Abstract

In this study, an attempt was made to estimate the internal structure characters of HMA (Hot Mix Asphalt). This was done by studying the aggregate orientation, aggregate distribution and internal parameters: φ and C. Four gradations and two types of compaction: vibratory compactor and superpave gyratory compaction (SGC) were analyzed. The results indicate that aggregates compacted using SGC were found to be a more horizontal and uniform distribution but with a larger space between coarse particles (>2.36mm) and smaller C compared with samples compacted using a vibratory compactor. For coarse gradation, the coarse particles were closer and decreased the content of the 2.36mm aggregate and can help the coarse aggregates be compacted more tightly.
