Abstract
The invention relates to road safety barriers, especially for highways, and of the kind comprising a plurality of modules coupled to each other by at least one linear element which may be under mechanical tension, the modules being composed of a material capable of bursting under an internal tension due to the linear elements which pass through the modules and are embedded in the mass of the modules, whereby the module struck by a vehicle out of control bursts, possibly together with the neighboring modules. The assembly of modules and linear elements is not fixed on the ground but is free to slide laterally under the impact of a vehicle. The constituent material of the modules may comprise a mixture of a synthetic or natural plastic material and a binder consisting of cement, mortar or plaster, and the linear elements may be formed by steel cables or ropes, or chains of links, the links being formed from the metal reinforcing belts of pneumatic tires. The invention also covers a method of manufacture of the safety barrier on the site of its actual installation.
