玄武岩纤维筋网沥青混合料的层间抗剪特性研究
Study on Interlayer Shear Resistance of Asphalt Mixture Reinforced by Basalt Fiber Mesh
摘要
Abstract
To investigate the interlayer shear properties of basalt fiber-reinforced asphalt mixtures,a composite plate shear test method was proposed.The study examined the effects of the diameter and mesh spacing of the basalt fiber reinforcement mesh on the interlayer shear strength and interlayer bond coefficient of the asphalt mixture.The results indicated that both the interlayer shear strength and interlayer bonding coefficient initially increased and then decreased as the diameter and interlayer spacing of the basalt fiber reinforcement mesh increase.Specifically,when the mesh diameter was 6 mm and the mesh spacing was 60 mm×60 mm,the basalt fiber mesh had the most significant positive impact on enhancing the interlayer shear properties.The interlayer shear strength and interlayer bonding coefficient increased by 28％and 78％,respectively,compared to the values without a basalt fiber reinforcement mesh.Conversely,when the diameter of the reinforcement mesh exceeded 8 mm,or when the mesh spacing was either 40 mm×40 mm or 100 mm× 100 mm,the installation of the basalt fiber reinforcement mesh was detrimental to the interlayer shear properties.关键词
