【摘要】 随着原油多变、炼化水平及添加剂技术的进步,加之沥青复杂的组成,道路沥青的研究方法也急需革新。为进一步完善沥青分子结构、元素成分及微观形貌等方面的信息,从不同角度对沥青研究方法进行了综述,包括分子结构及机理研究、微观形貌表征、理论模拟计算及其它较为常用的研究方法,分析了这些方法在沥青的表征及其老化、愈合及环境污染等方面的应用现状,并为今后沥青的研究重点提出了展望。更多还原

【Abstract】 With the variation of crude oil,the progress of oil processing and additive technology,the complex composition of asphalt,research method of road asphalt is in urgent need of innovation.In order to further understand the molecular structure,elemental ingredients and micro-morphology of asphalt,the asphalt research methods are reviewed from different angles,including molecular structure and mechanism research,micro-morphology,theoretical simulation and other common research methods.The application status of these methods in asphalt characterization,aging,healing and environmental pollution were analyzed.In addition,the prospect of asphalt research focus in the future is pointed out.更多还原
