摘要
采用X射线衍射分析、四组分分析、溶解度试验等方法,探讨了四川某天然沥青的物质组成,计算了其芳香化程度及结构参数,初步判断了其所属类别;从物化性能方面,探讨了该天然沥青在路用工艺中的适用性,确定了其在道路工程应用上应注意控制的几个主要指标.
The composition, aromaticity, structure parameters and category of natural asphalt were studied by the XRD analysis, four composition analysis and solubility experiments. Finally, the technical applicability in pavement of natural asphalt was discussed in physical and chemical aspects, and some important factors of natural asphalt in pavement use were put forward.
