ENVIRONMENT: BARRIERS TEST

AMBIENTE: BARRIERE ALLA PROVA

A VERTICAL BARRIER HAS BEEN DESIGNED WHICH, BECAUSE OF ITS SPECIAL ABILITY TO ABSORB SOUND, IS PARTICULARLY SUITABLE FOR USE AS AN ANTI-NOISE BARRIER. THE BARRIER IS MADE OF PREFABRICATED CONCRETE. IT SHOULD BE NOTED THAT THE GOOD VALUES REPORTED IN THIS ARTICLE WERE OBTAINED FROM TYPE 24 ELEMENTS WITH THE DIMENSIONS 90X40X60CM, AND FILL MATERIAL FROM SUPERFICIAL EXCAVATION, WITHOUT ANY VEGETATION. THE VOLUMES WILL BE HIGHER IF TYPE 20 ELEMENTS OF A DOUBLE THICKNESS ARE EMPLOYED, (90X40X120CM), AND WHEN VEGETATION HAS EVENTUALLY COVERED THE WHOLE BARRIER.
