摘要
通过热处理技术,对沥青进行改性试验,提高了沥青的软化点及甲苯不溶物含量,改性后沥青可满足建筑沥青使用要求。
Property modification of lignitic tar asphaltum was studied based on its property and composition. The inteneration and toluene insoluble materials of asphaltum were increased trough heat treatment, and the modified asphaltum could be used in architecture.
