New constructive systems are presented in this paper. They consist in the realization of paving that remain interlaced by rugose and inclined surfaces made from the natural fissure of the concrete. This avoids the ""pumping"" and allows long life at the paving. Also, in this paper, is described lightened paving to let save concrete in a 30% and it is not necessary formworks using slide forms. The main sewers of concrete ""in situ"" made by the continuous method on the ground, is another of the applications using a system like the other one commented before. All these systems make good use of the characteristics of the matherials, with a geometry appropiated in roads, and taking account the earth pressure in the case of main sewers.
