Experimental investigation on the flexural behavior of pervious concrete beams reinforced with geogrids

•Mechanical properties of pervious concrete reinforced with geogrids are studies.•Geogrids restrain the generation and propagation of the crack of pervious concrete.•Reinforced beams have brilliant post-cracking performance.•Embedding the geogrids at both 1/3 depth and 2/3 depth of the thickness works best.
