<p>The apparatus for constructing, in a single pass, a ready-to-use road pavement (63) comprises, from front to rear: a directing and rolling transverse roller (1); two driving lateral wheels (2) arranged in proximity to the centre of the subframe (3); in immediate proximity to these wheels (2), a device (4) for dispensing the aggregate-binder mixture; a transverse smoothing blade (5) having an alternating axial translational movement; a rammer (6) controlled by rotary cams; and a transverse heating ramp (7) for the hardening of a polymerisable binder. The dispensing device (4) comprises a hopper, which is centred on the transverse plane containing the axis of the wheels (2) and is equipped with a central vertical thrust screw (23) which supplies a transverse housing (28) having a pouring spout (33) at a controlled rate, a transverse rotary porcupine roller in the form of two truncated cones with their large bases opposite and having semi-rigid strands being accommodated in this housing (28). <IMAGE></p> |
