Mature, state-of-the-art technology for better roads International traffic volumes are steadily increasing. As a result, road systems are required to cope with ever 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 process heralded the era of the cold milling technology. Since that time, Wirtgen has been considered the world market leader in this...

4 // 5 The cold milling technology has gained acceptance worldwide, and is unrivalled when it comes to economic efficiency and environmental friendliness. The machines are capable of removing entire pavement packages at full depth, as well as individual, thin pavement layers. Being valuable recycling material, the reclaimed asphalt pavement is normally fully reused in asphalt mixing plants. Being a fast-paced construction method, cold recycling is cost-effective and minimizes disruptions to traffic. Wirtgen is setting the pace in road rehabilitation Wirtgen offers innovative methods for...

Small milling machines: Recipe for success when space is limited 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 maximum precision even in extremely confined conditions. Small milling machines can additionally be equipped with a detachable loading conveyor. These highly manoeuvrable machines play their many economical advantages...

6 // 7 Our small milling machines offer working widths between 35 cm and 1.30 m for the removal of road pavements. Milling around obstacles like manhole covers, hydrants or kerbs, or working in tight bends poses no problem at all for our small machines. Large milling machines – the specialists when it comes to removing surfaces on a large scale – and small milling machines are a perfect team. Compact overall dimensions and low operating weights facilitate both machine transport and indoor operations. Milling with economic efficiency on small job sites Efficient milling of medium-sized...

Large milling machines: Maximum power for large surfaces High daily production rates guaranteed Powerful large milling machines meet all requirements for the fast completion of construction projects Removing asphalt packages at depths of up to 35 cm 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...

8 // 9 Under optimum conditions, our largest cold milling machine – the W 2200 – is capable of removing in excess of 1,200 tons of asphalt material per hour, equalling the 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 offer standard working widths between 1.00 m and 4.40 m for the removal of road pavements. In full control on large job sites Fine...

From contractor with self-built hot milling machines … 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 long way – and Wirtgen has played a vital role in their breath-taking development. From the first cornerstone – development of the cold milling technology for road construction – to date, we have paved the road to success of this technology with numerous, innovative milestones. Today, the name Wirtgen is distinctively and inextricably tied to tried-andtested cold milling...

10 // 11 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 1900 C models are the first cold milling machines successfully launched in the market. 1984: The 2000 VC – the first cold milling machine with front-loading conveyor – leaves the factory gates, making a deep and lasting impact on job site logistics. Wirtgen paved the way for cold milling...
