Abstract

Abstract This paper presents the relationship between rutting and aggregate gradation of asphalt concrete using a wheel tracking device at 60°C, with 30,000 cycles in air. The experiment was carried out on hot mix asphalt samples using three aggregate gradations which included maximum aggregate sizes of 9.5 mm, 12.5 mm and 19 mm. The result of the experiment showed that the maximum aggregate size has a great influence on the rutting of asphalt concrete.
