註釋The importance of aggregate structure on asphalt mixture performance has been well established. Unfortunately, the methods and specifications for current mix design provide little in terms of guidance or criteria to assure that the aggregate gradation selected will result in a favorable aggregate structure that increases mixture resistance to rutting and cracking. Consequently, there is a clear need for mix design guidelines and criteria, particularly as related to the gradation of the coarser aggregate used in the mixture. The main purpose of this research was to develop an approach to analyze and evaluate mixture gradation to determine whether the coarse aggregate will interlock sufficiently to provide necessary resistance to deformation and fracture. The approach would provide the basis for developing mix design guidelines and specifications for improved performance of asphalt mixtures.
