摘要:
为了探究再生沥青混合料(RAP)掺量对再生半柔性路面路用性能的影响,以体积法设计基体沥青混合料级配.通过浸水马歇尔试验、冻融劈裂实验、低温劈裂实验及车辙实验,分析评价不同RAP掺量再生半柔性路面路用性能.结果表明:RAP材料的变异特性、RAP掺量变化等因素使不同路用性能呈现不同变化趋势;当RAP掺量较低时,相关路用性能指标表现良好,当RAP掺量过高时,路用性能明显下降,且劈裂抗拉强度比不满足规范要求;RAP掺量对车辙深度、劈裂抗拉强度和残留稳定度影响较大.
Abstract:
In order to investigate the effect of the dosage of recycled asphalt mixture(RAP)on the road performance of recycled semi-flexible pavement, the matrix asphalt mixture gradation was designed by volume method. Through submerged Marshall test, freeze thaw split crack test, the low temperature split test, and temperature rut test, the road performance of different semi-flexible pavements with different RAP dosage were analyzed. The results show that the variation characteristics of RAP materials and the variation of rap content make different trends on road performance. When the RAP content is low, the relevant road performance indicators perform well. When the RAP content is too high, the road performance is significantly reduced, and the tensile strength ratio does not meet the requirements of the specification. The RAP content influences obviously the rutting depth, splitting tensile strength and residual stability have close.
