There doesn't have to be a separation between moves towards sustainability and more environmentally friendly products, machines, and operations in the road building industry, and profitability. Never is that fact more clear than with the gradual, yet increasing innovations in the field of autonomous machine operations. Now, more than ever, global demand has reached a new heights for quality, responsible resource handling in the realms of soil stabilization and cold recycling. Now with the release of the Autotrac systems for the WR series, Wirtgen makes available one of the best technologies for exactly these particular types of tasks.
These systems make possible highly precise, automated control of the WR Wirtgen recyclers, resulting in a highly efficient and terrain adaptable process. Autotrac is able to steer the machines within a few centimeters. This level of precision is achieved on the basis of reference strips that are calculated beforehand, and the overlap of adjacent strips. The system then relies on a network of global navigation satellites for the the determination of the machines exact position and direction it will travel. Concurrently, the system allows for the use of an additional control panel by a human operator that delivers real-time information about the position of the machines and the progress of the job.
What this potentially delivers for those who employ it, will be a vastly more efficient use of time and resources. When you take into account the large amounts of overlapping passes that are either avoidable or unnecessary by human operators, the possible financial benefits come into clear view. A WR WIrtgen Autotrac machine boasts the ability to shorten project completion times, reduce carbon footprint, improve overall efficiency, and lower resource consumption.
The importance of properly prepared sub-base layers are widely understood, and the use of soil-stabilizers a great example of a resource efficient method to use when preparing road beds over the course of any scale infrastructure job. Stabilizers can transform a sub-base strata that would fail to stand up to load bearing scrutiny, into firm foundations that can greater withstand heavy abuse. Stabilizers work by taking the present soils and other materials and adds binding agents, and the WR series machines can take damaged asphalt, mill and resize them in one simple operation. These new layers are re-bound by adding fresh agents and water before being repaved in place.
When a new base is produced through this method, it is usually characterized as more resilient with an extremely high load bearing capacity.
