Abstract (en)
The invention provides a road working vehicle (10) such as a skid steer vehicle or small excavator having attached thereto, preferably in place of the bucket of the excavator a road working head (30) comprising a compaction roller (44) which is adapted to roll on the road material to be compacted, for example in a trench, and the head is adapted to castor about an upright axis (42) so that the roller can automatically follow any wavyness in the sides of the trench in which the roller operates. Preferably the roller is of substantial diameter e.g. in the order of 1500 mm, and is made up of a plurality of sections so that sections can be removed when the roller is required to operate in a narrower trench. There may also be a vibrator for vibrating the roller as it works.
