纤维沥青低温性能影响因素的试验研究

随着材料加工技术的不断进步,聚合物增强纤维的性能有了很大的提高,其应用也越来越广泛,在沥青混合料中掺加纤维成为提高沥青混合料使用性能的重要手段。为研究纤维的改善效果及机理,本文通过SHRP研究计划开发BBR、DTT试验设备研究了纤维长度及纤维掺量对纤维沥青低温性能的影响,可为纤维沥青混合料中纤维种类的选择及用量的确定提供参考。

Experiment Study for Performance of Asphalt Reinforced with FiberAt Low Temperature

With significant improvements in materials processing technologies,the performance of polymer fiber has been greatly improved,and been applied widespread,and It's an important way to improve performance of asphalt mixture by adding polymer fiber.BBR and DTT was applied to study the effect of fiber length and fiber concentration to fiber reinforced asphalt at low temperature for study the modified affection and reinforced mechanism.The result can be applied to be a reference to select fiber type and fiber co...
