Method for improving water permeability of pavement
The invention relates to a method for improving water permeability of a pavement.The method comprises the following steps: 1) removing a pavement surface layer; (2) performing drilling on a road base, wherein a hole channel downwards penetrates through the road base and the gravel layer in sequence and extends to the top of a plain soil layer; (3) cleaning the hole channel, laying inverted filter isolation cloth at the bottom of the hole channel, correspondingly covering opening of the hole channel with a reinforcing mesh, and fixing the reinforcing mesh; and 4) re-paving the pavement surface layer. The improvement method provided by the invention can be used for transforming a non-permeable pavement into a permeable pavement, and can also be used for repairing and improving the water permeability of an existing road pavement; and according to the paving modes of different road surfaces, the hole diameter of the drill hole, the hole channel filling treatment mode and the hole opening reinforcing measure can be selected, so that the bearing capacity of the pavement is guaranteed to the maximum extent.
本发明涉及一种路面透水性改造提高方法，包括如下步骤：1)、拆除路面面层；2)、对道路基层进行钻孔，孔道向下依次贯穿道路基层及碎石层并延伸至素土层顶部；3)、对孔道进行清理，再在孔道的底部铺设反滤隔离布，随后再在孔道的孔口处对应覆以加强网片，固定加强网片；4)、重新铺装路面面层。本发明提供的改造提高方法既可用于将非透水路面改造为透水路面，也可用于修复、提高现有道路路面的透水性；本发明中可以根据不同路面的铺装方式，选择钻孔孔径、孔道填充处理方式以及孔口补强措施，以最大限度的保证路面承载力。
