Abstract:
Provided is an air-blowing-type road surface snow-melting system which makes it possible to reduce the height of a hollow roadbed body while also making the amount of air blown out from an air-permeable structure substantially uniform. An air-blowing-type road surface snow-melting system (1) comprises: a hollow roadbed body (2) which is provided with a hollow section (21) and is buried beneath a road surface; an air-permeable structure (3) which is disposed on the hollow roadbed body (2) to form the road surface; and a vent pipe (4) which is laid inside the hollow section (21) of the hollow roadbed body (2), wherein the vent pipe (4) is laid in the shape of a loop so as to enclose a predetermined snow-melting area and in addition a plurality of blow-out sections (42) which open toward the inside of the loop are disposed in the vent pipe (4).
