Zusammenfassung:The invention discloses a composite anti-crack noise-reduction durable asphalt pavement structure which comprises a base layer, a bonding layer, a rubber particle flexible asphalt concrete layer, a high-modulus asphalt concrete layer and a small-particle-size wearing layer which are sequentially covered from bottom to top. Large-particle rubber with the particle size of 3-8 mm is added into the rubber particle flexible asphalt concrete layer, so that the flexibility of asphalt concrete is greatly improved, the asphalt concrete has large deformability, on one hand, reflection cracks can be effectively prevented, on the other hand, the asphalt concrete has a strong absorption effect on vibration in the vehicle driving process, the driving noise is low, and the service life of the vehicle is prolonged. A large number of waste tires can be consumed, and the environment is protected; the high-modulus asphalt concrete layer is high in strength, high in load bearing capacity and high in durability; according to the
