摘　　要：通过开发先改性后乳化工艺生产的乳化改性沥青,并作为防水黏结剂使用于复合式刚柔性隧道路面的防水黏结层,经过实验室组合结构拉拔及组合结构剪切试验,得出乳化改性沥青渗水系数低,与水泥混凝土拉拔强度可达1.5 MPa以上,组合结构拉拔强度达0.58 MPa,组合结构剪切能够达1.28 MPa,乳化改性沥青可以作为一项优良的防水黏结剂使用于复合式刚柔性隧道路面中。Through the development of emulsified modified asphalt produced by the process of first modification and then emulsification,and used as waterproof binder in the waterproof bonding layer of composite rigid flexible tunnel pavement,through the laboratory combined structure drawing and composite structure shear test,it is concluded that the emulsified modified asphalt has low water permeability coefficient,the pull-out strength with cement concrete can reach more than 1.5 MPa,and the pull-out strength of composite structure can reach 0.58 MPa The shear strength of the composite structure can reach 1.28 MPa.The emulsified modified asphalt can be used as an excellent waterproof binder in the composite rigid flexible tunnel pavement.
