The Wirtgen WR2500S soil stabilizer is equipped with a microprocessor-controlled foam bitumen spray bar, which has 16 individual nozzles and expansion chambers insuring the even distribution of foam throughout the process.
This video show the basic operation of the foam spray nozzles and expansion chamber. The Hot Bitumen entering the nozzles, mixing with the precise amount of water and air to produce the foamed bitumen.
The Foamed Bitumen is then mixed with recycled road material (and stabilizing agent if needed) to create a stronger, higher load-carrying base for road reconstruction.
Please see our video “Recycling” for a more complete look at the mixing process.
