摘要
以矿料主骨料空隙体积填充法、谢伦堡析漏和肯塔堡飞散试验设计出三种不同基体空隙率下的半柔性路面材料,通过马歇尔试验、车辙试验、冻融劈裂、小梁弯曲、疲劳等室内试验评价其综合路用性能。结果表明,半柔性路面材料具有优良的高温稳定性、水稳定性、较强的抗疲劳能力,其低温抗裂能力则稍显不足。
In this paper,performance on Semi-flexible pavement under three different porosity of basic asphalt mixture was designed by the method of Coarse aggregate voids-filling method、experiment of evolution leakage and experiment of scattering.Comprehensive road performance was evaluated through the Marshal test、rutting test、fatigue test and so on.Results show that semi-flexible pavement materials is good at rutting resistance、water susceptibility and fatigue resistance performance.But it’s crack resist-ance performance is not so good.
