From an idea to breakthrough technology

Hot recycling gains acceptance

In the mid-1970s, WIRTGEN developed a method for the economically efficient rehabilitation of damaged bituminous road surfaces. Based on the revolutionary idea to replasticize roads by means of heat, the first hot recycler was developed in 1976. That was the beginning of WIRTGEN’s success as a recycling contractor, operating their own fleet of hot recyclers. WIRTGEN perfected the “heated” process with much passion and pioneering spirit, and ever-new, successful inspirations marked the path of this innovative technology. The equation set up back then is working out just right today, when economically efficient and environmentally friendly construction methods are called for.

The first Repaver rolled off the assembly line in 1976, leading Wirtgen’s future contracting fleet of hot recyclers. The development of the Remix process in 1979 represented a quantum leap in the quality of hot recycled asphalt road surfaces.

Market-leading and cutting-edge products for the Road and Mineral Technologies business sectors are constructed at the WIRTGEN brand headquarters in Windhagen, Rhineland-Palatinate. With its innovative, high-performance and cost-efficient products and technologies for cold milling, soil stabilization, hot and cold recycling, concrete paving and surface mining, WIRTGEN leads the world market in road construction and repair, as well as in mining natural rock and pay minerals.
