摘要
主要介绍沥青材料的组分试验原理,针对盘锦基质沥青和掺加四种国内外典型天然沥青(包括四川天然沥青、新疆天然沥青、北美的岩沥青以及南美的湖沥青)的改性沥青进行组分分析及其与25℃针入度、软化点和10℃延度三大指标进行相关性分析,探讨天然沥青对石油沥青性能的影响规律。
The test principle of component of asphalt material is mainly introduced, component analysis on Panjin matrix asphalt and modified asphalt of mixing with four kinds of home and abroad typical natural asphalt （ including Sichuan natural asphalt, Sinkiang natural asphalt, rock asphalt of Northern America and lake asphalt of South America） and correlation analysis on three indexes like 25℃ thixotropic index, softening point and 10℃ ductility are made, and influencing law of natural asphalt on petroleum asphalt performance is discussed.
