Adjustable paving machine

An adjustable paving machine, comprising:

• a first frame portion including a first plurality of walls;
• a variably expandable portion including a second plurality of operably coupled to the first frame portion and configured to be laterally movable relative to the first frame portion;
• at least one spreading affixed to at least one of the first frame portion or the variably expandable portion and configured to spread a paving material on a paving surface;
• and
• an actuator coupled to the movable frame and configured to move the variably expandable portion relative to the first frame portion,
• wherein:
• the actuator comprises:
• a rotary actuator;
• a first rotating guide member coupled to the rotary actuator;
• and
• a second rotating guide member in rotational contact with the first rotating guide member and coupled to a first linear actuator;
• the rotary actuator is configured to transmit rotational motion to the first linear actuator via the first and second rotating guide members;
• and
• the first linear actuator is operatively coupled to a first thrust member coupled to the first frame portion.

A paving machine, comprising:

• a plurality of walls forming a rectangular containment basin configured to receive and confine a paving material during towing by a separate vehicle;
• and
• a plurality of brushes arranged into a plurality of rows within the rectangular containment basin, the plurality of rows being configured to sequentially pass over and spread the paving material on a paving surface during a paving event,
• wherein a first row of the plurality of rows that first passes over the paving material discharged inside of the containment basin has a V-shape with a central vertex that that leads opposing ends.
