摘要
石油沥青是当前沥青路面建设与养护工程不可或缺的材料。作为一种不可再生资源,石油沥青替代材料研究具有重要的环保与经济价值和战略意义。综述了以木质纤维、动物粪便、地沟油等作为生物质来源制备生物沥青的工艺,分析了不同种类生物沥青的技术性能及用途。目前,生物沥青主要作为石油沥青的添加剂或改性剂使用,完全替代石油沥青仍需要进一步研究。
Petroleum asphalt is an indispensable material for the construction and maintenance of asphalt pavement. As a kind of non - renewable resources, the research of petroleum asphalt substitute material has important environmental and economic value and strategic significance. In this paper, the process of preparing bio - asphalt, using wood fiber, animal manure and swill - cooked oil as the source of biomass, was de- scribed. The technical properties and application of different types of bio - asphalt were analyzed. At present, the bio - asphalt is mainly used as additive or modifier of petroleum asphalt. Hence, further research on the complete replacement of petroleum asphalt by bio- asphalt is needed.
