Fibres are added to asphalt surface mixes mainly due to technological reasons. The impact of loose glass fibre reinforcement on the performance characteristics of different asphalt mixes was investigated. On the one hand, the glass fibres were used at Stone Mastic Asphalts as a replacement for cellulose fibres. On the other hand, glass fibres were used as additives for asphalt concrete mixes. A constant glass fibre content of 0.5 mass-% was chosen for the laboratory tests. This paper presents the impact of glass fibres on the fatigue and stiffness performance of asphalt mixes, both determined using cyclic indirect tensile tests. The glass fibre modified asphalts investigated have high-performance characteristics, so that an application of these asphalt mixes as a tension band was examined. In order to assess the use of the glass fibre modified asphalt mixes as tension belts pavement service lifetime calculations and the economic efficiency were considered.

将纤维添加到沥青混合料中主要是由于技术原因。研究了松散玻璃纤维增​​强对不同沥青混合料性能特征的影响。一方面，Stone Mastic Asphalts 使用玻璃纤维作为纤维素纤维的替代品。另一方面，玻璃纤维被用作沥青混凝土混合物的添加剂。实验室测试选择了 0.5 质量％的恒定玻璃纤维含量。本文介绍了玻璃纤维对沥青混合料疲劳和刚度性能的影响，两者均使用循环间接拉伸试验确定。所研究的玻璃纤维改性沥青具有高性能特性，因此研究了这些沥青混合料作为张力带的应用。
