    Abstract

    A laboratory investigation was performed in which the influence on resistance to plastic deformation as demonstrated when rounded, smooth, sand-sized aggregate particles were replaced by rough, angular, porous particles while other aggregates and the total gradation remain the unchanged. Five asphalt concrete mixtures with varying amounts of these aggregates were tested. Resulting data were used to (1) evaluate the ability of certain test procedures to differentiate rutting potential of the mixtures, (2) develop a new rutting model for predicting pavement performance which incorporates aggregate characteristics, (3) examine fractal dimension analysis as a method of quantifying aggregate angularity and surface texture, and (4) demonstrate that octahedral shear stress theory can properly differentiate the rutting potential of asphalt concrete mixes.
