Long-life asphalt pavement structure based on particle activated natural asphalt high-modulus mixture

The utility model discloses a long-life asphalt pavement structure based on a particle activated natural asphalt high-modulus mixture. The long-life asphalt pavement structure comprises a graded broken stone subbase layer, an EME-20 asphalt concrete base layer, an EME-16 asphalt concrete lower surface layer and an SMA-13 asphalt concrete upper surface layer which are paved from bottom to top, the EME-20 asphalt concrete base layer and the EME-16 asphalt concrete lower surface layer are both particle activated natural asphalt binder layers. The particle activated natural asphalt binder layer is adopted as the base layer and the lower surface layer, and the particle activated natural asphalt binder layer has high modulus, good load transmission and dispersion capacity and excellent high-temperature stability, water stability and anti-fatigue performance, so that the use performance of the asphalt pavement is improved, the service life of the asphalt pavement is prolonged, and the service life of the asphalt pav
