Fiber reinforced plastic reinforced permeable asphalt pavement structure
The invention belongs to the technical field of road structure design, and provides a fiber reinforced plastic reinforced permeable asphalt pavement structure which is constructed step by step from the lower layer to the upper layer, a pavement base layer is laid on a conventional roadbed, and arrangement and construction of drainage ditches/pipes are considered. And an integral water-resisting layer covers the surface of the pavement base layer and extends to the drainage ditch/pipe. A first layer of FRP ribs is transversely or longitudinally arranged on the integral water-resisting layer according to a certain interval, then a second layer of FRP ribs is arranged in the vertical direction, and the intersection of the two layers of FRP ribs is fixed in a bonding or binding mode to form an FRP rib layer. And a permeable asphalt pavement layer is laid on the FRP rib layer. The water-permeable asphalt pavement can be matched with the cement concrete base layer, the drainage effect is achieved, and meanwhile the overall stability of the pavement structure is improved. For a rainy area, the risk of roadbed settlement caused by rainwater permeation can be greatly reduced, the distributed drainage effect of an overall road network can be achieved, and the water accumulation degree of a low-lying area during rapid rainfall is reduced.
本发明属于道路结构设计技术领域，提供了一种纤维强化塑料加筋透水沥青路面结构，由下层向上逐步施工，在常规路基上，铺设路面基层，同时考虑排水沟/管的设置及施工。整体隔水层覆盖路面基层表面，且延伸至排水沟/管。整体隔水层上按一定间距横向或纵向布置第一层FRP筋，之后在垂直方向布设第二层FRP筋，两层FRP筋交叉处以粘接或绑扎方式固定，构成FRP筋层。在FRP筋层之上，铺设透水沥青路面层。本发明可以实现透水沥青路面与水泥混凝土基层搭配，起到排水作用的同时，又提高了路面结构整体稳定性。对于多雨地区，可大大降低雨水渗透引起路基沉降风险，亦可起到整体路网分布式排水作用，降低急降雨时低洼地区积水程度。
