The VSS Macropaver Expandable Microsurfacing Box is infinitely adjustable between 9 and 14 ft. The box allows a slurry seal/microsurfacing crew to apply a wide range of microsurfacings with consistency while simultaneously expanding and contracting to the desired designated widths. The unit features four 9-in. diameter augers, two per side, to enhance mixing and distribution. Extra long side strike-off plates/skids ensure optimum leveling of microsurfacing material and urethane squeegees control material thickness.
