State-of-the-art technology for better roads Cold milling is the economical solution for road construction International traffic volumes are steadily increasing. As a result, road systems are required to cope with e ­ ver higher demands. State-of-the-art cold milling technology meets all expectations when it comes to the economically efficient and environmentally friendly rehabilitation of roads. Our inspired concept to rehabilitate damaged road pavements quickly and efficiently with the innovative milling p ­ rocess heralded the era of the cold milling technology. Since that time, Wirtgen...

Wirtgen offers innovative methods for fast, environmentally gentle rehabilitation of heavily trafficked roads Wirtgen is setting the pace in road rehabilitation Cold milling machines remove the damaged layers prior to placing the new pavement The cold milling technology has gained acceptance worldwide, and is unrivalled when it comes to economic efficiency and environmental friendliness. Being valuable recycling material, the reclaimed asphalt pavement is normally fully reused in recycling plants or asphalt mixing plants. The machines are capable of removing entire pavement packages at full...

Small milling machines: Successful in most diverse applications The pavement around manhole covers is milled off quickly and precisely in one single pass Small milling machines are the right choice for workshop floors or parking decks Leaning into the bend with small milling machines Not only large-scale construction projects but in particular smaller rehabilitation measures play a vital role in the structural maintenance of our road network. Small milling machines are the ideal candidates for this type of job. Their compact design and extremely small milling radius enable them to work with...

Efficient milling of medium-sized surfaces is part of the small machines’ repertoire Milling with economic efficiency on small job sites Effective fine milling operations like placing or removing road markings Our small milling machines offer working widths between 35 cm and 1.30 m for the removal of road pavements. Large milling machines – the specialists when it comes to removing surfaces on a large scale – and small milling machines are a perfect team. Milling around obstacles like manhole covers, hydrants or kerbs, or working in tight bends poses no problem at all for our small...

Large milling machines: Maximum power for large surfaces Powerful large milling machines meet all requirements for the fast completion of construction projects Removing asphalt packages at depths of up to 35 cm High daily production rates guaranteed Large milling machines offer decisive advantages when it comes to large-scale rehabilitation projects: Superior area performance, fast completion of construction projects and minimum disruptions to traffic are all marks in favour of the use of these high-performance machines. Their central field of application is the removal of road pavements at...

In full control on large job sites Fine milling enables pavement irregularities to be levelled without the need for new asphalt mix Under ideal conditions, the largest cold milling machine model – the W 250 – is capable of removing up to 1,200 tonnes per hour of asphalt material, equalling the loading capacity of 60 trucks. Our high-performance machines master their job thanks to high engine power and a highly efficient mechanical milling drum drive. The loading systems are tailored to high production rates and permit flexible adaptation to conditions on the job site. Large milling machines...

From contractor with self-built hot milling machines … 1973: The hot milling machine SF 2500 is equipped with large gas tanks 1975: The hot milling machine SF 3750 specializes in the standard motorway lane width of 3.75 m 1971: The prototype of a hot milling machine is milling off damaged asphalt layers 1976: The contracting fleet of Wirtgen hot milling machines lined up in a row How cold milling became state-of-the-art technology The powerful, technically mature cold milling machines of today need some two minutes to fill a 30-ton truck with granulated asphalt material. They have come a...

Wirtgen paved the way for cold milling 1978: The 3800 C from the first generation of cold milling machines is a hydraulically driven rear loader 1980: Like all small milling machines of the first generation, the 500 C mills up to 100 mm deep 1979: Large milling machine 2200 C on three crawler tracks 1971: Wirtgen builds the first in a total number of 100 hot milling machines for their own contracting fleet. 1978: The technological leap from hot milling to cold milling is sparked by the use of carbide metal tools that are normally used in the mining industry. From 1980: The 500 C, 1200 C and...
