The process comprises making a series of longitudinal holes (6) within the mass of concrete (4) which forms the paving, with the cooperation of a slip-form, associated with any conventional concrete spreader, and embodied by a series of tubes (1) having their front end (2) closed and their rear end (3) open. In order to avoid the deformation of the longitudinal holes (6) during the initial phase of the concrete setting, a pressure fluid is introduced into said holes, said fluid closing the pores of the concrete on the one hand and acting as a physical support for the concrete on the other hand, the fluid accessing to said holes (6) through the tubes (1) and supply conduits (5) associated to said tubes. This process is intended to achieve a better distribution of the concrete and therefore to save said material. |
