摘要
通过对基质沥青和改性沥青的组分分析,认为天然沥青具有高含量的沥青质和胶质,掺入石油沥青中能够很大程度改变原有基质沥青的组分比例,形成新的沥青胶体体系和组成结构,抗高温能力得到很大的改善,尤其是四川天然岩沥青最为突出。
Through component analysis of the asphalt ma- terials, it can be find that natural asphalt contains more asphaltenes and resin. Incorporation of petroleum asphalt can greatly change the original matrix asphalt component proportion, form new asphalt colloid system and composi- tion. High -temperature durability have been greatly im- proved, especially the most prominent Sichuan natural rock asphalt
