基于多年研究数据,分析了不同天然沥青的组成和特点,认为不同天然沥青的性能差别与沥青含量、灰分含量存在密切关联,老化性能与油分含量、沥青质微观结构有关。湖沥青由于矿物组成多为火山灰成分,体现出与天然岩沥青不同的改性效果,并在沥青混合料的综合性能上更具优势,低温性能和耐疲劳性能尤为突出。

Based on years of research data, the composition and characteristics of different natural bitumen are reviewed. It is considered that the difference of performance of different natural bitumen is closely related to asphalt content and ash content. Aging property is related to oil content and microstructure of asphaltene. Because the mineral composition of lake asphalt is mostly volcanic ash, it shows different modification effect from natural rock asphalt, and has more advantages in the comprehensive performance of asphalt mixt...
