A machine for placing at least one duct/communication cable below a road surface in an area, said area comprising a first layer and a second layer, said first layer being a road layer, such as asphalt or concrete, and said second layer being a bearing layer for said first layer and being located below said first layer;
- said machine comprising:
- a saw blade arranged to saw a micro trench in said area through said first layer into said second layer, wherein said micro trench has a depth d;
- and
- a stabilizing device positioned immediately behind said saw blade and being arranged to place a plurality of ducts/communication cables in said micro trench by means of guiding means comprised in said stabilizing device so that said plurality of ducts/communication cables are placed below said first layer;
- wherein said machine is arranged to continuously adjust the depth d while in operation.
