As infrastructure growth significantly is tied to lessening greenhouse gasoline emissions, merchandise like Wirtgen’s new KMA 240i Chilly Mixing Plant and its WR sequence cold recyclers could obtain in desire.
The organization is launching the earth premiere of the KMA 240i mixing plant, which it states delivers “climate-friendly and price tag-efficient recycling of development supplies.” It is also announcing some technological updates to its WR collection of cold recyclers.
The KMA 240i mixing plant can be stationed in the vicinity of the design web-site wherever resources this kind of as asphalt millings or crushed demolition debris can be delivered to it. The plant then mixes the product with h2o binding brokers like foamed bitumen, bitumen emulsion, or cement. The blended materials can then be applied for paving.
In addition to chilly mixes for bituminous certain base layers, the plant can also generate mixes for cement-stabilized foundation levels and roller compacted concrete at costs of up to 240 tons per hour, Wirtgen states. “These building elements are built-in in the highway construction cycle as large-good quality mixes. They can be utilised for applications ranging from freeway, street and path construction to the construction of parking lots or industrial regions.”
The plant’s higher generation speed is owing to Wirtgen’s “double trough technological innovation,” which doubles the processing pace. “The program allows exact, trusted and automated addition of massive quantities of hydraulic binding brokers,” the business states. “As a outcome of this, the mix production process achieves the maximum amounts of effectiveness and high-quality.”
The process also features automatic self-calibration and precision weighing for the continual addition of binding brokers for the duration of the constant mixing system, in accordance to Wirtgen.
Milled recycled asphalt pavement or other granular substance from outdated highway surfaces and products from the demolition of strengthened concrete can also be recycled and mixed.
“The 100% recycling rate enables significant CO2 (emissions) reductions and energy personal savings, though at the same time reducing venture costs and timeframes,” the corporation claims.
The mixing plant is mounted to a flatbed semitrailer and has its personal engine. It is designed to be swiftly moved and established up at different destinations.
WR collection updates

The company’s new Resource Efficiency System provides an automated, satellite-primarily based steering program that will increase precision down to the centimeter, Wirtgen suggests. It also merchants all of its info of significant parameters for examination and documentation. The details are also compatible with motor graders and compactors on the identical undertaking. When soil stabilizing, it collects facts on these kinds of matters as doing work width and depth, distance and area worked and fuel consumption.
Wirtgen has also produced a new VARIO injection bar for the WR sequence. It regulates the addition of drinking water and binding brokers primarily based on this sort of parameters as functioning width and depth, content density and the machine’s vacation velocity. The bars every have a max of 16 nozzles. The nozzles can be individually managed to vary spraying width. The adjustable nozzles can also regulate injection force and the depth of the spray jets into the milled granulate, the business suggests. “The end result is an even a lot more even distribution of water, bitumen emulsion, or foamed bitumen all through the overall mixing chamber.”
