玄武岩纤维/APAO复合改性沥青高低温流变性能和抗热氧老化性能研究OACSTPCD
Research on High and Low Temperature Rheological Properties and Thermal and Oxygen Aging Resistance of Basalt Fiber/APAO Composite Modified Asphalt
为了避免或减少沥青病害出现,选取玄武岩纤维和APAO作为沥青的改性剂,成功制备了高低温流变性能以及抗热氧老化性能具佳的玄武岩纤维/APAO复合改性沥青.通过DSR以及BBR试验,研究APAO改性沥青和玄武岩纤维/APAO复合改性沥青的高低温流变性能和抗热氧老化性能,并通过高低温连续分级温度,确定玄武岩纤维和APAO的最佳掺量;通过红外光谱分析其老化机理.结果表明:APAO可明显改善沥青的高温流变性能和抗热氧老化性能;但是APAO也明显损害了沥青的…查看全部>>
In order to avoid or reduce the occurrence of asphalt disease,basalt fiber and APAO were selected as modifiers of asphalt,and basalt fiber/APAO composite modified asphalt with good high and low temperature rheological properties and anti-heat and oxygen aging properties was successfully prepared.Through the DSR and BBR tests,the high and low temperature rheological properties and anti-heat and oxygen aging properties of APAO-modified asphalt and basalt fiber…查看全部>>
