Novel environment-friendly asphalt and asphalt mixture modifier and construction method thereof

The invention discloses a novel environment-friendly asphalt and asphalt mixture modifier, comprising, by weight, 50-80 parts of a macromolecular carbon-containing compound, 10-25 parts of macromolecular resin, and 5-15 parts of an organic acid. The invention also discloses a preparation method and construction method of the modifier. The invention provides the novel multifunctional environment-friendly asphalt and asphalt mixture modifier that may replace SBS (styrene-butadiene-styrene) modifiers; the preparation and application processes of the modifier are simple and environmentally friendly, and the modifier has stable properties, long shelf life and low energy consumption and is applicable to various asphalt mixtures. The modifier can ensure that various pavement performances of the asphalt mixtures are not lower than those of SBS modified asphalt, the production process is simple, and energy saving, emission reduction and pollution reduction are truly achieved. 本发明公开了种新型环保沥青及沥青混合料改性剂,由下列重量份数的各组份组成：高分子含碳
