英文: Based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck,high-temperature rutting test,low-temperature bending test and controlled stress flexural fatigue test
中文: 在分析钢桥面铺装层主要病害和特殊工作环境的前提下,分别采用高温车辙试验、低温小梁弯曲试验和控制应力小梁弯拉疲劳试验,研究了不同环氧树脂掺量下的环氧树脂改性沥青混合料的高温稳定性、低温抗裂性和抗疲劳性能.试验结果表明:环氧树脂对这3个方面都有很大的改进效果,但改性效果和树脂的添加量并不是一个无限递增的关系,当添加量超过一定数值以后,改性的效果将趋于平稳.最后就高温、低温、疲劳3个方面分别提出环氧树脂添加量为20﹪,30﹪,30﹪的建议值.
