摘　　要：将稀土复合助剂添加到胶粉改性沥青中,研究了添加量、整体配比对沥青性能的影响。研究表明,稀土复合助剂的微量加入,有助提高沥青高紫外线吸收性能。据此制成的沥青路面更能适应北方日照时间长的自然条件。In this paper,rare earth additives were added to crumb rubber modified asphalt. The effect of addition level and overall ratio on the properties of crumb rubber modified asphalt was investigated. Results showed that trace rare earth additives improved ultraviolet absorption of asphalt. So this asphalt adapted readily to long duration of sunshine in the northern area of China.
