摘　　要：采用多指标正交试验,模拟路面施工时的压实温度,运用极差分析法和综合平衡法确定了纤维沥青砼生产和施工的优化方案,通过马歇尔试验研究,阐述了干拌法、湿拌法和后拌法等3种拌和工艺的特点,分析了3种拌和工艺和压实温度对纤维沥青砼马歇尔指标的影响.在此基础上对纤维沥青砼的生产和施工提出了一些建议.The model-temperature in road construction is simulated by multi-index orthogonal test, and the characteristics of three mixing methods including the dry-mixing method, wet-mixing method and compound-mixing method are elaborated, and the effects of different mixing methods and model temperatures on Marshall index of fiber-enhanced asphalt concrete are analysed in Marshall test. At last, some advices on the production and construction of the fiber-enhanced asphalt concrete are given.
