摘要

Soundproof coating for roads of terrestrial circulation, that cover at least the area of the footwear and that constituted by a carrier construction as well as by covering elements fixed in this, which form partly a closed area and, on the other hand, a zone open, are the elements of covering the open area in the form of laminillas, characterized because the closed area is on all the footwear (4) forming a wrap (2), because the open area is set in a marginal area next to the footwear (4), and because the coating elements (2 '' '', 2 '' '' d) are available in this area so that all the sound waves (5) that are produced in the area of the footwear (4) can not leave up without diffraction or reflection.
