国产天然岩沥青微观结构分析及性能研究

摘要

对国产天然岩沥青进行实验研究，通过凝胶渗透色谱法分析国产天然岩沥青的元素组成。以90#沥青为基质沥青，采用国产天然岩沥青与特立尼达湖沥青对其改性，对比测试了改性沥青的性能，对国产天然岩沥青在基质沥青中所起到的作用从机理方面进行研究。%It has researched Chinese-made natural rock asphalt, and analyzed the content of element using gel chromatography. It has compared the performance of modified natural rock asphalt and Trinidad Lake modi- fied asphalt and researched Chinese-made natural rock asphalt in the asphalt from the mechanism.
