The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for adding line features to a roadway surface. In some examples, the line features may include wires, conduits and electronic components. In some examples, the mobile additive manufacturing apparatus may create communication means into an advanced roadway in line features, which may be used for various communications including communications to and from autonomous vehicles. The communications may involve data related to the operation of systems of autonomous vehicles. In other examples, the line features may be dynamically colored with LED components.

An example method includes storing surface treatment data to specify at least one selected surface treatment to apply at a target location along a vehicle path of travel, the surface treatment data including a machine-readable description and a reference coordinate frame for the selected surface treatment. The method also includes generating task plan data to apply the selected surface treatment based on the surface treatment data and at least one parameter of an application tool. The method also includes determining a location and orientation of the application tool with respect to the vehicle path of travel based on location data representing a current location of a vehicle carrying the application tool. The method also includes computing a joint-space trajectory to enable the application tool to apply the selected surface treatment at the target location based on the task plan data and the determined location of the application tool.

A method of marking a line includes providing a line marking apparatus including a body (21), a line marking head (29) movable relative to the body, and a positioning system (35, 37, 41, 43) for determining a geographical location of the line marking head. In addition, a mathematical model is provided for a line to be marked by the line marking head, the model being cumulatively updated in response to a position fix (61) obtained by the positioning system. The position of the line marking head is adjusted relative to the body in dependence upon the mathematical model.

A surface marking devices for heating and applying thermoplastic material. The surface marking device is comprised of laterally disposed oil-jacketed melting kettles having a rotatable auger extending from a first end to a second end; the first end having an open inlet for receipt of particulate thermoplastic marking material in a non-molten state. The second end coupled to a thermo pump for transfer of the thermoplastic marking material in a molten state to a sprayer, extrusion die, or an auxiliary vehicle for subsequent application. Retro-reflective glass beads can be added to the molten state during the spraying step.

A wheel part includes: a body having an axis; an annular outer surface through which the axis extends centrally and defining a socket; a stamp mounted in the socket for movement between an extended position wherein the stamp projects radially beyond the surface and a retracted position wherein the stamp terminates radially inwardly beneath the surface; and a bias mechanism adapted to bias the stamp for movement to the extended position. A manually grippable handpiece is adapted to releasably receive the body for rotatable movement about the axis and is adapted such that at least a portion of the surface projects beyond the housing. An inker is mounted to the handpiece in spaced relation to the surface such that, on rotation of the wheel, the stamp engages the inker and receives ink therefrom, whereby, when the body is roiled along a workpiece, the workpiece is demarcated at uniform intervals.

A pavement striping devices for heating and applying thermoplastic material to a road surface is provided. The pavement striping device includes of: a hopper for holding a supply of particulate thermoplastic marking material in a non-molten state, an air or oil-heat transfer medium melting kettle having a series of coaxial conveyored or unconveyored conduits within, a plastic extruder for transporting the thermoplastic particulate from the hopper to the series of coaxial conveyored or unconveyored conduits with the air or oil-heat transfer medium melting kettle, a heating mechanism for heating the air or oil-heat transfer medium melting kettle and the plastic extruder to a temperature suitable for melting thermoplastic, and a means for driving the stream of molten thermoplastic through the series of coaxial conveyored or unconveyored conduits to a sprayer or extrusion die, all of which form a means by which the molten thermoplastic is directed to the pavement surface.

A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).
