[Scope of Claim for Utility Model Registration] The detection part is made of a cylindrical dyuracon resin base 2 filled with an acrylic adhesive and a mixture 3 of silica sand as an insulator, and a bronze electrode 1 incorporated therein. This device is buried in the road surface, and the capacitance of the road surface is measured by applying the dielectric properties of snow and ice and the principle of a capacitor, and the dielectric constant is determined.The capacitance of the road surface is measured using a capacitance meter 9. Then, the dielectric constant is determined by the calculation unit 10,
It determines whether the road surface is dry, wet, water film, snow, compacted snow, ice sheets, etc. The dielectric road surface freeze detector configured as described above.
