Abstract
A safety barrier for roads, used as a traffic divider, includes a double row of concrete made New Jersey barrier elements which allow the realization of a hedge on earth interposed between the barrier elements. The earth is contained in a sack made of nonwoven fabric, fixed, to both barrier elements, so as to leave gaps behind the rear walls of the barrier elements. The gaps together with a plurality of sliders or runners provided on the barrier's base, allow during impact a controlled displacement of the barrier elements. The calibration of decelerations is adjusted by the material used for the sliders.
