Today’s technologically advanced cold milling machines can load a 30-ton truck with asphalt granulate within a few minutes. The road to this point was a long one, however – WIRTGEN has always been instrumental in driving progress in this field. WIRTGEN built the first of a total of 100 hot milling machines for its own service fleet in 1971. The idea to use the round shank bits used in mining with carbide tips made the technological transition from hot milling to cold milling possible in 1979.
From the first building block – the development of cold milling technology for road construction – to the present day, WIRTGEN has reached numerous innovative milestones along the road to this technology’s success. Today, the name WIRTGEN is synonymous with high-performance cold milling technology throughout the world.
