Composite permeable pavement structure capable of resisting ruts and preventing base water damage
The invention discloses a composite permeable pavement structure capable of resisting ruts and preventing base layer water damage, which comprises a lower surface layer, an upper surface layer and a lower surface layer, the lower surface layer comprises pouring type asphalt concrete paved on a base layer and an anti-seepage grouting material poured in the pouring type asphalt concrete, and the anti-seepage grouting material comprises cement, silica fume, fine aggregate, an anti-seepage modifier and water; the anti-seepage modifier comprises styrene-acrylic emulsion, a water reducing agent, an air entraining agent, a defoaming agent and talcum powder; the waterproof bonding layer is paved on the lower surface layer, and the waterproof bonding layer is made of modified emulsified asphalt; the middle surface layer is paved on the waterproof bonding layer; the upper surface layer is paved on the middle surface layer, the middle surface layer and the upper surface layer are respectively made of porous asphalt mixture, and the void ratio of the middle surface layer is larger than that of the upper surface layer. The problem that a semi-rigid base layer of a pavement structure is prone to being damaged by car dangers, ruts and cracks to cause downward water seepage of a surface layer is solved.
本发明公开了一种抗车辙防基层水损坏的复合透水路面结构，包括：下面层，包括摊铺于基层上的灌入式沥青混凝土和灌注于所述灌入式沥青混凝土中的防渗灌浆料，所述防渗灌浆料包括水泥、硅灰、细集料、防渗改性剂和水，所述防渗改性剂包括苯丙乳液、减水剂、引气剂、消泡剂和滑石粉；防水粘结层，摊铺于所述下面层上，所述防水粘结层为改性乳化沥青；中面层，摊铺于所述防水粘结层上；上面层，摊铺于所述中面层上，所述中面层和所述上面层分别为多孔隙沥青混合料，所述中面层的空隙率大于所述上面层的空隙率。本发明解决了路面结构的半刚性基层的容易车险车辙、裂缝破坏而导致面层向下渗水的问题。
