Description
Efficient heating of asphalt surfaces
-
Powerful, infrared heaters, which can be variably adjusted to the working width, heat the asphalt concrete gently and evenly.
-
The heating power of the infrared heaters can be precisely adjusted using the centrally positioned gas regulation station.
-
The hydraulic, smooth-running all-wheel steering allows for optimum manoeuvrability and mobility.
-
Intelligent folding mechanisms with hydraulically driven rope winches enable the machine to quickly move into its operating or transport position.

Features
- Mixing procedures: Cold recycling can be achieved either in-plant by hauling material recovered from an existing road to a central depot where it is fed through a mixing unit, or in-place using a recycling machine. When mixing in-place / in-situ, a cold recycler granulates the existing pavement while mixing in binders and water homogeneously at the same time. When mixing in-plant, reclaimed asphalt pavement and crushed stone are transported to a mixing plant located in the vicinity of the construction site.

- Hot recycling: Provided that the lower pavement layers are intact in terms of bearing capacity, hot recycling is the most economical and environmentally friendly rehabilitation method for asphalt surface courses. Many different types of surface damage extending to a depth of up to 5 cm on main traffic arteries, minor roads, motorways or airports – such as rutting, cracking, lack of skid resistance, pavement irregularities, incorrect aggregate composition or excessive bitumen content – are repaired by the high-performance machines from WIRTGEN on a large scale and in an extremely short period of time.
