PROBLEM TO BE SOLVED: To provide a construction method of a road surface snow melting structure that suppresses manufacturing costs and prevents damaging of a buried pipe.SOLUTION: A construction method of a road surface snow melting structure of the present invention includes at least: a first step in which a resin tube 10 is laid on a foundation in the construction method of the road surface snow melting structure that melts snow using heat of a liquid flowing in a pipe; a second step in which a refrigerant 30 is made to flow through the resin pipe; a third step in which an asphalt mixture 40 is laid and leveled until the resin pipe is buried, and then an asphalt pavement body 50 is formed by roller compaction of the asphalt mixture; and a step 4 in which a semi-flexible pavement is formed by having cement milk 80 penetrate into the asphalt pavement body. The construction method of the present invention provides a firm pavement body even when a resin tube is used, allowing a resin body to be placed near the road surface. The method also eliminates demerits of the resin tube including low heat conductivity and a possibility of significant deformation caused by a large load.SELECTED DRAWING: Figure 1 |
