Abstract:

为分析不同沥青混合料的抗车辙性能，本文针对沥青混合料的空间结构特征，基于车辙试验结果，从体积指标下手。借助计算机辅助软件得出不同沥青混合料类型的VMA值、VCAratio值与动稳定度DS、60 min车辙深度之间的函数变化曲线。分析其函数变化曲线变化趋势，评价不同沥青混合料的抗车辙性能，并得出沥青混合料体积指标与抗车辙性能之间的连续变化规律，为后续相关研究提供数据支持。
In order to analyze the rutting resistance performance of different asphalt mixtures, this paper focuses on the spatial structure characteristics of asphalt mixture and starts from the volume in-dex basing on the results of the rutting test. The computer-aided software is used to obtain the function curve between the VMA value, the VCAratio value and the dynamic stability DS and the 60 minutes rut depth of different asphalt mixture types. The trend of the change of the function curve was analyzed to evaluate the rutting resistance performance of different asphalt mixtures. And the continuous change law between the volume index of asphalt mixture and the rutting resistance performance is obtained, which provides the data support for subsequent related researches.
