摘要：通过配制的沥青一橡胶来检验胶粉对沥青的改性性能，试验证明其具有良好的改性性能，尤其是沥青与集料粘附性的改善更为显著。通过沥青一橡胶拌制的沥青玛蹄脂碎石(SMA)分析废旧胶粉对混合料性能的影响，结果表明混合料具有良好的高温性能与水稳性，胶粉在一定程度上可以替代纤维稳定沥青，从而降低建设成本。

Performance research of SMA mixture using asphalt and rubber

Abstract: Modification of asphalt is done using asphalt and rubber. The test shows that the asphalt a
nd rubber have better modification properties, special for adhere property. The influences of waste and old binding powder upon mixtue performance of asphalt and rubber SMA are analyzed. The results show that the mixture has better high temperature property and water stability. The binding powder can replace fibre asphalt to some extent, and which can decrease the construction cost.
