Exposed aggregate pervious concrete pavement and construction process thereof
The invention discloses an exposed aggregate pervious concrete pavement and a construction process thereof. The exposed aggregate pervious concrete pavement comprises a bottom graded broken stone hardcore layer with the thickness of 200mm, a sand filter layer, a strength C25 pervious concrete layer, a strength C25 exposed aggregate pervious concrete layer and a top sprayed dipropylene polyurethane colorless transparent layer, wherein the sand filter layer, the strength C25 pervious concrete layer and the strength C25 exposed aggregate pervious concrete layer are sequentially arranged above the bottom graded broken stone hardcore layer; the sand filter layer is a medium-coarse sand filter layer and comprises medium gravel and coarse gravel with the weight ratio of 1: (0.2-2), the particle size of the medium gravel is 0.25-0.5 mm, and the particle size of the coarse gravel is 0.5-2 mm; the material particle size of the strength C25 pervious concrete layer is 10 +/-2mm, and the material particle size of the strength C25 exposed aggregate pervious concrete layer is 5-8mm. The concrete layers with different particle sizes are matched to form a unique pore structure, so that the permeable rate of the exposed permeable concrete pavement is improved, the permeable rate can reach 32-52 L/m < 2 >/h, and the problems of drainage caused by rainfall, slippery and water splashing caused by urban road water accumulation and light reflection caused by night vehicle light can be easily relieved.
本发明公开了一种露骨料透水混凝土路面及其施工工艺，包括底层的200mm厚级配碎石垫层，在其上方依次设置有砂滤层、强度C25透水混凝土层、强度C25露骨料透水混凝土层，顶层喷涂双丙聚氨酯无色透明层；所述砂滤层为中、粗砂滤层，其中包括重量比在1：(0.2‑2)的中砂砾与粗砂砾，所述中砂砾的粒径尺寸在0.25‑0.5mm、粗砂砾的粒径尺寸在0.5‑2mm；所述强度C25透水混凝土层的物料粒径尺寸在10±2mm，所述强度C25露骨料透水混凝土层的物料粒径尺寸在5‑8mm。通过多层不同粒径尺寸的混凝土层搭配，形成独特的孔隙结构，提高露骨透水混凝土路面的透水率，透水率能达到32‑52升/平方米/小时，能够轻松缓解降雨的排水、城市道路积水所产生的湿滑、溅水和夜间车辆灯光产生的反光问题。
