimension of aggregate particles used to prepare asphalt concrete mixtures is related to rutting and shoving in asphalt pavements.
