《新时代的中国绿色发展》明确指出，提升交通基础设施绿色化水平。路面材料的绿色化是绿色公路建设的关键。生物沥青是将由废弃生物质经高温热裂解提炼的生物重油与石油沥青混溶或向生物重油掺加其他外掺剂，制备而成的结合物；具有低温性好、黏附性优等特点；能够实现废弃生物质变废为宝，绿色可再生。但生物质来源较多，生物沥青高温性能偏弱、老化性能不足、表征手段局限等制约着其产业化应用。本议题围绕诸类内容展开研讨，旨在激发创新、凝聚共识，为绿色公路建设增砖添瓦。

China's Green Development in the New Era clearly points out that transport infrastructure for green development should be upgraded. The greening of pavement materials is the key to the construction of green highways. Bio-asphalt is a combination prepared by bio-oil extracted from waste biomass with petroleum bitumen or by adding bio-oil with other external additives. It has good low temperature and excellent adhesion. It can realize the transformation of waste biomass into treasure, thus it's green and renewable. However, there are many sources of biomass, and the high-temperature performance of bio-asphalt is weak, the aging performance is insufficient, and the characterization methods are limited; these features restrict its industrial application. This topic focuses on these contents, aiming to stimulate innovation, build consensus, and promote the development of green roads.
