| 摘 要： | 结合青藏高原多年冻土地区年平均气温低、温差大等气候特点,研究AC-13与AC-16级配的SBR改性沥青混合料在不同温度、不同油石比下的劈裂性能,研究表明,AC-16与AC-13级配相比,在低温下,其混合料强度及弯拉应变相对都较大,在多年冻土地区有更好的适用性。

| Abstract: | The effects of the temperature and the asphalt-aggregate ration on splitting characteristics of AC-13 grading and AC-16 grading asphalt mixtures were investigated in the laboratory combining with the climate feature of low annual mean temperature and large temperature difference in Qinghai-Tibet Plateau.The results show that the splitting strength and stiffness of AC-16 grading was larger than AC-13 grading,and when temperature is lower,it is more significant advantage. |
