## Abstract

A noise reducing roadway includes pipe-shaped bodies having a fitting groove formed toward an inside of one end, a shim protruding outward from the other end and a communication portion formed at a side portion of the body to allow the hollow interior to communicate with the outside environment. A heating wire is provided to prevent ice from filling the pipe-shaped bodies.

## Claims

### Claim 1

An apparatus for reducing road noise, the apparatus being seated on a plurality of buried grooves spaced at regular intervals and in a direction in which vehicles travel on a road surface, the apparatus comprising:
pipe-shaped bodies each having a hollow formed in the corresponding body to pass through a part of one end and a part of the other end of the body, a fitting groove formed toward an inside of the one end, a shim protruding outward from the other end, and a communication portion formed at a side portion of the body to allow the hollow to communicate with the outside, the communication portion comprising a cylindrical shape having a diameter ranging from 4 mm to 10 mm, wherein distal ends of the communication portions open to an outside comprise filtration films, and wherein the distal ends of the communication portions are positioned 2 mm to 3 mm lower than the road surface;
wherein the plurality of bodies are connected to each other such that the shim is fastened to the corresponding fitting groove, and wherein an interval between the communication portions, which are configured by connecting the plurality of bodies to each other, is 40+/−10 mm;
wherein a space between the buried grooves and the apparatus for reducing road noise comprises a filler material adapted to reduce road noise, and wherein the communication portions are not filled with filler material, and
wherein a heating wire is provided inside and/or outside the body.

### Claim 2 (depends on 1)

A method of installing an apparatus for reducing road noise, the method comprising:
a buried groove forming step of forming a plurality of buried grooves in a direction in which vehicles travel on a road surface at regular intervals;
an arranging step of seating the apparatus of claim 1 on the buried grooves such that distal ends of the communication portions are lower than the road surface, and seating the plurality of bodies on the buried grooves, respectively, while connecting the bodies to each other;
an injecting step of inserting fillers into the buried grooves of the arranging step so that the apparatuses for reducing road noise are buried in the buried grooves; and
a hardening step of hardening the fillers, wherein an interval between the plurality of buried grooves is formed such that an interval between the closest communication portions is 40±10 mm when the apparatuses for reducing road noise are seated on the plurality of buried grooves, respectively, and wherein the distal ends of the communication portions are located to be lower than the road surface by 2 mm to 3 mm.
