Abstract: A paver assembly includes a paving unit assembly having a first side wall, a second side wall, and an expandable frame connecting the first side wall and the second side wall together. The expandable frame can move the first side wall and the second side wall towards and away from one another to contract and expand the paving unit assembly so that a width of the paving unit assembly can be the same as a width of a surface paved by the paver assembly. The paver assembly can also include a first paving unit fixedly connected with respect to the first side wall and a second paving unit fixedly connected with respect to the second side wall, where the first paving unit and the second paving unit are offset with respect to one another and move past one another as the paver assembly expands and contracts.
