This paper for the first time presents an experimental study on flexural fatigue behaviour of concrete reinforced with mixed RTPF considering different fibre dosages (i.e., 1.2, 2.4, 4.8 and 9.6 kg/m^{3} ). Results indicate that with the presence of RTPF, the flexural strength of concrete was increased by 3.6-9.6%. The fatigue life of all mixtures followed the two-parameter Weibull distribution and can be accurately predicted using the developed double-logarithm fatigue equations. Concrete reinforced with 4.8 kg/m^{3} of RTPF presented the longest fatigue life under different failure probabilities. RTPF and polypropylene fibre (PPF) reinforced concrete exhibited similar fatigue failure mechanisms. 0.2-0.4% V_{f} of RTPF could substitute around 0.1% V_{f} of PPF in concrete considering overall static, dynamic and fatigue performance. date: 2020-01 date_type: published publisher: Elsevier official_url: https://doi.org/10.1016/j.cemconcomp.2019.103441 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Journal Article verified: verified_manual elements_id: 1711517 doi: 10.1016/j.cemconcomp.2019.103441 language_elements: English lyricists_name: Zhang, Mingzhong lyricists_name: Zhong, Hui lyricists_id: MZHAA72 lyricists_id: HZHON46 actors_name: Zhang, Mingzhong actors_id: MZHAA72 actors_role: owner full_text_status: public publication: Cement and Concrete Composites volume: 105 article_number: 103441 issn: 0958-9465 citation: Chen, M; Zhong, H; Zhang, M; (2020) Flexural fatigue behaviour of recycled tyre polymer fibre reinforced concrete.
