| 摘 要： | 废旧轮胎堆积造成“黑色污染”已成为世界各国普遍面临的环境问题,为了有效利用废旧轮胎,解决橡胶粉作为改性剂的难点,采用3种不同剂量的废旧橡胶轮胎粉(CR7、CR10、CR13)作为改性剂,研究其对基质沥青AH-70物理特性和动态流变特性的影响,矿料级配采用AC-13型,对这4种沥青混合料进行马歇尔试验、车辙试验、劈裂试验、低温弯曲试验测定,分析橡胶粉掺量对沥青性能的影响。试验结果表明,橡胶粉的加入有效提高了沥青高温性能、水稳定性和低温性能,综合得出,CR10改性沥青混合料比AH-70、CR7和CR13沥青混合料具有更好的路用性能。研究成果为废旧橡胶轮胎用于公路建设的再生利用,提供理论参考和借鉴。
