Composite noise-reducing asphalt pavement and preparation method thereof
The invention belongs to the technical field of road construction, and particularly relates to a composite noise reduction asphalt pavement and a preparation method thereof.The composite noise reduction asphalt pavement is composed of a base layer, a bonding layer, a flexible asphalt mixture layer and a small-particle-size uniform-texture overlay, the base layer is located at the bottom of the bonding layer, the bonding layer is located at the bottom of the flexible asphalt mixture layer, and the flexible asphalt mixture layer is located at the bottom of the small-particle-size uniform-texture overlay; the flexible asphalt mixture layer is located at the bottom of the small-particle-size uniform-texture overlay, and the flexible asphalt mixture layer is formed by mixing coarse aggregate, an asphalt mortar thermoplastic elastomer mixed layer and fine aggregate, so that the driving comfort of a driver and passengers can be greatly improved; the pavement structure combining the small-particle-size ultra-thin wearing layer and the flexible asphalt mixture can reduce driving noise and greatly improve driving comfort on one hand, and on the other hand, the pavement is compact, resistant to fatigue, not prone to water permeation and good in durability.
本发明公开的属于道路建设技术领域，具体为一种复合式降噪沥青路面及其制备方法，所述本复合式降噪沥青路面由基层、粘层、柔韧沥青混合料层和小粒径均纹理罩面构成，所述基层位于粘层的底部，所述粘层位于柔韧沥青混合料层底部，所述柔韧沥青混合料层位于小粒径均纹理罩面的底部，所述柔韧沥青混合料层由粗集料、沥青胶浆热塑性弹性体混层和细集料混合组成，可大幅度提升驾乘人员的行车舒适度，小粒径超薄磨耗层与柔韧沥青混合料结合的路面结构一方面可以降低行车噪音，大幅度提升行车舒适度，另一方面路面密实抗疲劳，不易透水，耐久性好。
