【摘要】 在矿料、沥青材料试验研究的基础上开展沥青混合料组成设计试验研究,提出了供工程使用的高性能沥青混合料级配组成设计建议范围.高性能沥青混合料路用性能检验结果表明,其高温稳定性高于国内常用的AC-I沥青混合料.此外还用高应力比模拟重载交通研究了高性能沥青混合料的疲劳性能,发现重载情况下的疲劳规律与一般荷载下的疲劳规律一致.试验路的观测与分析结果表明达到了预期的目标.更多还原

【Abstract】 Based on tests of aggregates and asphalt materials,study on the gradation of asphalt mixture of high performance was performed and recommends to gradation were given.The high temperature properties of asphalt mixture of high performance were better than that of traditional AC-I.In addition the study on fatigue properties found that the fatigue law of high stress ration which stimulated heavy loading was similar to that of common stress ration.The observation and analyses of test roads also supported the results of study.更多还原
