根据油砾石路面结合料的技术要求,选取兰炼油浆作为降粘剂;分别在兰炼110号沥青和克拉玛依90号沥青中添加不同比例的油浆,通过实测得出不同掺配比例结合料60℃的运动粘度值,与掺稀降粘理论计算粘度值相比较,证明油砾石路面结合料可以通过掺稀降粘技术实现,油浆可作为轻质溶剂混合到沥青中使用;通过结合料15℃的针入度试验、蜡含量试验和旋转薄膜烘箱老化试验确定油砾石路面结合料油浆与沥青的掺配比例。
According to the technical requirements of the oil-gravel pavement binder, select the blue refining slurry as a viscosity reducer; respectively, in Lan Lian No. 110 asphalt and Karamay No. 90 asphalt to add different proportions of oil slurry, obtained by measuring different blending ratio of binder 60 ℃ kinematic viscosity value, compared with the dilute viscosity theory calculated viscous value compared to prove that the oil and gravel road binder can be achieved by dilute dilute viscosity technology, slurry can be used as a light solvent mixed into the asphalt; through the binder 15 ℃ penetration test, wax content test and rotating film oven aging test to determine the proportion of oil-gravel pavement mixture slurry and asphalt blending.
