To provide a road structure that prevents the occurrence of a problem caused by temperature rise of a heating element when the heating element is buried and installed in a road formed using concrete.SOLUTION: A precast concrete slab 6 comprises lattice frame-shaped reinforcing bars 8, a box-shaped and steel LED box 10 formed to fit into the lattice frame of the reinforcing bars 8, and an LED unit 12 accommodated in contact with the LED box 10, and is formed by pouring of concrete 18. Heat generated by the LED unit 12 is transmitted to the reinforcing bars 8 via the LED box 10, and is released to the concrete 18 from the LED box 10 and the reinforcing bars 8.SELECTED DRAWING: Figure 3 【課題】コンクリートを用いて形成される道路に発熱体を埋設して設置する場合、発熱体の温度上昇に伴う不具合の発生を防止する。【解決手段】プレキャストコンクリート版６は、格子枠状の鉄筋８と、鉄筋８の格子枠に嵌まるよう形成される箱形状で鉄鋼製のＬＥＤ用ボックス１０と、ＬＥＤ用ボックス１０に当接させて収容されるＬＥＤユニット１２と、備え、コンクリート１８が流し込まれて形成される。ＬＥＤユニット１２が発する熱は、ＬＥＤ用ボックス１０を介して鉄筋８に伝わり、ＬＥＤ用ボックス１０及び鉄筋８からコンクリート１８に逃がされる。【選択図】図３
