摘　　要：利用高速剪切乳化机将塑料大棚薄膜作为沥青改性剂制备改性沥青,塑料大棚薄膜掺量分别为0%、3%、6%和9%,对塑料大棚薄膜改性沥青进行动态剪切流变试验,研究其流变特性。试验结果表明:塑料大棚薄膜改性沥青的复模量因子得到了明显提高,相位角有所降低,塑料大棚薄膜改性沥青具有较好的高温抗变形性能。The modified asphalt was prepared by using plastic greenhouse film as asphalt modifier in high speed shear emulsifier.The content of plastic greenhouse film was 0%,3%,6%and 9%,respectively.The rheological properties of plastic greenhouse film modified asphalt were studied by dynamic shear rheological tests.The test results show that the complex modulus factors of the asphalt modified by plastic greenhouse film have been increased obviously,and the phase Angle has been reduced,and the asphalt modified by plastic greenhouse film has better high temperature deformation resistance.
