ln this paper, two sets of aggregate gradation (AC-13C and SMA-13)were se- lected to use together with two types of asphalt (road bitumen and modified asphalt) accord- ing to the climate and transportation characteristics at road intersection in Nanjing. The four sets of asphalt mixtures were evaluated by pavement performance tests, included water sta- bility, stability in high temperature, cracking-resistance in low temperature, unconfined compressive strength and cleavage strength. By comparative analysis, the optimal composi- tion design of asphalt mixture pavement at road intersection in Nanjing was put forward.
