Self-cleaning hole durable drainage pavement structure and laying method thereof
The invention belongs to the technical field of road engineering, and particularly discloses a self-cleaning hole durable drainage pavement structure and a laying method thereof.The self-cleaning hole durable drainage pavement structure comprises a pavement unit and a drainage unit, and the pavement unit comprises an upper surface layer, a bonding layer, a middle surface layer, a waterproof bonding layer, a lower surface layer, a stress absorption layer and a base layer which are sequentially arranged from top to bottom; the upper surface layer is made of a super-elastic porous mixture, the bonding layer is made of polyurethane modified emulsified asphalt, the middle surface layer is made of a porous asphalt mixture, the waterproof bonding layer is made of hot-sprayed modified asphalt, the lower surface layer is made of a high-modulus asphalt mixture, the stress absorbing layer is made of rubber asphalt mortar, and the base layer is made of cement stabilized macadam. And the height of the drainage unit is lower than that of the waterproof bonding layer. According to the technical scheme, the drainage pavement structure has the self-hole-cleaning capacity, the anti-blocking capacity and the anti-heavy-load capacity are high, and dual durability of the structure and the function can be achieved.
本发明属于道路工程技术领域，具体公开了一种自清孔耐久型排水路面结构及其铺设方法，包括路面单元和排水单元，路面单元包括从上至下依次设置的上面层、粘层、中面层、防水黏结层、下面层、应力吸收层和基层；上面层采用超弹多孔混合料，粘层采用聚氨酯改性乳化沥青，中面层采用多孔沥青混合料，防水黏结层采用热洒改性沥青，下面层采用高模量沥青混合料，应力吸收层采用橡胶沥青砂浆，基层采用水泥稳定碎石；排水单元的高度低于防水黏结层的高度。本技术方案的排水路面结构具备自清孔能力，抗堵塞、抗重载能力强，能够实现结构与功能的双重耐久。
