(57) A road crash barrier (1) is described and comprises a plurality of posts (3) which can be anchored to the roadway structure (2) by means of coach bolts (21) in a manner such as to be translatable under stress in order to absorb the energy of an impact of a vehicle by deformation and/or breakage of the coach bolts (21), in which a shock-absorber (20) is interposed between each post (3) and the respective coach bolt (21) and comprises an element which is fixed firmly to the post (3) and in which a slot (25), elongate in the direction of translation of the barrier (1), is formed; the coach bolt (21) extends through the slot (25) in order to clamp the shock-absorber element against a sliding surface (15) of the post (3) with a predetermined load.
