    Performance evaluation of stone mastic asphalt (SMA) mixtures with textile waste fibre
    (Elsevier, 2024) Rodríguez, Wilder; Rivera, José Julián; Sevillano, Miguel; Torres, Tania
    The research evaluates the performance of Stone Mastic Asphalt (SMA) mixtures using residual cotton fibres from the Peruvian textile industry to address the environmental pollution caused by this sector. A reference SMA20 mixture was established with 0.30% commercial fibre and 6% asphalt. Subsequently, this fibre was replaced by textile fibre in the same proportions. It was found that 0.20% textile fibre optimally met the volumetric requirements and binder drainage tests. Performance tests showed that the textile fibre achieved a TSR of 95%, compared to 82% for the commercial fibre, and a rutting resistance of 2.82 mm compared to 2.46 mm for the commercial fibre. Additionally, the textile fibre demonstrated a better dynamic modulus at high temperatures. In conclusion, residual Peruvian cotton fibres can efficiently replace commercial fibres in SMA20 mixtures, with 0.20% being the optimal amount, thus promoting sustainable material reuse.
