摘　　要：采用熔融共混法制备了层状双羟基复合金属氧氧化物LDHs耐老化沥青,研究了LDHs对沥青耐老化性能的影响。制备了LDHs耐老化沥青薄膜,通过沥青薄膜光学性能研究揭示了LDHs与沥青的作用机理。结果表明,LDHs可有效提高沥青的抗紫外老化性能。Layered double hydroxides （LDHs） modified asphalt was prepared by melt blending. The effect of LDHs on UV-aging properties of modified asphalt was studied. The LDHs modified bitumen film was prepared. The mechanism between LDHs and bitumen was investigated by the optical property of bitumen film. The results showed that LDHs can effectively improve the UV-aging resistance of bitumen.
