摘要: 为研究聚酯纤维对透水沥青混凝土冲击压缩性能的影响，采用∅74 mm钢质分离式霍普金森压杆装置对掺杂不同质量分数的聚酯纤维透水沥青混凝土进行冲击压缩实验。在静态和4个应变率下的实验结果表明，透水聚酯纤维沥青混凝土是应变率敏感性材料，具有较强应变率效应。透水聚酯纤维沥青混凝土具有较好的延展性，动态应力应变曲线分为3个阶段：弹性变形阶段、塑性变形阶段和破坏阶段。当应变率相同时，随着掺杂聚酯纤维质量分数的增大，透水沥青混凝土的冲击抗压强度呈现出先升高后降低的变化规律，掺杂聚酯纤维的质量分数为0.40%时，冲击抗压强度达到最大。冲击抗压强度约为静态抗压强度的8~13倍。Abstract: In order to investigate the influence of polyester fiber on impact characteristics of permeable asphalt concrete, ∅74 mm steel SHPB apparatus is adopted to conduct impact compressive test with various strain rates and different polyester fiber contents. The results of specimens under static condition and dynamic conditions with four strain rates show that the permeable polyester fiber asphalt concrete is a material sensitive to the change of the strain rate and exhibits a significant strain rate effect. It has good ductility and dynamic stress-strain curve that is characterized by three stages: Elastic deformation, plastic deformation and failure. When the strain rate remains the same, the impact compressive strength of permeable asphalt concrete first increases and then declines with the increase of the polyester fiber content. At this time it shows an optimum polyester fiber content of 0.40% and its impact compressive strength reaches its maximum. The impact compressive strength is about 8-13 times as large as the static compressive strength.
