摘要
文章结合参考文献研究成果,就印尼产Buton岩沥青和新疆产岩沥青对沥青混合料的低温性能的影响进行对比试验研究,结果表明:Buton岩沥青能够有效提高沥青混合料的低温抗裂性,而新疆岩沥青改善作用甚微;可以通过与SBS复合改性、增加沥青用量、采用SMA级配类型等来综合改善新疆岩沥青改性沥青混合料的低温抗裂性能。
Combined with the study result in relative literature,the article compares the influence of Indonesian Buton and Xinjiang rock asphalt on the low tempreature anti-cracking performance of asphalt mixture.The results show that the Buton rock asphalt can improve the low temperature performance effectively,while the Xinjiang rock asphalt can improve a little;with SBS combined modified,with dosage of asphalt Increased,with SMA type can improve the low temperature crack resistance of Xinjiang modified asphalt mixture.
