Abstract (en)
A process of manufacturing "in situ" of safety barriers for roads and highways, forming these barriers separating members for opposite traffic ways. The process is based in filling a mould with a suitable material whose density is similar to that for concrete, so to get blocks that, near-by disposed, form the barrier on the road. The moulds are placed in the final location to be filled later directly from a concrete-mixer truck and to have so the barrier without handling the blocks. The mould can be made of any suitable material (polyester, steel sheet, rigid plastics,....) and will have a higher filler mouth and holes for air exit, as well as lower projections that form legs, so that the barrier that has to be made, remains sligtly separated from the ground and allows the flow of the water under the mould.
