Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a water permeable and holding material using a concrete fragment as an segregate, which is used for forming a road bed material for concrete pavement having water permeability together with water holding property by using a concrete fragment, and to provide a production method therefor. SOLUTION: A raw material having a composition consisting of 10-30% Portland cement and 5-20% blast furnace slag or a fly ash powder is mixed with 50-80% (by weight) aggregate obtained by crushing the concrete fragment and adjusting the sizes of the crushed fragment so as to be 20±5% in
