Overview
VDA MAX series pavers, manufactured in Brazil, are engineered for asphalt paving operations with a focus on serviceability, efficient material flow and accurate laying. The machine features a redesigned material conveyor system for increased durability and simplified maintenance, plus a laterally movable operator station and sliding seat for improved visibility.

Tyre paver VDA 421 MAX
The VDA 421 MAX is a tyre paver optimized for road paving, slope work and application of granular base layers. It uses belts with trapezoidal solid rubber shoes for extended wear life, a compact turning radius for maneuverability and a hydrostatic transmission paired with motors and gearboxes coupled to the sprockets for consistent material feed.

Features
