Abstract: The aggregate skeleton composition of the stone mastic asphalt with the nominal maximum aggregate size of 13.2 mm (SMA-13) and its contact properties were studied using a three-dimensional discrete element method. A user-writing program was coded with FISH language to extract the contact forces in different sized aggregates (> 2.36 mm). The roles of different sized aggregates and the contact properties between these aggregates were investigated based on the statistical analysis of large amount of data. The results of the study show that aggregates with sizes of 13.2 mm, 9.5 mm and 4.75 mm form the aggregate skeleton of SMA-13, while 2.36 mm aggregates mainly fill the voids of the skeleton. Furthermore, aggregates of sizes 9.5 mm and 4.75 mm are the main body of the skeleton, which bear nearly 60% of the vehicle load on asphalt pavement.

Key words: road engineering, asphalt mixtures, aggregate skeleton, discrete element method, contact force
