Patent number: 10385524Abstract: A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.Type: GrantFiled: November 22, 2016Date of Patent: August 20, 2019Assignee: DellCron Innovation ABInventors: Conny Gustavsson, Hasse Hultman
