Rigid base polyurethane mixture pavement structure and paving method thereof
The invention discloses a multi-gravel polyurethane mixture, a rigid base polyurethane mixture pavement structure and a paving method thereof, and belongs to the field of road engineering. According to the invention, mineral aggregate and polyurethane are used as raw materials, and a multi-gravel polyurethane mixture is designed by adopting a multi-gravel asphalt concrete design method. The pavement structure is composed of the porous modified cement concrete base layer and the multi-gravel polyurethane concrete surface layer which are sequentially paved on the roadbed from bottom to top, is good in integral stability, high in interlayer bonding strength and obvious in cost performance advantage, and is suitable for pavement of common high-grade pavement structures.
本发明公开了一种多碎石聚氨酯混合料、刚性基层聚氨酯混合料路面结构及其铺装方法，属于道路工程领域。本发明以矿料、聚氨酯为原料，采用多碎石沥青混凝土设计方法进行多碎石聚氨酯混合料设计。本发明路面结构由自下而上依次铺筑在路基上的多孔改性水泥混凝土基层、多碎石聚氨酯混凝土面层组成，整体性稳定性好、层间联结强度高、性价比优势明显的路面结构，适用于普通高等级路面结构铺装。
