Drainage asphalt pavement construction process
The invention discloses a drainage asphalt pavement construction process, and relates to the technical field of expressway pavement construction, and the drainage asphalt pavement construction process comprises the following steps: S1, performing roadbed construction: removing sundries on the surface of a road, and bulldozing and compacting plain soil on the pavement until the compaction degree is greater than 92%; S2, constructing a waterproof layer, paving waterproof geotechnical cloth on the surface of the roadbed with the laying thickness of 15-18 mm; S3, performing construction of an inverted filter layer; S4, performing porous cement base layer construction; S5, laying a drainage asphalt layer; S6, carrying out compacting; S7, carrying out road surface detection; and S8, performing traffic opening: opening traffic and implementing operation after various indexes of road surface detection are qualified. The drainage asphalt layer comprises the upper surface layer and the lower surface layer, the upper surface layer is the PAC-13 drainage asphalt layer, and the lower surface layer is the PAC-20 drainage asphalt layer, so that the water seepage performance of the pavement is further improved, water accumulation on the pavement is avoided, and the driving visibility and safety in rainy days are improved.
本发明公开了一种排水沥青路面施工工艺，涉及高速路面施工技术领域，包括如下步骤：S1，路基施工，清除路表杂物，推平压实路面素土，压实度大于92％；S2，防水层施工，在路基的表面铺设防水土工布，铺设厚度为15‑18mm；S3，反滤层施工；S4，多孔水泥基层施工；S5，排水沥青层铺设；S6，压实；S7，路面检测；S8，交通开放：待路面检测各项指标合格后，开放交通，施行运营。本发明通过将排水沥青层设置为上面层和下面层，并且上面层为PAC‑13排水沥青层，下面层为PAC‑20排水沥青层，进一步加大路面渗水性能，避免路面积水，提高雨天行车能见度和安全性。
