摘要
以埃索70″沥青作为基质沥青，对不同掺量的印尼布敦岩沥青改性沥青的性能进行了研究，试验结果表明，随着岩沥青掺量的增加，改性沥青的抗变形能力、感温性能、高温性能和低温性能得到提高．同时，岩沥青为天然沥青且不含蜡，可有效提高改性沥青的抗老化能力．据此推荐了改性沥青综合性能优良的岩沥青，其适宜掺量为10％～20％，从而为岩沥青的应用提供了参考．
The performances of modified asphalt with different contents of Indonesian Buton Rock Asphalt （BRA） and Esso based dasphalt A-70 are studied with the experiments. The results show that the capacity of anti-deforming and the performances of temperature sensibility,in high temperature or low temperature are improved as the contents of BRA increase. In addition, BRA is a kind of nature asphalt and has no wax, so it can effectively increase the anti-aging capacity of the modified asphalt. According to the analysis, the appropriate BRA contents of the modified asphalt are recommended as 10% - 20% with good comprehensive performances to provide a basis for the application of BRA.
