摘要： A machine lays a bituminous carpet for closing microtrenches. The machine includes a truck having a drive system, which defines a footprint area on a surface whereon the truck can move, and a preparing device for preparing bitumen for laying. The preparing device includes a bitumen container having an inlet into which bitumen in introduced, an outlet through which the bitumen prepared for laying exits, a heating system for raising the temperature of the bitumen introduced into the preparing device. A laying device receives the bitumen prepared for laying and lays the bitumen in carpet form. The laying device includes a forming element for shaping and laying bitumen as a carpet over a laying area; a drain channel, between the outlet of the preparing device and the forming element, conducting bitumen towards the forming element. The preparing device includes a mixing device mixing the bitumen while preparing it for laying.
