PURPOSE:To prevent the cracking on the road surface by burying a radiating pipe in the road surface and a heating pipe in the road floor to melt snow with hot water, storing heat with hot water when the road floor is at the freezing pint or below, and switching the radiating pipe and heating pipe according to the temperature. CONSTITUTION:A radiating pipe 7 and a road surface temperature detector 9 connected to a snowfall detector 8 are buried in the road surface made of a paving material 1, a roadbed 2 made of a granular material below it is provided in contact with the road floor 3 below, and a heating pipe 4 and a road floor temperature detector 6 connected to the snowfall detector 8 are installed on the boundary face or in the road floor 3. The detector 8 is connected to an automatic action panel 5, which switches a flow control valve 10 and operates a pump. When the road surface is cooled to 0 deg.C, the detector 8 detects it and directly sends a signal to the automatic action panel 5, the control valve 10 is switched, and hot water is fed to the heating pipe 4. The road floor 3 is warmed, heat is stored, and the freezing of the road floor 3 can be prevented.
