| 摘 要： | 针对南京市气候条件和道路交叉口的交通特点，通过分析集料级配对沥青混合料抗车辙性能的重要影响，选择2组具有较好抗车辙性能的集料级配AC-16I调整型和SAC-16A与2种sBs改性沥青共4组沥青混合料进行全面的路用性能试验，对比研究了混合料的水稳定性、高温稳定性、抗剪切性能、抗疲劳性能、低温抗裂性能、抗压强度和劈裂强度，重点评价了材料的高温抗车辙性能，从而提出了最佳的南京市道路交叉口路面上面层沥青混合料组成设计。 |

| Abstract: | According to the climate and transportation characteristics at road intersections in Nanjing, important effects of aggregates gradation on rutting resistance of asphalt mixtures are analyzed. Two sets of aggregate gradations in possession of better rutting resistance named adjusted AC (asphalt concrete) 16I and SAC (stone asphalt concrete) 16A, together with two types of SBS (styrene butadiene styrene) modified asphalt, are selected to constitute four sets of asphalt mixtures. By pavement performance's tests of these asphalt mixtures, water stability, stability in high temperature, cutting resistance, fatigue resistance, cracking resistance in low temperature, unconfined compressive strength and cleavage strength of mixtures are comparatively investigated. In this paper, rutting resistance in high temperature of asphalt mixtures is especially evaluated, and the optimal composition design of pavement's asphalt mixtures at road intersections in Nanjing is put forward, respectively. |
