摘要/Abstract

摘要： 针对玄武岩纤维在沥青混合料中的空间分布状态,利用MATLAB、AutoCAD和ABAQUS等软件,建立了玄武岩纤维在沥青混合料内的分布模型,研究了不同纤维空间分布状态对沥青混合料性能的影响。基于空间随机分布模型,分析了不同纤维掺量和长径比对沥青混合料弯拉性能的影响,研究结果表明:随着纤维掺量和纤维长径比的增大,沥青混合料层底最大弯拉应力呈减小趋势,即沥青混合料抗弯拉性能越好,考虑经济性和实际施工情况,得到0.3%掺量和纤维长径比为35(纤维长度为6 mm)时,纤维加筋效果最佳。研究成果对玄武岩纤维在沥青混合料中合理掺量和长径比选择提供参考。

Abstract: Aiming at the spatial distribution of basalt fibers in asphalt mixtures, the distribution model of basalt fibers in asphalt mixtures was established by using MATLAB, AutoCAD and ABAQUS. The effects of different spatial distribution of basalt fibers on the performance of asphalt mixtures were studied. Based on the spatial random distribution model, the effects of different fiber content and aspect ratio on the flexural-tensile properties of asphalt mixtures were analyzed. The results show that with the increase of fiber content and fiber aspect ratio, the maximum flexural stress of asphalt mixture layer bottom tends to decrease, that is, the better flexural-tensile performance of asphalt mixture. Considering the economy and actual construction conditions, the best effect of fiber reinforcement is obtained when fiber content is 0.3% and fiber aspect ratio is 35 (fiber length is 6 mm). The research results can provide a reference for the selection of reasonable basalt fiber content and aspect ratio in asphalt mixture.
