摘要: <正>针对南京市城市气候特点和道路交叉口的交通特点,采用AC-13C型、SMA-13两种矿料级配与两种沥青(道路石油沥青和改性沥青),共组成4种沥青混合料进行路用性能试验,研究了沥青混合料的水稳定性、高温稳定性、低温抗裂性、抗压强度和抗拉强度。通过对比分析,得出了适用于南京市道路交叉口路面上面层的沥青混合料组成以SMA-13为好。

Abstract: 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.
