Embodiment 1
[0020] Example 1: The melting point of the polyethylene resin used is between 120-130°C, the melting point of the polypropylene resin is between 160-170°C, the mass ratio between the polyethylene resin and the polypropylene resin is 95:5, first stir evenly , put it into TE-50 twin-screw extruder, melt and shear and mix at 180-200°C to make a homogeneous substance, and then extrude through a nozzle to make an extrudate. After cooling and shaping, the extruded product is pelletized on a granulator and then air-dried. The properties of the prepared additive sample are as follows: elastic modulus 103.8MPa, tensile strength 14.67MPa, elongation at break 433.3%, impact strength 51.97×10 3 J.m. -2 , Melt index 1.6513g / 10min. After the additive was mixed with the asphalt concrete aggregate at 180°C at a mass ratio of 6‰, the rutting resistance test was 63,000 times / mm.
Embodiment 2
[0021] Example 2: The melting point of the polyethylene resin used is between 120-130°C, the melting point of the polypropylene resin is between 160-170°C, the mass ratio between the polyethylene resin and the polypropylene resin is 90:10, first stir evenly , put the above composition into a TE-50 twin-screw extruder, melt and shear and mix it at 180-200°C to make a homogeneous substance, and then extrude it through a nozzle to make an extrudate. After cooling and shaping, the extruded product is pelletized on a granulator and then air-dried. The properties of the prepared additive sample are as follows: elastic modulus 154.7MPa, tensile strength 15.46MPa, elongation at break 383.4%, impact strength 52.87×10 3 J.m. -2 , Melt index 1.5876g / 10min. After the additive was mixed with the asphalt concrete aggregate at a mass ratio of 6‰ at 180°C, the anti-rutting test did not produce obvious deformation within 60 minutes.
Embodiment 3
[0022] Example 3: The melting point of the polyethylene resin used is between 120-130°C, the melting point of the polypropylene resin is between 160-170°C, the mass ratio between the polyethylene resin and the polypropylene resin is 80:20, first stir evenly , put the above composition into a TE-50 twin-screw extruder, melt and shear and mix it at 180-200°C to make a homogeneous substance, and then extrude it through a nozzle to make an extrudate. After cooling and shaping, the extruded product is pelletized on a granulator and then air-dried. The properties of the prepared additive sample are as follows: elastic modulus 215.7MPa, tensile strength 18.36MPa, elongation at break 434.4%, impact strength 53.67×10 3 J.m. -2 , Melt index 1.6465g / 10min. After the additive was mixed with the asphalt concrete aggregate at 180°C at a mass ratio of 6‰, the rutting resistance test was 3706 times / mm.
