Road equipped with road safety barriers fixed to the ground and installation method thereof

A road with a stabilized road substrate (201) consisting of a ground with known compactness characteristics on which a road surface (210) is spread, and equipped with a safety road barrier comprising a plurality of uprights (110), fixed in the edge of the road as in the known art, and wherein said safety barrier comprises at least the elements:

• a. a system of vertical plates (153), with a thin section, infixed on said road substrate (201) below said road surface (210);
• b. a junction element (151) arranged to be coupled to an upright (110) of a road safety barrier by wrapping them around its base;
• c. a connecting tie rod (152) lying, or slightly buried, on the road substrate (201), which is:
• i. coupled to said system of vertical plates (153) at one of its ends, and
• ii. releasably coupled to said junction element (151) at its other end;
• and said junction element (151) comprises parts with programmed breakage;
• and said programmed breakage is designed to happen when the following conditions occur:
• said connecting tie rod (152) exerts a traction force on said junction element (151) higher than a predetermined threshold, and
• said connecting tie rod (152) exerts a traction force on said junction element (151) lower than the force that would damage said connecting tie rod (152) or to the force that would cause a displacement of said system of vertical plates (153) with respect to the road substrate in which it is infixed.
