<p>One or more curbs (1) made of hard rubber, can be applied longitudinally in the contoured casing (2) and also in barriers of normal production. Said curbs make it possible to absorb the force of shock, by avoiding the direct impact between the metal parts of the motor vehicle and the barriers, which are made of steel band or of concrete. Said curbs can also be made of rubber or of a similar material whose mixture contains elements suitable for conferring on it an effect of fluorescence.</p> |
