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。
The rare earth compound additives were added to the rubber modified asphalt, the effects of the addition amount and overall proportion on the asphalt performance were studied. Research shows that the trace addition of rare earth composite additives can help improve the high ultraviolet absorption of asphalt. The asphalt pavement thus prepared can better adapt to the natural conditions of long northern sunshine time.
