天然纤维沥青混合料研究与应用进展.

Natural fiber is a sustainable bio-renewable resource, which can improve the overall road performance of asphalt mixture, especially the anti-cracking and anti-fatigue performance. It delays the early disease of asphalt pavement and has good application prospect. The article introduces the characteristics of natural fibers and the performance enhancement mechanism of fiber asphalt mixtures, reviews the latest research results of natural organic plant fibers and inorganic mineral fibers in asphalt mixtures. In the future, the research and application of plant fibers such as waste fibers and non-wood fibers in pavement should be strengthened, and the problems of compatibility, hydrophilicity and thermal stability of plant fibers should be explored from the surface modification of fibers; in addition, basalt fiber is a high-performance natural inorganic mineral fiber, and its enhancement mechanism and effect on asphalt concrete performance should be studied from the aspects of composite modification, and the research on ceramic fiber or other non-polluting mineral fiber should be strengthened to broaden the choice of polluting high-performance fibers for road, to promote the development of high-performance asphalt mixtures and achieve long life of asphalt pavement.
