为了探究木质素纤维和RAP料掺量对温拌再生沥青混合料路用性能的影响，对不同RAP料掺量下木质素纤维温拌再生混合料的性能进行分析，采用动稳定度、破坏最大应变、残留稳定度和TSR等指标对纤维再生沥青混合料的路用性能进行评价分析。结果表明，温拌再生沥青混合料的高温稳定性与RAP料掺量成正比，低温和水稳定性能与其成反比，木质素纤维具备加筋、增黏、阻裂和增韧等作用，可有效提升温拌再生混合料的性能，使其满足规范要求。

In order to explore the influence of lignin fiber and RAP content on the road performance of warm-mixed recycled asphalt mixture, the performance of lignin fiber warm-mixed recycled asphalt mixture with different RAP content was analyzed, and the road performance of fiber recycled asphalt mixture was evaluated and analyzed by using dynamic stability, maximum strain to failure, residual stability and TSR.The results show that the high temperature stability of warm-mixed recycled asphalt mixture is directly proportional to the content of RAP,and the low temperature and water stability are inversely proportional to it.Lignin fiber has the functions of reinforcement, viscosity enhancement, crack resistance and toughening, which can effectively improve the performance of warm-mixed recycled asphalt mixture and make it meet the requirements of the specification.
