摘要
生物沥青是相对于石油沥青的一种新型材料,它由生物质快速热裂解制备生物油,继而制备而成。生物油是生物沥青的基础,因此首先分析了生物油的制备机制及生物油的组成和性质,然后阐述了生物沥青的制备方法与应用方式,并总结了国内外生物沥青结合料和混合料的研究现状及发展前景。现有研究表明,生物沥青具有较好的使用性能,加之其具有经济环保、可再生等石油沥青无法比拟的优点,必将成为未来道路用沥青材料研究发展的新方向。
Relative to petroleum asphalt, pyrolysis of biomass. Since bio-oil is the basis of bio-asphalt is a new material, which is prepared by bio-oil from fast bio-asphalt, the preparation mechanism of bio-oil and the composition and properties of bio-oil are firstly analyzed, and then the preparation methods and application ways of bio-asphalt are illustrated, in addition, current research situation and development prospects of bio-asphalt binder and mixture are concluded at home and abroad. Existing researches show that bio-asphalt has a good performance, and the advantages of being economical, environmental friendly and renewable, which petroleum asphalt can not be comparable with, so bio-asphalt will become a new direction of future researches and development of road asphalt materials.
