Narrow duct trenches are milled in and under asphalt in applying the trench milling method.
After having layed the speedpipe ground bundle in the duct trench under tension, the road surface is closed with the appropriate filling.
We recommend the application of this method preferably on pavements, cycle paths and roads with reduced load. So far no long-term experience is available concerning road damages and effects on speedpipe ground.
