Methods and apparatus for mobile additive manufacturing of advanced structures and roadways

A method for forming and repairing a roadway comprising:

• transmitting a control signal to an apparatus, wherein the apparatus is a mobile additive manufacturing apparatus comprising:
• a drive system operative to move the apparatus along a surface,
• a navigation system to determine location,
• a controller capable of executing algorithms and providing control signals,
• a vision system capable of scanning the surface and measuring a topography of the surface;
• an additive manufacturing system to deposit at least a first material in a prescribed location on the surface according to a digital model processed by the controller wherein the additive manufacturing system that deposits the first material comprises:
• a heated extrusion head which heats an extrusion material to a molten or semi-molten form,
• the extrusion material formed into a filament, and
• a feeding apparatus which feeds the filament into the heated extrusion head and extrudes the melted material to the prescribed location on a roadway, and
• a power system capable of providing power to operate at least the drive system, navigation system, controller and additive manufacturing system;
• forming a first deposit of a first material on the surface;
• moving the apparatus to a different location;
• and
• forming a second deposit of the first material on the different location.
