The invention belongs to the technical field of road engineering construction, and discloses a permeable road construction method which comprises the following steps: S1, calculating the bearing capacity and the permeable rate of a road and the hole diameter and the hole spacing of permeable holes; s2, a road base layer is laid and compacted through rolling; s3, paving a permeable hole mold on the road base according to the hole spacing; s4, concrete is poured, a concrete roadbed is formed, and galling treatment is conducted on the surface of the concrete roadbed; s5, preparing pervious concrete according to the water permeability, pouring and filling each pervious hole in the concrete roadbed with the pervious concrete, and enabling the pervious concrete to form a pervious concrete layer on the concrete roadbed; and S6, a permeable asphalt layer is laid. According to the construction method, the permeable holes are additionally formed in the common concrete roadbed, the permeable concrete is poured, the common concrete roadbed is combined with the permeable concrete, the permeable physical property of the roadbed is improved, the structural strength of the roadbed is improved, and therefore the bearing capacity and the permeable rate of a road are improved.

本发明属于道路工程施工技术领域，公开了一种透水道路施工方法，包括步骤：S1、计算道路承载力、透水率以及透水孔的孔径和开孔间距；S2、铺设道路基层并碾压密实；S3、于道路基层上根据开孔间距铺设透水孔模具；S4、浇筑混凝土，形成混凝土路基，并对混凝土路基的表面进行拉毛处理；S5、根据透水率制备透水混凝土，将透水混凝土浇筑填充于混凝土路基上的每个透水孔中，并使透水混凝土在混凝土路基上形成透水混凝土层；S6、铺设透水沥青层。该施工方法通过在普通混凝土路基内增加透水孔，并浇筑透水混凝土，使普通混凝土路基与透水混凝土结合，改善了路基的透水物理性质并提高其结构强度，从而提高了道路的承载能力和透水率。
