To provide a shock-absorbing floor material that has excellent load-bearing capacity while also having an absorption effect due to its soft layer.SOLUTION: A shock-absorbing flooring material comprises a floor raising material, a floor base material formed with soft material that is provided below the floor raising material, and an intermediate material that is provided between the floor raising material and the floor base material. The floor base material has an Asker C hardness of 20 or more and 60 or less, and a thickness of 4 mm or more and 15 mm or less. The intermediate material has a thickness of 2 mm or more and 8 mm or less, and a strain (ε(σmax)) of 0.5% or more, where the maximum bending strength is obtained in a three-point bending test according to JIS K7074, and a bending elasticity modulus of 1 GPa or more and 15 GPa or less.SELECTED DRAWING: Figure 1
【課題】軟質層による吸収効果をもちながらも、耐荷重性に優れた衝撃吸収床材を提供する。【解決手段】衝撃吸収床材は、床上材と、床上材の下方に設けられ、軟質材料で形成された床下地材と、床上材と床下地材との間に設けられた中間材と、を備え、床下地材は、アスカーＣ硬度が２０以上６０以下、かつ厚みが４ｍｍ以上１５ｍｍ以下であり、中間材は、厚みが２ｍｍ以上８ｍｍ以下、ＪＩＳ Ｋ７０７４による３点曲げ試験において曲げ強度が最大になる歪み（ε（σｍａｘ）)が０．５％以上、かつ曲げ弾性率が１ＧＰa以上１５ＧＰa以下となっている。【選択図】図１
