Fast and gentle!
In a single step, a special milling machine is used to cut a narrow slit trench 18 to 25 cm wide and 50 to 70 cm deep in the road shoulder approx. 10 cm from the edge of the asphalt. In the process, up to 5 pipe joints are inserted into the trench and encased in screened, suitable fine material. A coded route warning tape is inserted at the desired height and the trench is filled with the remaining removed and prepared material. During the entire laying process, the trench remains protected by an integrated travelling formwork device and thus the road body remains stable. This is followed by specially developed, multi-layer compaction and, finally, automated restoration of the road shoulder. An integrated satellite receiver simultaneously provides precise position documentation with an accuracy of 2 to 5 cm. Lateral displacement of the laying unit minimises edge loads on the asphalt pavement. LAYJET technology is considered by experts to be by far the most gentle laying method along roads in the road shoulder, as the road body remains stable during the entire laying process and its homogeneity is hardly disturbed.
