Mobile road surface treatment system

A mobile road surface treatment system, comprising:

• a material extrusion module connected to a material preparation unit on a gantry comprising at least an X-axis member and a Y-axis member, wherein the material extrusion module is configured to move along the X-axis member and Y-axis member,
• a scanner module configured to detect a road cavity, and
• a control module on a vehicle having a moving speed and moving direction
• wherein
• the scanner module generates a geometric code for the road cavity,
• the controller instructs the material extrusion module based on the geometric code to direct the material extrusion module to move along the X-axis member and Y-axis member and remain in a position above the road cavity,
• the material extrusion module deposits a repair material from the material preparation unit while the extrusion module hovers in the position.

A method for maintaining road surface on a moving vehicle, comprising:

• providing a vehicle with a scanner module, a control module, and a material extrusion module mounted on a gantry,
• driving the vehicle to travel at a moving speed and a moving direction,
• detecting a road cavity with the scanner module and generating a geometric code,
• generating an instruction with the control module based on the geometric code, the moving speed, and the moving direction,
• directing, with the instruction, the material extrusion module to move along the gantry, such that the material extrusion remains in a position above the road cavity,
• and depositing a repair material through the material extrusion module while the extrusion module hovers in the position.
