Composite anti-crack noise-reduction durable asphalt pavement structure and implementation method thereof
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 invention, the advantages of each structural layer can be fully and comprehensively exerted, and the pavement structure has the advantages of crack resistance, noise reduction, durability and the like.
本发明公开了一种复合式抗裂降噪耐久沥青路面结构，其包括按照从下至上的顺序依次覆盖的基层、粘结层、橡胶颗粒柔性沥青混凝土层、高模量沥青混凝土层和小粒径磨耗层。在橡胶颗粒柔性沥青混凝土层中加入粒径为3～8mm的大颗粒橡胶，使沥青混凝土柔性大幅提升，具有较大变形能力，一方面可以有效防止反射裂缝的出现，另一方面对车辆行车过程中的振动具有较强吸收作用，行车噪声低，而且可以消耗大量的废旧轮胎，保护环境；高模量沥青混凝土层的强度高，承受荷载能力强，耐久性高；小粒径磨耗层具有耐磨耗，本发明能充分综合发挥各结构层的优势，实现路面结构具有抗裂、降噪、耐久等的优点。
