Laying structure and laying method of single-component polyurethane noise-reducing pavement
The invention belongs to the technical field of road engineering, and particularly discloses a paving structure and a paving method of a single-component polyurethane noise-reducing pavement. The structure is characterized in that a composite pavement structure is adopted, the surface layer of the composite pavement structure is a polyurethane mixture anti-skid wearing layer, the lower layer of the composite pavement structure is a polyurethane mixture OGFC noise reduction drainage layer, the lower layer of the composite pavement structure is a large-particle-size asphalt macadam mixture drainage anti-crack layer, and the lowest layer of the composite pavement structure is an SBS modified asphalt mixture anti-fatigue layer. Compared with the prior art, the laying structure of the composite noise reduction pavement is developed for solving the problems that a traditional noise reduction pavement is poor in durability, the noise reduction effect is difficult to continue and the like, the noise reduction function of the pavement structure is guaranteed, and meanwhile the continuity of the noise reduction capacity of the pavement structure can be guaranteed; and the problems that a traditional noise reduction pavement cannot resist reflection cracks of a cement stabilized macadam base and cannot effectively maintain the noise reduction capacity are solved, and the pavement paving structure has the effects of continuously reducing noise and resisting reflection cracks and fatigue diseases.
本发明属于道路工程技术领域，具体公开了一种单组分聚氨酯降噪路面的铺设结构及铺设方法。该结构的特点是采用复合路面结构，其表面层是聚氨酯混合料抗滑磨耗层，下层是聚氨酯混合料OGFC降噪排水层，再下层是大粒径沥青碎石混合料排水抗裂层，最下层是SBS改性沥青混合料抗疲劳层。与现有技术相比，本发明针对传统降噪路面耐久性差，降噪效果难以持续等问题，开发了一种复合式降噪路面的铺设结构，在保障路面结构降噪功能的同时，也能够保障路面结构降噪能力的持续性，以及解决传统降噪路面无法抵抗水泥稳定碎石基层的反射裂缝，无法有效保持降噪能力的问题，是一种具有持续降噪、抵抗反射裂缝和疲劳病害的路面铺设结构。
