| 摘 要： | 文章针对印尼产Buton岩沥青的特性，对不同掺量的岩沥青改性沥青混合料和复合改性沥青混合料SMA-10的水稳定性、高温稳定性和低温抗裂性分别进行室内对比试验研究。结果表明，随着岩沥青掺量的增加，岩沥青改性混合料和复合改性沥青混合料的水稳定性、高温稳定性和低温抗裂性等路用性都能改善明显，其中，以岩沥青掺量为沥青混合料质量的3％时，综合路用性能改善效果最好。

| Abstract: | Based on the characteristics of Buton Rock Asphalt produced from the Indo- nesian, we researched on water stability, high temperature stability and low tempera - ture anti--cracking for different dosage modified asphalt rock asphalt and composite modified asphalt mixture SMA - 10, with the comparative experimental study indoor. The results show that the pavement performances of water stability, high temperature stability, low temperature anti--cracking ,of the rock asphalt modified asphalt mixtures and the composite modified asphalt mixtures： increase obviously with the increase of Buton Rock Asphalt mixing content. Among them,the best improvement effect of com - prehensive pavement performances is the asphalt mixture with the Buton Rock Asphalt mixing content of 3%. |
