Abstract (en)

[origin: WO8702398A1] Machine (10) for treating a road surface (15) and in particular, but not exclusively, to a machine (10) for forming lateral grooves in such surfaces (15). The machine (10) essentially comprises a wheeled main frame (11) on which are mounted two lateral wheeled sub-frames (12) which carry grooving treatment heads (13). The treatment heads (13) can be lifted to allow the machine (10) to be moved in a longitudinal direction (17) subsequently lowered onto the wheels (14) of the sub-frames (12) for lateral grooving movement (18).
