Abstract (en)

[origin: EP1840267A2] The device has an agitator (2) for a cement grout arranged on a timber elevator type engine (3) for permitting final mixing of the grout with a water quantity and flux on installation place of the device. An applicator (5) is connected to a trailer (4) for injecting the grout in porous bituminous road surfaces (6) in which injection pressure of the grout is built up by a level (11) of the grout stored in an upper part of the applicator above the surface. The applicator is connected to the agitator by a pipe (21) tiltable with respect to elevation of the agitator by the engine. An independent claim is also included for a method for injecting cement grout in porous road surfaces.
