抗老化性能

• On the basis of the past achievement all over the world , the effect of aging on softening temperature , penetration and ductility . the relationship between the dosage of rubber powder and aging properties , the size of rubber powder and aging properties were studied . the feasible method to improve the aging properties of asphalt was found
  通过试验结果分析对比给出沥青的耐老化性与废橡胶粉掺量的关系、沥青的耐老化性与废橡胶粉粒径的关系,从而得出提高废橡胶粉改性沥青抗老化性能的有效措施。
