The use of synthetic fibres has been reported to enhance the performance of asphalt pavement materials in terms of permanent deformation, fatigue and thermal cracking. However, limited results about the benefits of synthetic fibres in the reinforced warm-mix asphaltic materials, and the exact mechanism of reinforcing the binding part in pavement structures is still unclear. In this contribution, a semi-circular bending test was per-formed by using various fibre amounts as well as fibre length inside the bituminous mix. The results indicate that the inclusion of fibre can improves the warm-mix performance. Tensile strength as the first criterion is en-hanced proportionally by increasing fibre dosage. The reinforcing effect brought by 38-mm fibre is higher than the one with 19-mm.
