| 摘 要： | 为把握沥青混合料抗车辙性能实质,优化设计效果,利用汉堡车辙仪测试了不同混合料的高温稳定性,对其进行了旋转压实和间接拉伸试验,并对试验结果进行了回归分析.试验结果显示级配对混合料高温性能有重要影响,且根据走向确定矿料级配具有较强的局限性;通过改变油石比、测试温度和加载速率等,建议间接拉伸试验的测试条件为温度40℃,加载速...

| Abstract: | In order to know the essence of rutting performance of asphalt mixture well and make the design effort better,the high-temperature stability of mixtures was analyzed with Hamburg rut-meter,SGC and IDT test were performed,and the regression analysis for the test results was performed.It is proved that aggregate gradation has great influence on high-temperature performance of asphalt mixture,and the gradation is rather limited according to the trend.After comparing the influence of asphalt aggregate ratio,tem... |
