本文主要通过颗粒状木质素纤维以及普通絮状木质素纤维在SMA路面设计中各项路用性能试验的对比,以及在云南大理至丽江高速公路实际施工过程中施工工艺的比较,研究颗粒状木质素纤维在SMA路面应用中的优缺点。结果表明,颗粒状木质素纤维在SMA路面施工中具有良好的稳定性、分散性以及均匀性,并能够较好的保证SMA路面的施工质量。旨在为未来的SMA路面设计、施工提供经验借鉴。 In this paper, mainly through the particulate lignin fibers and ordinary flocculent lignin fiber in the pavement design of the road performance comparison of various tests, as well as in Yunnan Dali to Lijiang Expressway construction process of the actual comparison, the study of granular wood Advantages and Disadvantages of Fiber in SMA Pavement Application. The results show that granular lignin fibers have good stability, dispersibility and uniformity in the construction of SMA pavement, and can better ensure the construction quality of SMA pavement. Designed for future SMA pavement design, construction experience to learn from.
